Abstract:
A fluid passage for supplying or discharging fluid extends through a metal separator in a separator thickness direction, and a bead seal configured to prevent leakage of the fluid protrudes from the metal separator. A folded portion is formed in an outer marginal portion of the metal separator or in an inner marginal portion of the fluid passage, and the folded portion is bent or curved in a direction opposite to the protruding direction of the bead seal.

Claim (Index 7):
A method of producing a fuel cell metal separator configured to be stacked on a resin frame equipped membrane electrode assembly to form a power generation cell, the resin frame equipped membrane electrode assembly including a membrane electrode assembly and a resin frame member provided at an outer periphery of the membrane electrode assembly, a fluid passage configured to supply or discharge an oxygen-containing gas, a fuel gas, or a coolant as fluid extending through the fuel cell metal separator in a separator thickness direction, and a bead seal configured to prevent leakage of the fluid protruding from the fuel cell metal separator in the separator thickness direction, the method comprising the step of:\n at the time of trimming an outer marginal portion of the fuel cell metal separator or an inner marginal portion of the fluid passage, moving a trimming die from a side where the bead seal protrudes, in a direction opposite to a protruding direction of the bead seal.
