ABSTRACT:
An electrochemical fuel cell stack includes a membrane electrode assembly and a distributor plate. The distributor plate includes a channel region having gas channels for distributing reaction gas to the membrane electrode assembly, a first port area for supplying reaction gas to the channel region, and a second port area for removing reaction gas from the channel region. The gas channels are disentangled and each distributed in a respective separate channel area, at least one of the gas channels having at least one deflection point between the first and second port areas.
