    摘要： There has been a problem that the cell units cannot bear the load exerted on the units while being stacked since a fuel cell stack including a refrigerant channel formed between cell units each having an even number of electrolyte/electrode structures (MEA) and metal separators which are alternated does not have any structure supporting the separators forming the refrigerant channel in a stacking direction. In order to solve the above problem, in each of a first power generating unit and a second power generating unit, projections formed at the buffer portions of the separators are disposed in the same positions in the stacking direction with the MEA interposed therebetween. Since between the first and second power generating units, the projections of the buffer portions are staggered, the projections of the first and second power generating units are thereby disposed in the same positions in the stacking direction.

    摘要： Disclosed is a fuel cell in which an electrolyte membrane-electrode structure is held between the first separator and a second separator. The electrolyte membrane-electrode structure comprises a solid polymer electrolyte membrane, a cathode-side electrode and an anode-side electrode. An end portion of the solid polymer electrolyte membrane projects outwardly beyond end portions of gas diffusion layers, and the both surfaces of the end portion of the solid polymer electrolyte membrane are held between the first protective film and a second protective film. The thickness of the first protective film is set to be thinner than the thickness of the second protective film.

    摘要： A fuel cell is formed by sandwiching a membrane electrode assembly between a first separator and a second separator. A fuel gas flow field is formed in the second separator. An inlet buffer is connected to the inlet of the fuel gas flow field, and an outlet buffer is connected to an outlet of the fuel gas flow field. The inlet buffer is deeper than the outlet buffer. Therefore, the pressure loss in the inlet buffer is smaller than the pressure loss in the outlet buffer.

    摘要： An oxygen-containing gas flow field is formed on a surface of a cathode side metal separator of a fuel cell. The oxygen-containing gas flow field is connected between an oxygen-containing gas supply passage and an oxygen-containing gas discharge passage. A coolant flow field is formed on the other surface of the cathode side metal separator, on the back of the oxygen-containing gas flow field. The cathode side metal separator has linear guide ridges protruding from an intermediate height area toward the oxygen-containing gas flow field to form a continuous guide flow field, and bosses protruding from the intermediate height area toward the coolant flow field to form an embossed flow field.
