Effects of Operating Parameters and Loading Modes on the Dynamic Cell Performance of PEM Fuel Cells

Abstract:

This paper experimentally investigates the dynamic response of a single fuel cell under various dynamic loadings with different operating conditions. Three kinds of loadings are applied to the PEM fuel cell and they are simulated NEDC mode, simulated 10/15 mode, and modified mode. The operating conditions are set at different cell temperatures, humidification temperatures, and stoichiometric rates during each test to study the effects of these parameters on the cell performance of a PEM fuel cell. The cell performance is found increased with increasing cell temperature in the range of 45-65°C. On the other hand, there exist optimal conditions for the humidification temperature and the stoichiometric rate at 70°C/60°C and 1.5/2.0 on the anode and cathode sides, respectively.
