Simulator of a PEM fuel-cell stack based on a dynamic model

This paper presents a low cost, easy to use digital simulator for a proton exchange membrane fuel-cell (PEMFC) stack by means of a power source controlled by LabVIEW. The simulator easily allows to implement different models and simultaneously permits to study different FC types. The FC stack is represented with a circuital model that considers the capacitive effects of the electrodes and the internal thermodynamic characteristics. Experimental results are contrasted with the data model from a Relion SR-12 500-W PEM FC stack.
