Patent ID: 7682409

Claim:
A method of manufacturing a wave-shaped current collector of a fuel cell, comprising: providing an anti-corrosion and anti-oxidation charge-collecting layer; covering a first side of said charge-collecting layer with a masking layer; plating a conductive layer on a second side of said charge-collecting layer; forming a photosensitive dry film on said conductive layer, wherein said photosensitive dry film defines a pattern of said current collector; etching away said conductive layer that is not covered with said photosensitive dry film; removing said photosensitive dry film and said masking layer; adhering a protection film on said second side of said charge-collecting layer to isolate said conductive layer; performing a cutting process to form a current collector; and stamping said current collector to form a wave-shaped current collector, thereby defining a plurality of flow channels thereon.
