Abstract:
An electrochemically active element for a high temperature fuel cell which is designed in layers and comprises an anode layer, a cathode layer and an electrolyte layer which is arranged therebetween, withthe electrolyte being a ceramic material of zirconium oxide ZrO.sub.2 stabilized with yttrium Y,the anode being manufactured from a powder mixture through sintering on the electrolyte layer,and the anode mixture containing oxides NiO and CeO.sub.2 and containing A.sub.2 O.sub.3, wherein A is a member selected from the group consisting of Sm, Y, Gd, Pr, and mixtures thereof, wherein the NiO component of the anode mixture amounts to about 60-80 weight percent,characterized in that 0.5-5 mole percent of a member selected from the group consisting of CoO, FeO, MnO and mixtures thereof is added to the anode mixture in order to lower the sintering temperature of the mixture.
