▎ 摘　　要

NOVELTY - A composite corrosion-resistant fuel cell metal bipolar plate comprises metal thin plate and graphene film, where the graphene film is adhered to an outer surface of the metal thin plate to form a surface flexible graphite film metal sheet. USE - Composite corrosion-resistant fuel cell metal bipolar plate. ADVANTAGE - The composite corrosion-resistant fuel cell metal bipolar plate has enhanced fuel cell performance, prolonged service life, reduced contact resistance and corrosion rate and better utility value, in simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a composite corrosion-resistant fuel cell metal bipolar plate, which involves adhering a graphene film to a surface of a metal sheet to form thin metal composite panel with surface graphite film, punching out the metal composite plate with the graphene film adhered of the metal hydrogen plate and the metal oxygen plate, where the surface of the hydrogen plate has a hydrogen channel groove and a hydrogen cooling channel groove, and the surface of the oxygen plate has a hydrogen flow trench and oxygen cooling channel trench and connecting the hydrogen and oxygen plates into a bipolar plate to obtain the finished product.
