PROBLEM TO BE SOLVED: To improve cell characteristics, such as a cell voltage, by preventing stay of water in an electrode layer, especially stay of water near an interface of a gas diffusion layer and a catalyst layer in a fuel cell. SOLUTION: In an anode 20, both pores 211 in a catalyst layer 21 and pores 222 in a gas diffusion layer 22 are set to have a diameter distribution so that it may have a peak in a range of 0.1 μm or less. Moreover, also in a cathode 30, both diameter distributions of pores 311 and pores 32 are set to have a peak in a range of 0.1 μm or less. |
