A FC stack performance depends on the behavior of each single cell. Non uniformity in the voltage of the cells can be caused by components/manufacturing problems or operating problems such as a non adequate reactants distribution, water flooding or dehydration. To analyze the effect of different control strategies on cell voltage non uniformity at the Mechanical Engineering Department of the University of Trieste a test rig has been developed. The stack currently analyzed is a 47 PEM cell stack manufactured by Ballard. The uniformity analysis has been performed at different loads investigating the effect of different control strategies regarding anode purge and cathode air flow rate.

Abstract

A FC stack performance depends on the behavior of each single cell. Non uniformity in the voltage of the cells can be caused by components/manufacturing problems or operating problems such as a non adequate reactants distribution, water flooding or dehydration. To analyze the effect of different control strategies on cell voltage non uniformity at the Mechanical Engineering Department of the University of Trieste a test rig has been developed. The stack currently analyzed is a 47 PEM cell stack manufactured by Ballard. The uniformity analysis has been performed at different loads investigating the effect of different control strategies regarding anode purge and cathode air flow rate.
