GAS DIFFUSION ELECTRODE WITH A POROUS COATING AND CORRESPONDING PRODUCTION METHOD

摘要

Conventionally, gas-permeable layers are particularly provided on the surfaces of the cathodes of high temperature fuel cells (SOFC) and the oxygen diffusion is significantly reduced as a result of the corresponding application of electrolyte and sintering. According to the invention, an electrode coating may be produced with which the porosity may be defined and remains at this value after sintering. The above is achieved, whereby a pore-forming agent and/or a structural stabiliser are used.
