Abstract

This contribution deals with thermal modelling and experimental analysis of the air-cooled PEM (Proton Ex-change Membrane) fuel cell for power systems of transportation applications. The technology of the energy conversion which directly converts chemical energy of the fuel (hydrogen fuel) into electrical energy presents a potential replacement for the conventional internal combustion engine (ICE) in transportation applications. This paper explores the limits of using the air cooling for Polymer Electrolyte Membrane (PEM) stacks. In the present study, a numerical thermal model is presented in order to analyse the heat transfer and predict the temperature distribution in air-cooled PEM fuel cells. In order to validate the performance of the created analytical simulation model, comparisons of the data obtained through experimental measurements in the Fuel Cells laboratory have been made.
