Abstract
The dynamic performance of a single PEM fuel cell under load change condition is experimentally studied and the effect of oxygen stoichiometric flow rate and flow plate structure are analyzed. From the experiment results, it is found that, under the operating conditions in this paper, the control factors of cell dynamic performance are the membrane water content and liquid water transport process. The dynamic performance of fuel cell is increased with the increase of oxygen stoichiometric flow rate. For different flow plates studied in this paper, a relative better cell performance is found at small current density when parallel flow plate is used, and with the decrease of parallel channel number, the performance of the fuel cell is gradually decreased.
