Abstract:

 The experimental research based on anode periodic exhaust and ampere-hour integral exhaust was made on laboratory-made air-cooled proton exchange membrane fuel cell (PEMFC). The effect of different target ampere-hour integral values on output stability was studied under high load, and the optimal target ampere-hour integral value was determined as 100As. The output performance and hydrogen consumption of two exhaust methods were investigated in the condition of varying load. Compared with periodic exhaust, ampere-hour integral exhaust saved almost 30% of hydrogen, for pretty much the same performance. As the high produce cost of hydrogen, the application of ampere-hour integral exhaust can also significantly reduce the engineering cost of PEMFC.

Key words: proton exchange membrane fuel cell (PEMFC), anode exhaust, ampere-hour integral, output performance, hydrogen consumption
