KORROSIONSBESTÄNDIGE BESCHICHTETE BRENNSTOFFZELLE BIPOLARE PLATTE MIT EINER SCHUTZSCHICHT AUS GRAPHIT UND VERFAHREN ZUR HERSTELLUNG

摘要

A corrosion resistant coated fuel cell plate and method of making the same are embodied in a metal plate provided with a graphite emulsion coating and then a layer of graphite foil which is pressed over the coating. The graphite emulsion bonds the graphite foil to the metal plate and seals fine scale porosities in the graphite foil. Flow fields are formed by stamping the coated fuel cell plate.
