摘要： A polymer electrolyte fuel cell may include a stack of unit cells that each have a hydrogen-ion conductive polymer electrolyte membrane and an anode and a cathode sandwiching the polymer electrolyte membrane. Separators are provided between each two adjacent unit cells and include channels for supplying fuel and oxidant gas to the anode and the cathode. Anode side and cathode side current collector plates sandwich the stack of unit cells. The anode side current collector plate has a terminal section for a power output coupling and is located closer to an inlet-side manifold than to an outlet-side manifold for the fuel gas. The cathode side current collector plate has a terminal section for a power output coupling and is located closer to an inlet-side manifold than to an outlet-side manifold for the oxidant gas.

摘要： In an electrode-membrane-frame assembly production method, a principal part is formed by an electrolyte membrane, first and second catalyst layers and first and second gas diffusion layers, with the first and second gas diffusion layers arranged with their outer circumferences at different positions. The principal part is arranged in a molding die with a circumferential region of the principal part disposed on a flat region of a primary molded body. A circumferential portion of one of the gas diffusion layers is arranged to oppose a flat region of the primary molded body so that the membrane is interposed between the circumferential portion and the flat region. Subsequently, a secondary molded body is formed to integrate with the primary molded body and the principal part.
