    摘要： A polymer electrolyte fuel cell is provided with a conductive separator having one or more gas flow channels for supplying and exhausting a gas to and from an electrode of the fuel cell. The gas flow channels are connected to and in fluid communication with an inlet manifold on the separator. The cell also includes a gas supply connection in fluid communication with the inlet manifold of the separator. Water accumulation in the cell can be advantageously reduced by configuring the connections to the inlet manifold so that the lowermost part of any gas flow channel connections with the inlet manifold is above the uppermost part of the gas supply connection to the inlet manifold.

    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.
