Abstract
The electrochemically active element (1) for a high temperature fuel cell is designed in the form of layers and comprises an anode layer (3), a cathode layer (4) and an electrolyte layer (2) which is arranged therebetween. The electrolyte is a ceramic material of zirconium oxide ZrO,stabilised with yttrium Y which can additionally contain aluminium oxide Al,O,. The anode is manufactured from a power mixture through sintering on the electrolyte layer. This anode mixture contains the oxides NiO and CeO2 and can contain an oxide of the type A,O,, with for example A=Sm, Y, Gd and/or Pr. In accordance with the invention 0.5−5,/,CoO, FeO and/or MnO is or are to be added to the anode mixture in order to lower the sintering temperature of this mixture.
