Abstract:
In a fuel cell assembly (100, 200), a diffusion layer (113, 114, 201) comprises an electroconductive film (133, 133a, 133b) formed integrally with a separator (115, 116, 115a) so as to form a unitary separator-diffusion layer assembly (130, 131, 130a, 203). The electroconductive film of the diffusion layer can be formed on the separator by a process comprising physical vapor deposition, chemical vapor deposition, spin coating, sputtering or screen printing.
