Abstract

A fuel cell having an anode-cathode stack includes at least one active surface layer formed by a first channel structure with a first and at least one second channel for conducting a first fluid over the at least one active surface layer of the anode-cathode stack. A first distributor structure for distributing the first fluid into the first and the at least one second channel of the channel structure is provided. The first distributor structure is configured with a first surface region assigned to the first channel and with a second surface region assigned to the second channel. The two surface regions are configured with a flow resistance of differing magnitude for the first fluid distributed in the first distributor structure.
