Abstract
A fuel cell metal separator is stacked on a membrane electrode assembly to form a power generation cell. The membrane electrode assembly includes an electrolyte membrane and electrodes provided on both sides of the electrolyte membrane, respectively. The fuel cell metal separator includes a bead seal for preventing leakage of a fuel gas, an oxygen-containing gas, or a coolant as fluid. A top of the bead seal is configured to become flat in cross section by application of a compression load to the power generation cell.
