Abstract
The invention relates to an electrochemical fuel cell stack, comprising at least one membrane-electrode unit (MEA) consisting of an anode, a cathode and an electrolyte membrane which is located between them, at least one gas distributor structure on the anode side, comprising an anode gas inlet area, an anode gas outlet area and channels for guiding the anode gas from the anode gas inlet area to the anode gas outlet area, said anode gas containing hydrogen and being un-wet or partially wet; at least one gas distributor structure on the cathode side, comprising a cathode gas inlet area, a cathode gas outlet area and channels for guiding the cathode gas from the cathode gas inlet area to the cathode gas outlet area, the cathode gas containing oxygen and being un-wet or partially wet; and a coolant distributor structure, comprising a coolant inlet area, a coolant outlet area and channels for guiding the coolant from the coolant inlet area to the coolant outlet area. According to the invention, the coolant inlet area and the cathode gas inlet area overlap each other at least partially. The coolant outlet area and the cathode gas outlet area also overlap each other at least partially, so that a temperature gradient with a temperature that increases from the inlet area to the outlet area can form along the coolant and cathode gas channels between the overlap areas in inlet and outlet areas.
