Definitions
- the invention relates to a bipolar plate made of a chromium oxide-forming alloy of a high-temperature fuel cell with a layer that reduces corrosion effects in the area of the gas guiding surfaces, as well as a manufacturing method for this plate.
- a bipolar plate and a manufacturing method are known from DE 44 10 711 Cl.
- a high temperature solid oxide fuel cell enables a direct conversion of chemical into electrical energy.
- the fuel H 2 , CH 4 / CO etc.
- the oxygen-conducting solid electrolyte Y-stabilized Zr0 2 .
- oxygen ions are passed through the electrolyte from the cathode side and react with the fuel at the anode. Because of the charge equalization, an electron current flows in the same direction.
- the electrolyte must be coated with porous, catalytically active electrode materials.
- the anode (fuel side) made of a Ni / Zr0 2 cermet
- the cathode (oxygen side) made of LaMn perovskite.
- the voltage that can be tapped from an individual cell is quite low (less than 1 V).
- a further cell component is necessary, namely the bipolar plate, which is also called the interconnector.
- the bipolar plate in the SOFC flat cell concepts discussed today is a few millimeters thick and forms not only the gas-supplying connecting link between the individual cells, but also that load-bearing component of the cell (EP 0338 823 AI).
- the bipolar plate must therefore have the following properties: sufficient mechanical strength, gas tightness, simple (inexpensive) producibility, thermal expansion which is similar to ceramic electrode materials, good electrical conductivity, corrosion resistance in the oxidizing gas (air) and the fuel (H 2 0 / H 2 ) and compatibility with the electrode materials.
- Two material groups are currently being discussed as bipolar plate material: ceramics based on LaCr0 3 and metallic high-temperature materials. The latter are becoming better because of better toughness electrical conductivity and easier machinability favored. Due to the required hot gas corrosion resistance, only Cr 2 0 3 or A1 2 0 3 forming high-temperature materials are suitable.
- alloys forming Al 2 0 3 with very slow layer growth do show better corrosion resistance than alloys forming Cr 2 0 3 .
- problems arise due to the Al 2 0 3 formation because of the increase in contact resistance at the contact points between the bipolar plate and
- chromium oxide-forming alloys are provided as the interconnector material, and above all alloys based on Cr or FeCr. They have the additional advantage of a low coefficient of thermal expansion.
- the relatively quickly forming, thicker oxide layers are mechanically unstable. They flake off and can thus impair the gas flow in the gas channels during long-term operation.
- the thick Cr 2 O 3 layers formed after long periods of time have low electrical conductivity and, at high oxygen pressure (as prevails on the cathode side), form volatile chromium oxides or hydroxides which form the cathode or the cathode / electrolyte interface "poison".
- DE 44 10 711 Cl provides for a chromium oxide-forming alloy to be provided as the bipolar plate material.
- the alloy is provided with a protective layer made of aluminum in the area of the gas guiding surfaces.
- the aluminum layer changes on its surface into an Al 2 0 3 layer.
- the Al 2 0 3 layer reduces corrosion effects.
- the object of the invention is to create a bipolar plate in addition to a simple production process which is resistant to oxidation, has good conductivity at the interface with the electrode and has a low evaporation rate of volatile chromium oxide / hydroxide.
- the task is solved by a bipolar plate with the features of the device claims. Advantageous configurations result from the related claims.
- the task is also solved by a method with the features of the method claim.
- Electrode contact area is the interface between the bipolar plate and the electrode.
- a mixed oxide layer to increase the conductivity and reduce the evaporation rate z. B. achieved by applying a thin layer of a metal or metal oxides, which forms a mixed oxide (z. B. of spinel type) at high temperature use with Cr or / and Cr 2 0 3 at the oxide / Ga ⁇ interface.
- This mixed oxide must have a lower evaporation rate than Cr 2 0 3 and must also increase its electrical conductivity by incorporating the metal ions into the Cr 2 0 3 .
- Suitable metals or their oxides are e.g. B. Ni, Co or Fe, the influence of Ni on the electrical conductivity of Cr 2 0 3 is greatest.
- the metals or their oxides can e.g. B. applied by conventional PVD or CVD processes.
- a cost-effective method for the metals is also galvanic deposition or electroplating.
- a corrosion-reducing, electrically insulating layer is also provided in the area of the gas guiding surfaces. The fact that this layer is electrically insulating makes it possible in a simple manner to selectively produce various protective layers on the bipolar plate which have optimal properties with regard to the requirements.
- an Al 2 O 3 protective layer can be provided in the area of the gas guiding surfaces, which has excellent corrosion-reducing properties.
- This layer is also electrically insulating advantageously enables the application of a different protective layer in the region of the electrode contact areas in a simple, electrochemical manner. It is thus possible to apply a further protective layer with different physical properties, namely electrically conductive properties in the area of the electrode contact area.
- a corresponding chromium oxide-forming alloy according to DE 44 10 711 Cl is coated in accordance with the method in such a way that a surface coating is carried out in the area of the gas guide surfaces, which is electrically insulated and reduces corrosion effects.
- a coating can take place, for example, in the form of an Al 2 O 3 surface coating in the area of the gas guiding surfaces.
