ELECTROCHEMICAL FUEL CELL STACK

摘要

The invention relates to an electrochemical fuel cell stack comprising a membrane-electrode-unit and a distributor plate comprising a channel area with gas channels for distributing anode or cathode gas to the membrane-electrode-unit, a portal area for supplying anode and/or cathode gas into the channel area and a portal area for removing anode and/or cathode gas from the channel area. According to the invention, the gas channels in the channel area of the distributor plate are not combined in a bundle but are disentangled and distributed over on a plurality of separated channel regions. A gas channel extends exactly in a channel region, with at least one deviation between the portal areas for supplying and removing anode and/or cathode gas.
