ELECTROLYTE MEMBRANE ELECTRODE JUNCTION FOR SOLID POLYMER TYPE FUEL CELL, AND SOLID POLYMER TYPE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte membrane electrode junction for solid polymer fuel cell of which the electrolyte membrane and the electrode are hardly deteriorated, and a solid polymer fuel cell in which the deterioration of battery performance is small even in the case of operation for a long period of time.

SOLUTION: In the electrolyte membrane electrode junction for a solid polymer fuel cell which is constructed of an electrolyte membrane having ion conductivity and a pair of electrodes provided on both sides of the electrolyte membrane, a peroxide decomposition substance composed of at least one kind of an iron-contained oxide and an iron-contained hydroxide is contained in at least one of the electrolyte membrane and the pair of the electrodes. And the solid polymer fuel cell is structured by using such electrolyte membrane electrode junction.
