Abstract

Dynamic current characteristics in a PEM fuel cell with a single channel serpentine flow field are measured by using a technique of current density distribution measurement gasket and a multi-channel potentiostat. The transient responses of the local currents and average current density in the PEM fuel cell to humidification temperature and fuel cell temperature are studied as well. The experimental results show that the transient response of local currents is far more complicated than that of average current density, and the responses of local currents to humidification temperature and fuel cell temperature at different locations are very different. When the fuel cell temperature increases from a low temperature to a high temperature, different response characteristics in local currents are observed. It is showed in this paper that the dynamic characteristics of local currents in PEM fuel cell are more complicated than those of average current density.
