FUEL ELECTRODE FOR SOLID ELECTROLYTE TYPE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a fuel electrode for a solid electrolyte type fuel cell, in which matching between electrolyte and a fuel electrode is taken. SOLUTION: A nickel oxide powder with low crystallinity is used for the fuel electrode for a solid electrolyte type fuel cell, made by baking nickel oxide powder or mixed power of nickel oxide powder and oxide powder with oxygen ion conductivity. By adjusting the crystallinity of the nickel oxide powder used for raw material of the fuel electrode, its matching with electrolyte can be achieved.
