BIPOLARE PLATTE ZUR VERWENDUNG IN EINER BRENNSTOFFZELLE MIT POLYMERELEKTRODEN

摘要

At least one of a conductive metallic inclusion of carbide and boride protrudes through the outer surface of passive film from stainless steel under the passive film. An independent claim is included for the production of the stainless steel product by corroding the product surface using an aqueous acidic solution to expose at least one of a conductive metallic inclusion of boride or carbide on the surface, neutralizing using an aqueous alkaline solution having a pH of 7 or more, then washing and drying.
