PROBLEM TO BE SOLVED: To provide a membrane-electrode assembly for a direct alcohol type fuel cell, in which the oxidization reaction of alcohol being fuel is accelerated by the cooperation between platinum and an alcohol oxidation acceleration metal, and to provide a direct alcohol type fuel cell that has the membrane-electrode assembly. SOLUTION: The membrane-electrode assembly for a direct alcohol type fuel cell is configured, such that an anode catalyst layer includes a platinum-alcohol oxidization acceleration metal alloy; the content ratio of an alcohol oxidization acceleration metal in the platinum-alcohol oxidization acceleration metal alloy is less than 15 mol% at the upstream end, in the flow direction of supplied alcohol, when expressed in terms of mole percent, while being a value that exceeds 15 mol% at the downstream end of the flow direction. The content ratio of the alcohol oxidization acceleration metal increases monotonously, from the upstream end to the downstream end of the flow direction. COPYRIGHT: (C)2009,JPO&INPIT
