<P>PROBLEM TO BE SOLVED: To provide a fuel cell with a low contact resistance between an electrode and a separator, in which an MEA (membrane electrode assembly) is constituted of a solid polyelectrolyte film, a fuel electrode and an air electrode on the both sides of the MEA, is sandwiched by separators constituted from a compound of graphite particles and resin and has gas flow paths formed integratedly on its surface, and single cell stacks laminated between separators. <P>SOLUTION: The surface of a separator 16 is irradiated with YAG (yittrium-aluminum-garnet) laser 20 and a skin layer with high resin component formed on its surface is removed by carbonization. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
