<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of optimizing a humidity state of a power generating part and enhancing power generating efficiency of the fuel cell, as well as being manufactured at low cost in a simple structure, without needs of changing a constitution of the power generating part itself. <P>SOLUTION: The fuel cell prevents drying up by increasing generation of product water by forming a gas flow channel 9 of a separator 3 jointed to either side face of the power generating part 2 the wider and the shallower as it goes further upstream, and prevents flooding by enhancing a drainage property of the product water by forming the same the narrower and the deeper as it goes further downstream. <P>COPYRIGHT: (C)2010,JPO&INPIT |
