PROBLEM TO BE SOLVED: To provide a fuel cell for allowing the improvement of sealability around a communicating hole of a separator and its manufacturing method. SOLUTION: A cell of the fuel cell composed of a solid polymer electrolyte membrane 18 and an anode diffusion electrodes (22, 26) and cathode diffusion electrodes (20, 24) at each opposed end thereof is composed to be pinched between by the first separator 14 and the second separator 16. The cell of the fuel cell further comprises, for example, communicating holes 36a, 38a or the like provided in a flat surface of the above pair of separators 14, 16 for supplying and discharging one of a fuel gas, an oxidizing gas, and a coolant to and from the cell of the fuel cell, a groove portion 30 provided to encircle the hole, and a fluid sealant S1 applied inside the groove portion 30. The fluid sealant S1 applied to the groove portion 30 is brought into close contact with each other to seal the periphery of the communicating holes 36a, 38a or the like. |
