    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.

    摘要: A fuel cell is formed by stacking first cell units and second cell units alternately. An inlet buffer and an outlet buffer are formed on a surface of a first metal separator of the first cell unit. Bosses are provided in the inlet buffer and the outlet buffer of the first metal separator. An inlet buffer and an outlet buffer are formed on a surface of the second metal separator of the first cell unit. Continuous guide ridges are formed in the inlet buffer and the outlet buffer of the second metal separator. The bosses and the continuous guide ridges are provided at positions overlapped with each other in the stacking direction.

    摘要: The present invention relates to a fuel cell separator and a method of producing the fuel cell separator. A first separator and a second separator are provided as the fuel cell separators. Firstly, the first separator and the second separator are heated. Thus, an Fe rich layer is formed in a surface layer of each of the first separator and the second separator, and a Cr rich layer where a proportion of Cr is 60% or more is formed in an inner portion of each of the first separator and the second separator. Then, an electrolytic treatment is applied to each of the first separator and the second separator to remove the Fe rich layer. By the removal, the Cr rich layer is exposed to the outside on the outermost surface layer of each of the first separator and the second separator.
