Monitoring of the Anode Dry out at High Current Censity in H2/O2 and H2/air PEMFC Stack

The polymer electrolyte fuel cell (PEFC) is of great interest in energy research because of its high efficiency, high power density, low pollution and low operating temperature But they have to overcome some engineering and economic problems in order to be a commercial success. In particular, humidification is accompanied by energy loss. Hence, operation under optimal humidified conditions is of great advantage for improved energy conversion efficiency.
