摘要： A method for fabricating a seal-integrated separator for a fuel cell is presented, with which seals can be accurately positioned and the assembling time for the fuel cells may be greatly reduced. The method comprises the steps of: providing an upper mold having a groove positioned corresponding to second and fourth seals disposed on one side of a separator body, and a lower mold having a groove positioned corresponding to first and third seals disposed on the other side of the separator body; holding the separator body between the upper mold and the lower mold; and injecting melted seal material to form the seals into each of the grooves in the upper mold and the lower mold through separate gates respectively formed in the upper and lower molds. Through this method, a seal-integrated separator having the first to fourth seals which are integrated on both sides of the separator body is fabricated.

摘要： A seal in a fuel cell for sealing a membrane electrode assembly comprises a pair of catalytic electrode layers, a polymerized electrolytic membrane held between the catalytic layers, and a gas diffusion layer layered on the outer surface of the catalytic electrode layer. The seal is integrally formed with the polymerized electrolytic membrane. The height thereof is greater than that of the gas diffusion layer. The difference between the heights of the polymerized electrolytic membrane and the gas diffusion layer is constant.

摘要： A method for fabricating a seal-integrated separator for a fuel cell is presented, with which seals can be accurately positioned and the assembling time for the fuel cell units may be greatly reduced. The method comprises the steps of: forming a through hole in the separator body; providing a first mold having grooves respectively positioned corresponding to the inner and outer seals disposed on one side of the separator body, a connecting cavity for forming a seal bridge at least partially connecting the inner and outer seals to each other at a position corresponding to the through hole, and at least one gate communicating with each of the grooves, and a second mold having grooves respectively positioned corresponding to the inner and outer seals disposed on the other side of the separator body, and a connecting cavity for forming a seal bridge at least partially connecting the inner and outer seals to each other at a position corresponding to the through hole; holding the separator body between the first mold and the second mold; and injecting melted seal material to form the seals into each of the grooves in the first mold by supplying the melted seal material into the gate and injecting a portion of the melted seal material into each of the grooves in the second mold via the through hole. Through this method, a seal-integrated separator having first to fourth seals which are integrated on both sides of the separator body is fabricated.
