Abstract

Fast growing application of Proton Exchange Membrane (PEM) Fuel Cell in automotive industries, has brought the necessity of conducting research on automotive aspects of the fuel cell. In this study a medium size commercial PEM fuel cell is examined to observe the transient behavior of PEM fuel cells. The stack voltage transient is observed while the fuel cell undergoes step current loads and the time constant of the final transient process is calculated. The overall performance of the fuel cell is evaluated using standard ramp load experiment and the contribution of different type of voltage drops to the overall stack voltage is discussed.
