FUEL ELECTRODE MATERIAL AND SOLID OXIDE FUEL CELLS USING COMPOSITE

摘要

PURPOSE: A fuel electrode material is provided to improve elecroconductivity and catalyst activation and to suppress the deposition of carbon inside the fuel electrode, thereby improving the durability of the fuel electrode. CONSTITUTION: A fuel electrode material has a perovskite type crystal and a composition of chemical formula 1: A_(1-x)A'_xB_(1-y)B'_yO_3. In chemical formula 1, A and A' are different and represent one or more element selected from Sr, Y, Sm, La and Ca; B is one or more elements selected from Ti, Mn, Co, Fe and Ni; B' is different form B and represent one or more elements selected from transition metals; x is the number of 0.001-0.08; and y is the number of 0.001-0.5.
