<P>PROBLEM TO BE SOLVED: To provide a technique of improving power generation performance of fuel cells for solving the problem in which: in the case that a shape of a gas channel is an interdigital channel, particularly in a cathode channel, produced water arising along with power generation moves and stays in a tip occluded region of an interdigital primary occlusion channel; the staying produced water inhibits supply of reaction gas to a membrane electrode assembly; and thereby, the power generation performance deteriorates. <P>SOLUTION: A fuel cell comprises: an anode meandering channel 43 meandering back-and-forth along an X-axis direction and guiding fuel gas; and anode downstream channel 45 extending along a Y-axis direction and guiding fuel gas coming through the anode meandering channel 43. <P>COPYRIGHT: (C)2012,JPO&INPIT |
