| 摘要 |
A fuel cell system comprising a plurality of fuel cells combined together to form a fuel cell stack, with the fuel cell stack having an anode side with an inlet for a fuel and an outlet for non-consumed fuel and exhaust gases arising at the anode side as well as a cathode side with an inlet for a gaseous oxidising agent such as air and an outlet for exhaust gases which arise at the cathode side, and a compressor having a compressor inlet and a compressor outlet, the compressor outlet of which is connected to the oxidising agent inlet of the fuel cell stack provided at the cathode side, is characterised in that a gas dynamic pressure wave machine having a driven rotor is provided, with an inlet for exhaust gases arising at the cathode side, an inlet for fresh oxidizing agent, an outlet for oxidising agent compressed by the cathode side exhaust gases and also an outlet for the cathode side exhaust gases being associated with the rotor and with the outlet for the oxidising agent compressed by the cathode side exhaust gases being connected upstream of the input of the compressor.
