SOLID POLYMER FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell having little deterioration of battery performance due to deterioration of a catalyst metal.

SOLUTION: The solid polymer fuel cell has the following construction. (1) The solid polymer fuel cell includes a membrane electrode assembly in which an electrode including a catalyst layer is jointed on both sides of an electrolyte membrane. (2) The catalyst layer includes an electrolyte in the catalyst layer and an electrode catalyst, and the electrode catalyst contains one kind or two kinds or more of platinum group elements. (3) Platinum group particulates containing at least one platinum group element are included at least in one of the electrolyte membrane or the electrolyte in the catalyst layer. (4) Platinum group ions consisting of at least one platinum group element to constitute the platinum group particulates are contained in at least one of the electrolyte membrane or the electrolyte in the catalyst layer.
