    摘要： A fuel cell system is provided including a fuel cell stack having a fuel cell having an anode, an anode outlet, an anode inlet, and a cathode. The fuel cell system further includes a hydrogen pump in communication with the anode outlet and the anode inlet. The hydrogen pump features a proton exchange membrane disposed between a first electrode and a second electrode. The first electrode is configured to accept an anode outlet stream from the anode outlet, the anode outlet stream including a hydrogen gas and an inert gas, the first electrode being configured to exhaust the inert gas. In one embodiment, the hydrogen pump is in communication with a PROX unit and configured to provide the hydrogen gas to the fuel cell stack. Further provided are methods employing the hydrogen pump wherein a start-stop degradation of the fuel cell is militated against and a hydrogen feed stream is humidified.

    摘要： A method for operating a fuel cell stack (10) for a fuel cell system, in particular of a vehicle, in which by reversing the flow direction (14, 16) of a coolant during a cooling operation, the coolant in the fuel cell stack (10) is initially conveyed in a first direction (14). The coolant is subsequently conveyed in a second direction (16) which is at least substantially opposite to the first direction (14). A time period, after the elapse of which the flow direction (14, 16) is reversed, is changed during the cooling operation. In addition, a distance at which a coolant volume is situated from a heat source (12) that is present in the fuel cell stack (10) may be changed during the cooling operation. The invention further relates to a fuel cell system.
