<P>PROBLEM TO BE SOLVED: To provide a gas diffusion supply member for a fuel cell excellent in mechanical strength in which gas is sufficiently supplied to an electrode for efficient power generation. <P>SOLUTION: The member faces a power generation element 100 of a fuel cell to diffuse and supply oxidizing gas and reducing gas. It comprises a flow path board 1 on which a plurality of gas flow paths 2 and 3 are provided side by side, with one end as an open end while the other end as a closed end. At least two pairs, a pair composed of gas flow paths of one for flow-in and the other for flow-out, are provided. The gas flow paths 2 and 3 of one of the pairs are formed with gas communication openings 4 and 5 which open at one surface of the flow path board 1, and the gas flow paths 2 and 3 of the remaining pairs are formed with the gas communication openings 4 and 5 which open at the other surface of the flow path board 1. Porous bodies 6 and 7 allow gas to transmit between the gas flow paths 2 and 3 and the power generation element 100. They supply gas toward the electrode surface of the power generation element 100, and allow the gas to remain for an extended period so that it is sufficiently supplied to the electrode. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
