CATALYST FOR FUEL CELL, MEMBRANE ELECTRODE COMPLEX, AND SOLID POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for a fuel cell of which the carrier itself carrying a metal catalyst has conductivity, and which can prevent the coagulation of the metal catalyst caused by a long period of use of the fuel cell.

SOLUTION: The catalyst for the fuel cell used for a cathode-side catalyst electrode layer of a solid polymer electrolyte fuel cell has the metal catalyst and a perovskite complex oxide (ABO3).
