FUEL CELL

PROBLEM TO BE SOLVED: To provide a fuel cell for discharging a lump of water generated in a passage to the outside by preventing the lump of water generated in the gas passage of a cell unit of the fuel cell from moving to the vicinity or a hole of a diffusion layer and restraining deterioration of power generation capability caused by inflow of the lump of water and realizing to maintain control of stable power generation for a long period. SOLUTION: In the fuel cell having a cathode electrode and an anode electrode connected with both sides of a solid polymer membrane, the passages facing to respective electrodes, and a separator forming the passages, an inflow of the lump of water generated in the gas passage to the diffusion layer is prevented so that a waterproofing moisture-transmitting material is formed at least one between the cathode electrode and the anode electrode, and the passage, and stable control of power generation of the fuel cell is effectively expected.
