Definitions
- Ionic conductive membrane Ionic conductive membrane, method of manufacturing such a membrane, electrochemical cell comprising such a membrane and installation comprising such a cell
- the technical field of the invention relates to ionic conductive membranes such as those used in particular in water electrolysis devices. More particularly, the invention relates to a membrane (also called a separator) for the alkaline electrolysis of water and a method for manufacturing such membranes.
- a membrane also called a separator
- Hydrogen is used in several industrial processes, including as a raw material in the chemical industry and as a reducing agent in the metallurgical industry. Hydrogen is a fundamental element for the manufacture of ammonia, and therefore fertilizers, and the manufacture of methanol, used in the manufacture of many polymers. Refineries, where hydrogen is used for the processing of intermediate petroleum products, are another area of use.
- Hydrogen is also an important energy carrier: it can store and provide energy in a usable form. The energy is released by an exothermic combustion reaction with oxygen, forming water. During such a combustion reaction, no carbon-containing greenhouse gases are emitted.
- Alkaline water electrolysis is an important process for producing hydrogen.
- a membrane is used to separate the gases produced as well as to separate the electrodes of different polarities to prevent short circuit between these electronically conductive parts (electrodes) and to prevent the mixing of H2 (formed at the cathode) and 02 (formed at the anode) to avoid explosive mixtures of these gases. While performing all these functions, the membrane is an ionic conductor for the transport of OH ions from the cathode to the anode.
- a porous diaphragm i.e. a diaphragm whose pores have an average diameter greater than 1 micrometer (Ipm): the pores are sought to make the diaphragm ionically conductive because the electrolyte penetrates these pores and under the effect of the electrolysis voltage, allows the circulation of ions (or anions) through the electrolyte absorbed in the pores. But gas bubbles can also easily penetrate these pores, cross the diaphragm and increase the "crossover" (passage of gas through the diaphragm).
- Ipm micrometer
- a gas-tight membrane meaning gas bubble-tight
- a membrane whose pores have an average diameter of less than 1 micrometer (Ipm) or even less than 1 nanometer (Inm).
- Ipm micrometer
- Inm nanometer
- the ionic electrolyte is absorbed by the membrane but the gas bubbles cannot pass through the membrane.
- the membrane is called gas-tight or non-porous.
- microporous membranes comprising hydrophilic inorganic particles, in particular zirconium oxide particles (also called Zirconia).
- zirconium oxide particles also called Zirconia
- Zirfon® membranes comprising zirconium oxide particles bound by a polymer.
- These membranes are microporous (pores with diameters of approximately Ipm); they also have drawbacks, in particular insufficient mechanical and thermal stability, significant permeability to dihydrogen, higher permeability to dioxygen at temperatures above 100 degrees Celsius, limited ionic conductivity, and therefore limited efficiency. Also, these membranes show a limited lifespan in use due to rapid degradation in an alkaline environment requiring frequent membrane changes. All these drawbacks have an impact on the profitability of large-scale hydrogen production.
- the invention provides a new membrane which does not have all or part of the drawbacks mentioned above.
- the invention proposes a novel ionic conductive membrane for an electrochemical device, membrane comprising a layer of a material comprising:
- a powdered ceramic comprising ceramic doped with Yttrium oxide and/or ceramic doped with Cerium oxide.
- a doping process consists in adding impurities (in the context of the invention, yttrium oxide or cerium oxide) to a pure substance (in the context of the invention, a ceramic) in order to modify the crystallographic structure and ultimately the physicochemical properties of the pure substance.
- impurities in the context of the invention, yttrium oxide or cerium oxide
- a pure substance in the context of the invention, a ceramic
- the doped substances used in this case the ceramic doped with yttrium oxide and/or the ceramic doped with cerium oxide, are thus substances which are different from the initial pure substance (the ceramic) from the point of view of their crystallographic structure and which therefore have at least one distinct physicochemical property compared to the initial ceramic.
- a membrane according to the invention consisting of a polymer binder and ceramic doped with Yttrium oxide and/or ceramic doped with Cerium oxide
- the polymer binder is not degraded during operation of the electrolyser by the solvated or free electrons present in the electrolyte of an electrolyser or by the particularly aggressive nascent oxygen atoms "O'".
- the tests thus show that the ceramic doped with Yttrium oxide and the ceramic doped with Cerium oxide have a protective effect against oxidation for the polymer binder.
- the service life of the membrane according to the invention is thus greater than that of membranes known elsewhere, without it being necessary to add a protective layer of the membrane against oxidation.
- the powdered ceramic may comprise:
- Zirconia (or zirconium dioxide ZrO2) doped with Yttria oxide, also called Yttria Stabilized Zirconia or YSZ (for Yttria Stabilized Zirconia), is a ceramic made of zirconium dioxide (ZrO2) whose crystalline structure is stabilized in its cubic or tetragonal form at room temperature by yttria. Zirconia has very good ionic conductivity, so that the electrolysis efficiency is improved. Doping zirconia with Yttria oxide gives doped zirconia a particular antioxidant effect of interest in the context of the invention. Doping with Ceria also provides an interesting antioxidant effect, and Ceria is less expensive than Yttria. [14] In other embodiments, the powdered ceramic may comprise:
- Boron nitride due to its good ionic conductivity, is a good complement to zirconia.
