FUEL CELL, IN PARTICULAR FOR ARRANGEMENT IN A FUEL CELL STACK, AND FUEL CELL STACK

摘要

The invention relates to a fuel cell (1), in particular for arrangement in a fuel cell stack, having a first bipolar plate (2) and a second bipolar plate (3) and having a membrane electrode assembly (4), which is arranged between the two bipolar plates (2, 3) arranged plane-parallel to one another, an anode flow field (F1) being formed between the first bipolar plate (2) and the membrane electrode assembly (4) and a cathode flow field (F1) being formed between the second bipolar plate (3) and the membrane electrode assembly (4) by channel structures respectively with anode channels (K1) and cathode channels (K2) introduced respectively into the first bipolar plate (2) and the second bipolar plate (3), and the membrane electrode assembly (4) comprising at least one opening (8), which introduces some of the anode waste gas from the flow outlet side of the anode flow field (F1) into a cathode gas on the flow inlet side of the cathode flow field (F2). According to the invention at least one sequence element (9) is arranged in the region of the opening (8) and controls discharge of some of the anode waste gas into the cathode gas.
