Abstract
A first gas diffusion layer for constructing an anode electrode and a second gas diffusion layer for constructing a cathode electrode are provided with first and second gas flow passages which are formed opposingly to first and second flow passages provided on first and second separators respectively. A fuel gas is supplied to the first flow passage and the first gas flow passage, while an oxygen-containing gas is supplied to the second flow passage and the second gas flow passage. Accordingly, the fuel gas and the oxygen-containing gas are uniformly diffused and supplied to first and second electrode catalyst layers respectively.
