<P>PROBLEM TO BE SOLVED: To provide a new method to prevent the decomposition of electrolyte polymer material caused by radicals originating from hydrogen permeated through an electrolyte film on an air electrode side catalyst layer of a fuel cell. <P>SOLUTION: The air electrode side catalyst layer is constituted of a first catalyst layer of the electrolyte film side and a second catalyst layer of a dispersion layer side, and catalyst concentration of the first catalyst layer is arranged lower than that of the second catalyst layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
