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.
