ELECTRODE MATERIAL, MEMBRANE-ELECTRODE ASSEMBLY, FUEL CELL STACK AND METHOD FOR MANUFACTURING ELECTRODE MATERIAL

摘要

An electrode material (10) according to one embodiment includes an electrode catalyst (13), which includes a conductive support (12) supporting an active catalyst (11), and a porous inorganic material (14) partially coating the electrode catalyst (13). The pore surfaces of the porous inorganic material (14) are modified by a basic functional group (15). Mainly, an electrolyte (ionomer) (16) having proton conductivity is mixed into the electrode material (10).
