Abstract
A bipolar plate () for making a proton-exchange membrane fuel cell stack, said bipolar plate () being made up of metal sheets that are shaped and assembled together in such a manner as to define primary fluid-flow channels () and secondary fluid-flow channels () that are arranged in alternation, said primary channels () being formed between said assembled-together sheets; the bipolar plate () being characterized in that it includes mechanical reinforcement () made out of metal material arranged in a reinforcing duct () of the bipolar plate (), said metal reinforcement () being configured in such a manner as to oppose a compression force applied to the bipolar plate (), said bipolar plate () further including a source of electricity adapted to feed electric current to the mechanical reinforcement () and thereby give off heat by the Joule effect.
