<P>PROBLEM TO BE SOLVED: To provide a flowing field structure of a kind of a fuel cell electrode plate, that is, a structure in which a gas is made to be uniformly circulated through respective gas channels of the fuel cell electrode plate, and reactions of the gas circulated through the respective gas channels and catalysts are uniformly made in the respective channels. <P>SOLUTION: In this flowing field structure of the fuel cell electrode plate, the electrode plate is equipped in which a gas inlet is formed on a first flank, and a gas outlet is formed on a second flank. A plurality of gas slots are formed on the surface of the electrode plate, and a first gas-introduction flow groove is formed at the position mutually adjacent to the gas inlet of the first flank. The first gas-introduction flow groove is provided with a gas-introduction section and a gas lead-out section, and a second gas-introduction flow groove is formed at the position mutually adjacent to the gas outlet of the second flank, and a gas-introduction section and a gas lead-out section are formed at the second gas-introduction flow groove. One end of the gas slot is communicated with the gas inlet, the other end is communicated with the gas-introduction section of the second gas-introduction flow groove toward the direction of the second flank, and furthermore, the gas lead-out section of the second gas-introduction flow groove is communicated with the gas-introduction section of the first gas-introduction flow groove toward the direction of the first flank, and furthermore, the gas lead-out section of the first gas-introduction flow groove is communicated with the gas outlet of the second flank. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
