Patent ID: 7491355

Claim:
A method for fabricating a seal-integrated separator for a fuel cell, said seal-integrated separator including a separator body and an inner seal and an outer seal which are integrated on both sides of said separator body and which are disposed, side by side, around an electrode's reaction surface during use, comprising the steps of: forming a through hole in said separator body; providing a first mold having grooves respectively positioned corresponding to said inner and outer seals disposed on a first side of said separator body, a connecting cavity for forming a seal bridge at least partially connecting said inner and outer seals to each other at a position corresponding to said through hole, and at least one gate communicating with each of said grooves, and a second mold having grooves respectively positioned corresponding to said inner and outer seals disposed on a second side of said separator body, and a connecting cavity for forming a seal bridge at least partially connecting said inner and outer seals to each other at a position corresponding to said through hole; holding said separator body between said first mold and said second mold; and injecting melted seal material to form said seals into each of said grooves in said first mold by supplying said melted seal material into said gate and injecting a portion of said melted seal material into each of said grooves in said second mold via said through hole, so that said inner and outer seals are formed adjacent to each other on the first side of said separator body, said inner and outer seals are formed adjacent to each other on the second side of said separator body, and said inner and outer seals formed on the first side of said separator body and said inner and outer seals formed on the second side of said separator body are formed at symmetrical positions about said separator body.
