FUEL CELL METAL SEPARATOR AND POWER GENERATION CELL

Abstract:

A first metal separator includes a seal bead protruding from a base plate. The seal bead includes a curved section having a curved shape in a plan view of the first metal separator. The combination of the radius of curvature and the angle of the curved section is set within a specific zone where variation in a seal surface pressure in a direction in which the seal bead extends is suppressed.
