Abstract
A fuel cell with a solid oxide (SOFC) or a molten carbonate salt electrolyte (MCFC). The anode of the fuel cell, according to the invention, is a CERMET anode which consists of a solid mixture of tungsten carbide and an ion-conducting oxide, such as yttrium-fully stabilized zirconium oxide (YSZ). The fuel cell anode is prepared by a process whereby in order to form the solid mixture of which the anode is formed, a mixture of anion-conducting oxide powder and WC/WC(O), WO.sub.3 or precursor thereof is prepared, and this mixture is converted into a YSZ-WC mixture in a CO/CO.sub.2 atmosphere in a temperature range of 600.degree.-1000.degree.
