It is generally agreed that such coatings must be conductive and adhere to the metallic bipolar plate substrate [33, 34, 80]. Proper adhesion to the substrate is achieved by careful selection of coating materials having thermal expansion coefficients similar to those of the substrate to minimize micro- and macrocrack formation.
