Experimental validation of a PEM fuel cell dynamic model

The adoption of fuel cells (FCs) for industrial, transportation and home power generation applications is widely increased during recent years. To better design these kind of applications, a FC model is required, in order to evaluate the performance at different working conditions. For transportation and variable speed drive applications the dynamic response to a variable power request is one of the most important parameters; a dynamic model describing the FC behaviour is then desired. To this aim in this paper we propose a dynamic model of a stack of PEM (polymer electrolyte membrane) fuel cells, which has been validated through experimental measures
