CATALYST FOR FUEL CELL CONTAINING RuTe2, ELECTRODE MATERIAL FOR FUEL CELL USING THIS CATALYST FOR FUEL CELL, AND FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for RuTe2based fuel cell which is of low cost and can substitute a noble metal catalyst such as platinum and demonstrates a superior catalyst action, and which is superior in applied voltage durability.

SOLUTION: This is a catalyst for the fuel cell which contains RuTe2as an active component, and the half width of a maximum diffraction peak in a region of diffraction angle 2θ (±0.3) 27° or more and 29° or less by X-ray diffraction method (Cu-Kα line) of RuTe2is 1.80° or less. The RuTe2in which the half width of the maximum diffraction peak shows a specific value is superior in applied voltage durability, and realizes a catalyst for the fuel cell having a practicability capable of substituting a noble metal catalyst such as platinum.
