Abstract:
1. A separator plate for a fuel cell comprising: a substrate disposed between a polymeric first flow field layer and a polymeric second flow field layer; wherein: the polymeric first flow field layer has a plurality of first and second channel walls extending along a length of the polymeric first flow field layer that defines a plurality of first reactant flow channels, the polymeric first flow field layer not having coolant flow channels; and the polymeric second flow field layer has a plurality of first channel walls and a plurality of second channel walls that form a plurality of second reactant flow channels, at least a portion of the first channel walls and the second channel walls of the polymeric second flow field layer further cooperating with the substrate to form coolant flow channels that are not in communication with the second reactant flow channels of the polymeric second flow field layer; wherein each of the channel walls extends from the substrate, the first and second channel walls of the polymeric second flow field interpenetrate each other at a plurality of junctions, and the first and second channel walls of the polymeric second flow field interpenetrate each other at a plurality of junctions.
