(54)	ELECTRODE CATALYST LAYER FOR FUEL CELL, MANUFACTURING METHOD FOR SAME, AND MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL USING SAME

(57) Provided is an electrode catalyst layer excellent in gas transportability by using an electrode catalyst layer for fuel cell comprising a catalyst containing a catalyst carrier and a catalytic metal carried on the catalyst carrier and an electrolyte, wherein the catalyst partially is coated with the electrolyte, and a specific surface area of the catalytic metal which gas can reach without passing through an electrolyte is 50% or more, with respect to the total specific surface area of the catalytic metal.
