ANODE RESISTANT TO OXIDATION-REDUCTION Russian patent published in 2009 - IPC H01M4/86 H01M8/12 

FIELD: physics; fuel.

SUBSTANCE: method is suggested for preparation of hard oxide fuel element (HOFE), which includes the following stages: preparation of substrate layer for anode, application of anode layer onto substrate layer, application of electrolyte layer onto anode layer, baking of prepared structure. At that layer of substrate and/or anode layer contain composition including alloyed zirconium oxide, alloyed oxide of cerium and/or oxide of metal having oxygen-ion or proton conductivity, nickel oxide and at least one oxide selected from the group that contains the following components Al₂O₃, TiO₂, Cr₂O₃, Sc₂O₃, VO_x, TaO_x, MnO_x, NbO_x, CaO, Bi₂O₃, LnO_x, MgCr₂O₄, MgTiO₃, CaAl₂O₄, LaAlO₃, YbCrO₃, ErCrO₄, NiTiO₃, NiCrO₄ and their mixtures. Mentioned composition makes it possible to prevent enlargement of nickel particles by means of introduction of special inhibitors of their growth and, at the same time, to increase strength of ceramic structure of substrate layer and/or anode layer.

EFFECT: increased resistance of anode of hard-oxide fuel element.