- the surface of the bipolar plate is enriched with aluminum, for example.
- the enriched layer is pre-oxidized, so that Al 2 0 3 forms on the entire interconnector surface.
- the oxide layer and the Al-enriched zone are removed from the web surfaces of the bipolar plate (ie from the contact surfaces with the electrodes) by a conventional grinding process.
- the layer thickness should be a few micrometers. A layer thickness of 1 to 3 ⁇ m is particularly suitable.
- the surface is then electrochemically coated with metals, from which an oxide layer with higher conductivity and lower evaporation rate is formed in comparison to the chromium oxide-forming alloy when used in the fuel cell. It is coated by an electrochemical process so that no more coating takes place in the area of the gas guiding surfaces.
- a galvanic coating for example, serves this purpose.
- Suitable metals are e.g. B. nickel, cobalt or iron. This results in a layer-like enrichment in the sense of the subordinate device claim.
- the process thus produces a selectively coated bipolar plate which consists of a chromium oxide-forming alloy.
- This has a protective layer in the area of the gas guiding surfaces, which reduces corrosion effects and is an electrical insulator. For example, it is a thin Al 2 0 3 layer. Otherwise, it is covered with a metal layer on the electrode contact surface. Suitable metals are in particular Fe, Ni or Co, since these modify the physical properties of Cr 2 0 3 in the desired manner.
- Chromium, NiCr-FeCr, chromium-nickel alloys are suitable as bipolar plate materials. However, chromium or iron-chromium alloys are preferably used.
- Aluminum-existing enrichment layer on the gas channel walls should have a thickness between 20 and 200 ⁇ m, in particular 50 to 100 ⁇ m.
- the metallic layer on the web surfaces should be 1-10 ⁇ m, in particular 1-3 ⁇ m.
- 1 shows a section through a bipolar plate arranged between the anode and cathode; 2 section of a bipolar plate and the individual steps in the selective coating.
- the bipolar plate 1 made of a chromium dioxide-forming alloy, specifically a Cr-based alloy for T> 900 ° C. or for T ⁇ . 900 ° C a ferritic steel with 12-35% by weight Cr.
- the typical shape (plate a few millimeters thick with gas channels) can be produced in the conventional manner by machining a sheet metal material or by means of near-net-shape production (near-net-shape method) using powder metallurgical methods (MIM, WPP).
- the webs 2 on the plate 1, which form the side walls 3 of the gas channels 4, are initially made slightly higher than is desired in the final shape (FIG. 2a) in order to finally remove Al enrichment 7 and oxide layers 8 on the contact surfaces 5 between the bipolar plate 1 with the electrodes 6 (end surfaces).
- the bipolar plate thus prepared is subjected to a conventional alitation process.
- the plate is in a powder mixture of an inert material (e.g. A1 2 0 3 , 90%), a chloride / fluoride activator (e.g. NaCl or NH 4 C1, 5%) and Al powder (5 %) at elevated temperature (600 - 1300 ° C) under a protective gas atmosphere (e.g. argon).
- Typical alitation conditions would be 3 hours at 1000 ° C.
- an Al-enriched zone 7 according to FIG. 2a is formed on the surface of the plate (end faces 5 of the webs and walls 3 of the gas channels).
- a Cr-based alloy z.
- Intermetallic phases of the type Cr 5 Al B or Cr 4 Al 9 are different alitation techniques or other methods can be used if this would be desirable for procedural reasons, e.g. B. CVD, PVD or mechanical coating.
- the preoxidation shown in FIG. 2b takes place to form a thin A1 2 O 3 layer 8 on the surface of the interconnector (for example by oxidation in air at 1000 ° C. for 1 h).
- the Al 2 O 3 layer 8 and the Al-enriched layer 7 are removed from the end faces 5 of the webs 2 by a simple, large-area mechanical processing (for example grinding).
- Their initial oversizing corresponds to the thickness of the material to be ground.
- the oversizing should be greater than the thickness of the Al 2 O 3 layer 8 plus the depth of penetration of the aluminum in the Al-enriched zone 7 (see FIG. 2 c).
- a coating (layer thickness 1 - 10 in particular 1 - 3 ⁇ m) with Ni, Fe or Co takes place by an electrochemical process (e.g. galvanic deposition).
- electrochemical process e.g. galvanic deposition
- No metal is deposited here due to the Al 2 0 3 layer on the gas channel walls.
- the deposition takes place, as desired, only on the web surfaces 5, ie at the interfaces of the interconnector with the electrodes (see FIG. 2d). It is thus achieved that the bipolar plate in the
- a thin layer 9 of metal (Ni, Fe, Co) on the base material e.g. Cr-based or ferritic FeCr alloy
- the base material e.g. Cr-based or ferritic FeCr alloy
- the bipolar plate produced in this way forms on the surface 5 of the webs 2 (ie at the contact points with the electrodes) the desired Cr 2 0 3 -based layer which is doped with Fe, Ni or Co and is covered with a mixed oxide (eg CrNi, Cr / Co or Cr / Fe spinel) at the interfaces with the gas, while continues to grow on the walls of the gas channels Al 2 0 3 .
- a mixed oxide eg CrNi, Cr / Co or Cr / Fe spinel
