- the invention finally relates to a device for producing electrical energy of the fuel cell type comprising at least one electrochemical cell comprising a cathode which is such an electrode.
- a battery, or secondary battery such as an electrochemical cell, converts chemical energy ⁇ into electrical energy.
- hydrogen for example from any carbon-based fuel such as gas, a petroleum-based petroleum product, or methanol, is combined with oxygen drawn from the air to generate electricity, water and heat by means of an electrochemical reaction.

They are potentially interesting by their high electrical efficiency, (generally around 50 to 70%), and by the use of the heat they produce.
- Current SOFC materials operate at temperatures of approximately 900 to 1000 ° C. They are explained below.
- the most common solid electrolyte used is zirconia stabilized with yttrium or SZ (acronym for "Yttria Stabilized Zirconia” in English).
