| 摘要 |
The invention relates to a fuel cell with integrated humidification, comprising a cathode-side or anode-side humidification unit with a heat exchanger (9,13), a condensate separator (10,14), a capillary tube (11,15) a nd a venturi nozzle and/or pump (12, 16). The invention also relates to a metho d for humidifying process gas for the operation of a fuel cell wherein only product water is used and wherein, according to a first embodiment, the gas containing 02 for the cathode is humidified by the cathode off-gas which contains water vapour by means of a first humidification unit and/or the combustion gas containing H2 for the anode is humidified by the anode off-ga s which contains water vapour by means of a second humidification unit or wherein, according to a second embodiment, the combustion gas containing H2 for the anode is humidified by the cathode off-gas which contains water vapo ur by means of a first humidification unit and/or the gas containing 02 for the cathode is humidified by the anode off-gas which contains water vapour by means of a second humidification unit. |
