Beschreibung
Zusammenfassung:	Provided are a fuel cell catalyst which has high power output characteristics and suppresses degradation of power generation performance due to starting, stopping or load variation; a manufacturing method thereof; a membrane electrode assembly (10) for fuel cell (1); and a fuel cell (1) including the same. The fuel cell catalyst according to the present invention is a fuel cell catalyst including at least catalytically active species and a carrier supporting the catalytically active species, wherein the catalytically active species are at least one selected from the group consisting of platinum, a platinum alloy, and a core-shell catalyst in which a core of a metal different from platinum is coated with a shell containing platinum, the carrier is a carbon material, and at least one of the catalytically active species and the carrier contain(s) fluorine atoms.
