Membrane Catalyst Layer Assembly, Membrane Electrode Assembly and Polymer Electrolyte Fuel Cell |
| abstract |
Provided is a membrane catalyst layer assembly which can realize a polymer electrolyte fuel cell with excellent durability that can not only sufficiently prevent deterioration of initial characteristics but also exhibit sufficient battery performance over a long period of time. In at least the cathode catalyst layer, the ratio (W P / W Cat-C ) of the mass W P of the polymer electrolyte to the mass W Cat-C of the catalyst-carrying carbon is determined from the innermost layer disposed at the position closest to the polymer electrolyte membrane. , ratio (W P the reduced over the outermost layer disposed in a remote location, the ratio (W P / W Cat-C ) in the innermost layer to 0.8 to 3.0, and also at the outermost layer from the polymer electrolyte membrane / W Cat-C ) is set to 0.2 to 0.6. |
