    摘要： It is a main object of the present invention to provide a fuel cell catalyst in which a support for supporting a metal catalyst has electrical conductivity in itself and which can prevent agglomeration of the metal catalyst during long term use of the fuel cell. In the present invention, the object is achieved by providing a fuel cell catalyst for use in a cathode-side catalyst electrode layer of a solid polymer electrolyte fuel cell, comprising a metal catalyst and a perovskite-type complex oxide (ABO3).