- the polymer binder may be a hydrophobic thermoplastic polymer.
- the water-repellent tendency of the polymer thus enhances its resistance to free electrons and further improves the membrane life.
- the polymer binder is preferably polysulfone (PSU), polyethersulfone (PES), polyphenylene sulfone (PPSU), polytetrafluoroethylene (PTFE) or a mixture of at least two of said polymers.
- PSU polysulfone
- PES polyethersulfone
- PPSU polyphenylene sulfone
- PTFE polytetrafluoroethylene
- the membrane according to the invention is non-porous.
- the surface of the ceramic grains ensures the ionic conduction of the membrane.
- the polymer binder ensures the mechanical connection between the grains; it also makes it possible to obtain a flexible membrane.
- the invention also relates to a ceramic comprising ceramic doped with Yttrium oxide and/or ceramic doped with Cerium oxide, preferably zirconia doped with Yttrium oxide and/or zirconia doped with Cerium oxide, particularly interesting for the manufacture of a non-porous membrane for low temperature electrolysis (0°C to 150°).
- the invention also relates to a cell for an electrochemical device, the cell comprising a membrane as described above; the invention also relates to a water electrolysis installation comprising such a cell.
- the invention finally relates to a method of manufacturing a membrane as described above, according to a phase inversion technique.
- FIG. 2 shows a simplified diagram of a water electrolyser •
- FIG. 3 shows results of tests carried out on the membrane according to the invention.
- the invention relates to an ion-conducting membrane (10) for an electrochemical device, the membrane comprising a layer of a material comprising
- a powdered ceramic comprising ceramic doped with Yttrium oxide or ceramic doped with Cerium oxide.
- the powdered ceramic may comprise:
- zirconia doped with cerium oxide or a mixture of zirconia doped with yttrium oxide and zirconia doped with cerium oxide.
- the powdered ceramic may comprise:
- the polymer binder is a hydrophobic thermoplastic polymer, preferably polysulfone (PSU), polyethersulfone (PES), polyphenylene sulfone (PPSU), polytetrafluoroethylene (PTFE), or a mixture of at least two of these polymers; these polymers are chosen for their mechanical, chemical and electrical properties.
- PSU polysulfone
- PES polyethersulfone
- PPSU polyphenylene sulfone
- PTFE polytetrafluoroethylene
- the material constituting the member comprises 70 to 95% by weight of powdered ceramic, and - 5 to 30% by weight of polymer.
- the surface of the powdered ceramic grains and more particularly the contact surface between the ceramic grains are the seat of the ionic conduction of the membrane, it is therefore important to maximize these contact surfaces to obtain a membrane that is as efficient as possible, in terms of ionic conduction and therefore electrolysis efficiency.
- the polymer provides the link between the grains and thus the mechanical strength of the membrane.
- the membrane obtained is non-porous, the ionic conduction taking place on the contact surfaces of the ceramic grains.
- the proportion by weight of powdered ceramic and polymer thus results from a compromise.
- the efficiency of the membrane, particularly in terms of ionic conduction, is satisfactory when the material comprises more than 70% by weight of ceramic, - the mechanical strength of the membrane is sufficient for the intended applications when the material contains more than 5% by weight of polymer binder.
- the doped ceramic may comprise:
- the ceramic doped with yttrium oxide or with cerium oxide has a protective effect against degradation by oxidation of the binder polymer: tests have shown for example that the polymer of a membrane comprising powdered ceramic comprising doped zirconia comprising at least 1% by weight of yttrium oxide degrades little and that the polymer of a membrane comprising powdered ceramic comprising doped zirconia comprising at least 5% by weight of yttrium oxide does not degrade or degrades very little compared to the polymer of a membrane comprising conventional zirconia.
- the doped ceramic could comprise more than 25% by weight of Yttrium oxide; however, the cost of Yttrium oxide being particularly high, the cost of the membrane would become too high compared to the expected yield.
- the powdered ceramic grains have an average diameter of between 0.1 and 5 pm, and preferably between 0.2 and 2 pm.
- the ionic conductivity of the membrane is directly linked to the apparent surfaces (not covered with binder) of the grains in the membrane and more particularly to the contact surfaces or surfaces close to adjacent grains promoting ionic exchanges between the grains.
- the membrane described above can be produced according to a method comprising a phase inversion step.
- a phase inversion step here consists in causing the removal of a solvent from a solvent-polymer solution, by immersing a film of solution in a non-solvent.
- a step allows the transformation of the solvent-polymer solution film into a polymer membrane.
