| Abstract: | kW PEM fuel cell power system is used successfully as passenger car power engine. The influence of operation pressure of 40 kW PEM fuel cell power system on hydrogen fuel efficiency of whole power system was discussed, the influence of this power system operation pressure on PEM stack power output was also discussed. Experimental data show that the overall hydrogen fuel efficiency is 45%,if the PEM fuel cell power system operats under lower pressure (0.01 MPa, relative pressure); and the hydrogen fuel efficiency drops to 40%, if the PEM fuel cell power system operats under higher pressure (0.1 MPa, relative pressure). |
