    摘要: A solid polymer fuel cell which can stably generate electric power for long, because the cell is enabled to uniformly supply a fuel gas to all anodes by means of extended flow passages which are extended from anode-side flow passages and formed on a anode-side plate on the downstream side of the ends of the anodes in the direction of fuel gas flow, a water absorbing means for nearly uniformly performing water absorption, water retention, and drainage on all channels provided at the ends of the extended flow passages, and a selective gas discharging means for discharging a gas more selectively than water on the upstream side of the water absorbing means. In addition, the power generation characteristics and service life of the fuel cell can be improved further, because the cell can maintain a solid polymer film in a moist state as a whole and can efficiently supply the fuel gas to all anodes by a means for distributing the fuel gas to the inlet sections of the anode-side flow passages and a means for distributing water from a water source to the inlet sections of the anode-side flow passages through holes having a prescribed form and leading to the inlet sections of the anode-side flow passages.

    摘要: A water-retaining layer is formed to coat the top of ribs of a ribbed plate which is to be disposed, as a component of a polymer electrolyte fuel cell, on at least one surface of a cell which includes an electrolyte membrane and two electrodes disposed on two surfaces of the electrolyte membrane. The water-retaining layer is formed by: generating a mixture by dissolving a resin-carbon mixture into a solvent; applying the mixture using a spray to a surface of the ribbed plate having the ribs; and drying the applied mixture at a certain temperature. The ability to retain water in the water-retaining layer per unit active area of the electrodes is desirably in the range of 0.002 to 0.035 g/cm2, and more desirably, in the range of 0.01 to 0.03 g/cm2.
