PROTON EXCHANGE MEMBRANE FUEL CELL HAVING INCREASED PERFORMANCE

摘要

A fuel-cell stack includes a proton-exchange membrane, a first electrode, a second electrode, a first current-collecting metal plate, a first gas diffusion layer, and first and second layers that contact each other. The first electrode and second electrodes are fixed on corresponding sides of the membrane. The first gas diffusion layer is interposed between the first current-collecting plate and the second electrode. The first layer is fixed on the first current-collecting plate, while the second layer is fixed to the first gas diffusion layer. Both layers include a polyurethane matrix containing conductive fillers. The second layer makes contact with the first layer.
