<P>PROBLEM TO BE SOLVED: To efficiently eject drops of water clogged in a gas flowing path of a flowing path substrate for having reactant gas flow through in a solid polymer fuel cell. <P>SOLUTION: In the fuel cell, both sides of a unit cell which is constituted by joining each of an anode electrode on one surface of an electrolyte film and a cathode electrode on the other surface are sandwiched by flowing path substrates in which gas flowing paths are provided side by side and one or a plurality of this is laminated and integrated. The gas-permeable property of the electrode in the orthogonal direction Y to the gas flow direction X of the flowing path substrate 6 or the gas diffusing layer is set so that it is smaller than the gas-permeable property of the electrode in the gas flowing direction X and the laminated direction Z or the gas diffusing layer. As a specific means, for example, the direction of fiber in the gas diffusing layer of the electrode is made to be approximately in parallel to the direction of the gas flow. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
