Abstract
A bipolar plate for a fuel cell, having an anode side and a cathode side. The bipolar plate has two inactive supply regions, having anode gas channels which are each connected to one of two anode gas main channels and an anode gas flow field of an active region; cathode gas channels which are each connected to one of two cathode gas main channels and a cathode gas flow field of the active region; and coolant channels which are each connected to one of two coolant main channels and a coolant flow field of the active region. At least one of the anode gas main channels and the anode gas channels of the supply region connected thereto are arranged so that a length difference between a longest and a shortest anode gas channel of this supply region is at most 50% of the length of the longest anode gas channel.
