Fuel cell with pre-shaped current collectors

摘要

The present invention discloses a process for manufacturing a fuel cell and an associated fuel cell array that includes novel pre-shaped current collectors and conforming compression plates. The current collectors are pre-shaped to counteract any deflection of the fuel cell after compression is released during manufacture. The pre-shaped current collectors may bend outwards by the same amount as previously, however, the overall compression relaxation may be much lower because the pre-shaped current collectors are bending back into the flat position, as opposed to away from it. Also provided with the present invention are associated mold plates that induce the desired pre-shaping to the current collectors.
