초록

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...
