A proton exchange membrane fuel cell system includes a proton exchange membrane fuel cell; a first compressor for compressing the process air supplied to the fuel cell; a first expander coupled with compressor for driving the first compressor; and a catalytic burner as the heat source. The cathode offgas from the fuel cell is fed to the catalytic burner as an air supply and the expander is operated by the exhaust air from the catalytic burner. A portion of the gas from the burner is expanded in a second expander, which is coupled to a second compressor w...
[ What is claimed is:] [1.] A method for operating a proton exchange membrane fuel cell system, comprising:generating a combustion gas comprising hydrogen and carbon monoxide in a gas-generating system;guiding the hydrogen into a proton membrane fuel cell;compressing air with a first compressor;supplying the compressed air to the proton exchange member fuel cell, thereby producing a cathode offgas and anode offgas;supplying the cathode offgas to a catalytic burner as an air supply, thereby producing exhaust air;expanding the exhaust air with a first expa...
