CATALYST SUPPORT STRUCTURE AND FUEL CELL ELECTRODE USING CATALYST SUPPORT STRUCTURE AND FUEL CELL

摘要

PURPOSE:To provide a fuel cell which is excellent in discharge performance by previously forming a metal oxide layer on the surface of a support base material in supporting an electrode catalyst and then by forming a platinum group layer to form a catalyst having less deterioration and by forming the electrode of a fuel cell by means of catalyst formed by the above method. CONSTITUTION:A metal oxide layer 2 is formed around a catalyst support base material 1. A platinum group layer 3 is supported on the periphery of the metal oxide layer 2. The metal oxide layer 2 is formed by thermal decomposition method. The support structure of a platinum group catalyst having a large catalyst specific surface area is made by soaking the metal oxide layer in the chloride solution of the platinum group layer.
