Patent ID: 10183428

Abstract:
A unit cell injection mold for fabricating a unit cell of a fuel cell, in which an integrated frame of the unit cell formed by injecting a polymer resin onto an insert, in which a membrane electrode assembly and a gas diffusion layer are integrated, is formed, the unit cell injection mold includes an upper mold, a lower mold engaged with the upper mold to define an inner space between the lower mold and the upper mold, the inner space including an injection area into which the insert is accommodated and an insert area into which the polymer resin is injected to form the frame, and elastic protrusions formed from an elastic material, the elastic protrusions being disposed on the upper mold and the lower mold to face each other, wherein the elastic protrusions clamp the insert to divide the inner space into the insert area and the injection area to prevent the polymer resin from entering the insert area.
