Original Abstract Submitted

A bipolar plate for a fuel cell having a two-phase cooling system and a fuel cell system includes a coolant inlet, a coolant outlet, and coolant channels with the coolant inlet being in fluid connection with the coolant outlet via the coolant channels. At least one inner surface of coolant inlet, coolant outlet and at least one of the coolant channels has a surface treatment to influence a flow regime of a cooling fluid along at least one inner surface and/or a phase transition of the cooling fluid.
