Abstract
The invention relates to a method for producing a melt carbonate fuel cell comprising a cathode layer made from porous nickel oxide, an anode layer made from porous nickel and a melt arranged between the cathode layer and the anode layer, received in the form of a finely porous electrolyte matrix melt consisting of one or more alkali metal carbonates as electrolytes. In order to produce the cathode layer, a sintered, coated electrode path, coated with catalytically activating particles, made of porous nickel in the fuel cell operation mode is reacted to form nickel oxide. According to the invention, the electrode path is coated with catalytic activating particles made from one or more non-oxidic inorganic metal compounds, which are reacted to form the corresponding metal oxides under gas development. The invention relates to another similar fuel cell with increased activation of the cathode reaction.
