Abstract
A bipolar plate for a fuel cell, including a profiled anode plate and a profiled cathode plate, each having an active region and two distribution regions for feeding and discharging operating media to and from the active region, and each distribution region having a main anode-gas port for supplying and evacuating fuel, a main cathode-gas port for supplying and evacuating oxidant and a main coolant port for supplying and evacuating coolant, the ports being arranged along a lateral edge of the bipolar plate. The plates are stacked so that the bipolar plate has channels interconnecting the main operating media ports of both distribution regions, and the distribution regions have at least one overlapping section, in which the channels overlap such that they do not form fluidic connections. A fuel cell is also provided. The main cathode-gas port is arranged between the main anode-gas port and the main coolant port and, starting from the main cathode-gas port, cathode channels run rectilinearly at least over the distribution region of the bipolar plate.
