Production of components for electrochemical cell assemblies

摘要

A process for the production of fuel cell or other electrochemical cell components in plate form in particular BIPOLAR plates comprises the following steps:

(a) treating a metal sheet to modify at least its interfacial resistance and/or corrosion resistance with respect to the fuel cell or other electrochemical cell environment; and

(b) following such treatment introducing features into the metal sheet in a repeating pattern by the application of mechanical force to the sheet; and

(c) dividing or separating the metal sheet into a plurality of individual plates each provided with a said feature or features.
