Beschreibung
Zusammenfassung:[Problem] To provide a practical solid polymer fuel cell having high cell performance and excellent durability.[Means for solving] The polymer electrolyte fuel cell according to the present invention includes: a membrane electrode assembly in which electrodes each including a catalyst layer are joined to both surfaces of an electrolyte membrane; and a peroxide decomposition catalyst which is fixed to the electrolyte membrane and/or the electrodes and includes a hardly soluble carbide, a boride, and/or a silicide. The peroxide decomposition catalyst preferably contains a carbide, a boride and/or a silicide of a rare earth element, a transition metal element or a typical metal element.
