Abstract
First gas flow passage grooves communicating with a fuel gas inlet and second gas flow passage grooves communicating with a fuel gas outlet are provided on a surface of a first separator. First and second united sections are provided at merged portions of the first gas flow passage grooves and the second gas flow passage grooves. Accordingly, the number of gas flow passage grooves is throttled from the side of the fuel gas inlet to the side of the fuel gas outlet. The turbulence is allowed to occur at the throttled portion to make it possible to improve the gas diffusion performance.
