NOVELTY - A membrane electrode assembly (10) has anode (30) and cathode (20) each having catalyst layer (22,32) and gas diffusion layer (26,36), and polymer electrolyte membrane (40) arranged between the catalyst layer (22) of cathode and catalyst layer (32) of anode. The anode and/or cathode has an intermediate layer (24,34) between the catalyst layer and gas diffusion layer. The intermediate layer contains carbon fiber, ion exchange resin (I) and preset amount of platinum. The catalyst layer contains catalyst containing platinum and ion exchange resin (II).    USE - Membrane electrode assembly for polymer electrode fuel cell for motor vehicles and fixed apparatus.    ADVANTAGE - The membrane electrode assembly has high output voltage with current density of wide range.    DETAILED DESCRIPTION - A membrane electrode assembly has anode and cathode each having catalyst layer and gas diffusion layer, and polymer electrolyte membrane arranged between the catalyst layer of cathode and catalyst layer of anode. The anode and/or cathode has an intermediate layer between the catalyst layer and gas diffusion layer. The intermediate layer contains carbon fiber and ion exchange resin (I). The catalyst layer contains catalyst containing platinum and ion exchange resin (II). The intermediate layer contains 3-40 atomic% of platinum with respect to 100 atomic% of total platinum contained in the catalyst layer and intermediate layer. 90 atomic% or more of platinum contained in the intermediate layer exists in the region from the interface of catalyst layer and intermediate layer to 1/2 of thickness of the intermediate layer. An INDEPENDENT CLAIM is included for manufacture of membrane electrode assembly.    DESCRIPTION OF DRAWING(S) - The drawing shows the sectional drawing of the membrane electrode assembly.
