Fuel cell stack

摘要

A fuel cell stack having gaseous fuel is described, comprising a membrane electrode unit (8) and a distribution plate (1) including a channel area (2) having gas channels (3) for distributing the anode gas and the cathode gas to the membrane electrode unit (8) and a port area (4) for supplying the anode gas and the cathode gas into the channel area (2). Additional connecting channels (6) discharge from the port areas (4) along the gas channels (3) so that unused anode gas or cathode gas is locally meterable from the port areas (4) into the gas channels (3) via these connecting channels (6).
