Poroese sauerstoffverzehrende Elektrode, Verfahren zu deren Herstellung und deren Verwendung

High-temperature fuel cell consisting of a porous fuel gas consuming anode, a porous oxygen consuming cathode, between which there is an electrically insulating porous ceramic matrix and molten carbonate electrolytes, whereby the cathode consists of a porous nickle-oxide matrix and a think electrochemically active non-soluable layer made of a double oxide in the carbonate melt.
