HUMIDIFIER MEMBER, SOLID POLYMER ELECTROLYTE FUEL CELL WITH THIS HUMIDIFIER MEMBER, AND FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To easily remove impurities in reaction gas and humidifying water, prevent drop in cell characteristics, omit an impurity removing device, and make a fuel cell system compact. SOLUTION: This humidifier member is constituted by stacking one or several numbers of a stack comprising a water permeable membrane 7 and a pair of porous supporters 8 for interposing the water permeable membrane; and a humidifying plate 1 comprising a pair of humidifying plate separators 9, 10 installed on the opposite sides of the stack, a pair of humidifying plate separators 9, 10 is composed of the humidifying plate separator 9 having a gas flow plate 11 and the humidifying plate separator 10 having a humidifying water flow plate 13, and activated carbon is contained in at least one of a pair of porous supporters 8, the gas flow plate 11, and the humidifying water flow plate 13.