- a method according to the invention comprises the following steps.
- step 1 the polymer is dissolved in a water-immiscible solvent to obtain a polymer solution.
- a mass of polymer polysulfone (PSU)
- DMAc dimethylacetamide
- the ceramic powder is then added (step 2) to the polymer solution.
- the amount of ceramic powder added is such that, relative to the total weight of the polymer and ceramic, the polymer represents 5 to 30% by weight and the ceramic represents 70 to 95% by weight.
- the ceramic powder comprises ceramic doped with yttria and/or ceramic doped with ceria, preferably zirconia doped with ceria and/or, as in the present example, zirconia doped with yttria (YSZ). The whole is mixed to obtain a viscous homogeneous membrane solution.
- a mass of doped Zirconia powder is dispersed in DMAc solvent and then the solution containing the ceramic and the polymer solution obtained in the previous step are mixed for 45 to 60 min until a membrane solution is obtained that is more viscous than the two initial solutions.
- the membrane solution is then cast (step 3) onto a support to form a film.
- the support is preferably flat. If necessary, in particular depending on its viscosity, the membrane solution is stretched simultaneously with casting.
- the casting parameters are adjusted according to the desired dimensions of the membrane and the parameters of the membrane solution (in particular the viscosity of the membrane solution and the shrinkage power of the polymer binder during the following steps).
- the film-covered support is then immersed in a non-solvent (step 4) to cause phase inversion.
- the membrane solution precipitates, the solvent is replaced by non-solvent, especially on the surface and inside the film.
- the support on which the film rests is immersed in water (the non-solvent here), which replaces the DMAc (the solvent) remaining in the membrane film.
- the non-solvent here
- two phases are in equilibrium: a solid phase, rich in polymer which forms the structure of the film and a liquid phase (poor in polymer) which constitutes the pores of the membrane filled with water here.
- the viscosity of the polymer-rich phase increases until reaching a state where the precipitated polymer is considered a solid.
- the membrane solution film is thus transformed into a solid, flexible membrane which traps ceramic grains.
- a rolling step (step 7) of the membrane can be carried out to homogenize the surfaces, remove open porosities to further improve the non-porous character of the membrane and/or improve the mechanical strength of the membrane.
- the rolling step can be carried out at any time after the end of the transformation of the membrane solution film by phase inversion.
- the rolling step can thus be carried out before extracting the support and the membrane from the water (step 5), or after extracting the membrane from the water.
- the rolling step also makes it possible to obtain a membrane of regular thickness.
- the rolling step can be repeated several times if necessary to obtain a membrane having the required properties, in particular a non-porous membrane.
- a heat treatment step may be performed to strengthen the bond between the polymer and the ceramic grains and/or to further reduce the pore size in the membrane.
- the membrane can be rolled up and stored.
- the membrane described above may be produced by another method, in particular when it is produced with PTFE, another method comprising the following steps, consisting of:
- the powdered ceramic comprising ceramic doped with yttrium oxide and/or ceramic doped with cerium oxide, preferably zirconia doped with yttrium oxide and/or zirconia doped with cerium oxide, and mixing to obtain a homogeneous membrane paste,
- FIG. 1 shows a diagram of a known cell for a water electrolysis plant for the production of hydrogen H2 and oxygen 02 gas.
- Figure 2 shows a schematic diagram of a membrane water electrolysis plant.
- the membrane 10 divides a bath into two, a bath comprising a mixture of water and electrolyte.
- the cathode 20 and the anode 30 are positioned on either side of the membrane and are connected respectively to the negative and positive terminals of an electrical energy source.
- the membrane 10 allows good separation of the hydrogen gas produced on the cathode and the oxygen gas produced on the anode.
- the cathode and/or the anode may be porous.
- the cathode and anode can be metallic, for example nickel, stainless steel or metal oxides, especially on the anodic side. Nickel and stainless steel form surface oxides which are catalysts for the release of oxygen. 316L stainless steel is particularly effective thanks to its molybdenum content.
- a single cell is shown in Figure 1. However, in practice, an industrial installation may comprise several cells, or even a hundred cells.
- Figure 3 shows results of tests carried out with a PSU/YSZ membrane according to the invention, in an electrolyser cell comprising a bath of a mixture of water and potassium hydroxide (KOH) at 4 mol/l, at a temperature of approximately 90°C.
- Figure 3 shows more precisely the evolution of the voltage at the terminals of the cell as a function of the current density flowing between the electrodes.
- the HHV (high heating value) efficiency of the cell can be calculated by dividing 1.48 V by the voltage at the terminals of the cell; 1.48 V is a reference value corresponding to the thermodynamic voltage for dissociation of water, a reference value to which a theoretical efficiency of 100% is associated.
- the voltage across the electrodes is 1.72V, corresponding to an efficiency of 86% HHV.
- the voltage across a cell comprising a known Zirfon membrane is 2.1V, i.e. an efficiency of 70% HHV.
