| 摘要 |
The invention relates to a fuel cell stack with gaseous fuel, comprising a membrane electrode unit (8) and a distribution sheet (1), comprising a channel region (2) with gas channels (3) for the distribution of the anode or cathode gases the membrane electrode unit (8) and a port region (4) for introduction of the anode and cathode gas into the channel region (2). According to the invention, additional connection channels (6) from the port regions (4) open out along the gas channels (3) such that unused anode or cathode gas from the port regions (4) may be locally dosed into the gas channels (3) by means of said connection channels (6). |
