ABSTRACT:
A fuel cell sub-assembly having a cathode current collector, a cathode electrode, an electrolyte matrix, an anode electrode and an anode current collector arranged in a sandwich construction and provided with a plurality of rows of dimples. Adjacent rows of dimples extend in opposite directions from the sandwich construction and separator plates also with rows of dimples are arranged adjacent to the sandwich construction so as to form therewith channels for the fuel and oxidant gases. Also disclosed are unique separator plate configurations.
