Abstract:
A fluid flow plate for a fuel cell assembly, said fuel cell assembly having a longitudinal axis, said fluid flow plate extending generally transversely with respect to said longitudinal axis, said fluid flow plate comprising:a plurality of first conductive fibers located in a section of said fluid flow plate, said first conductive fibers having a number of spaces therebetween;a plurality of second conductive fibers;metal foil located between said first conductive fibers and said second conductive fibers;said first and second conductive fibers and said metal foil comprising at least one electrical path extending effectively in parallel with said longitudinal axis, said at least one electrical path adapted to conduct electrical current generated by said fuel cell assembly;rigidizing material including a portion positioned in at least one of said spaces, said rigidizing material having a relatively low density; andsaid section including a flow channel adapted to service at least one fluid for said fuel cell assembly.
