An experimental study on the dynamic process of PEM fuel cell stack voltage

Hou, Yongping; Yang, Zhihua; Fang, Xue - In: Renewable Energy 36 (2011) 1, pp. 325-329

The dynamic characteristics of the proton exchange membrane (PEM) fuel cell are of great importance in its design and applications. In this paper, the dynamic process of stack voltage is analyzed when the current is step inputted. We discuss the process from the following four aspects: voltage...
