Abstract

PURPOSE:To prevent leak of gas from the boundary of the end portion of a gas diffusion electrode and the separator by providing a groove parallel to the distribution direction of gas flowing the gas diffusion electrode to the contact boundary of the end portion of the gas diffusion electrode and the separator and then burying a seal material within such groove. CONSTITUTION:A recessed groove 8 is provided in the same direction as the gas flow path of gas diffusion electrodes 1, 2 to the sealing part of the end portion 2 of the separator 5 for separately supplying fuel gas and oxidation gas. A dense sealing material 9 having elasticity or a sealing material 9 having fluidity is arranged to this groove 8 and it is placed in close contact with the gas diffusion electrodes 1, 2. Thereby, the oxidation gas and fuel gas flowing the gas flow path of gas diffusion electrodes 1, 2 are prevented to leak to the outside by the sealing material 9 filled in the groove 8 provided to the separator 5. Accordingly, leak of gas from the boundary of the end portion of gas diffusion electrodes 1, 2 and separator 5 is prevented and entry of external gas to the gas flow path, which is the contrary phenomenon of gas leak, is also prevented.
