摘要： A first metal separator and an electrolyte electrode assembly are stacked in a fuel cell. The first metal separator comprises a convex portion that abuts against the electrolyte electrode assembly, and a concave portion forming an oxygen-containing gas flow channel between the electrolyte electrode assembly and the concave portion. A gold coating layer is formed on the convex portion. The gold coating layer includes a main gold coating portion and a reticulate gold coating portion that extends around the main gold coating portion.

摘要： A first separator to which a resin film is joined beforehand is set in a cavity formed between a lower die and an upper die of an injection molding machine. At the time of die locking by moving the upper die toward the lower die, in the case where the total thickness of the resin film and the first separator is larger than a predetermined dimension, the resin film is pressed by the lower die or the upper die, and thus, the resin film is deformed by compression within its elastic deformation range.

摘要： A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first metal plate of the fuel cell and the second metal plate of the adjacent fuel cell. A folded section is provided around a coolant supply passage by folding the second metal plate. The folded section forms an inlet which enlarges the sectional area of an opening as a fluid passage between the coolant supply passage and the coolant flow field.

摘要： A first metal separator of one of adjacent power generation cells and a second metal separator of the other of the adjacent power generation cells are directly stacked together to form a coolant flow field. The first metal separator has a press line protruding toward the coolant flow field, between a fuel gas flow field and an inlet buffer. The second metal separator has a press line protruding toward the coolant flow field, between an oxygen-containing gas flow field and an inlet buffer. The press lines contact each other to limit flow of the coolant into a back surface buffer.

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.
