Proton Exchange Membrane Fuel Cell (PEMFC) Modeling for High Efficiency Fuel Cell Balance of Plant (BOP)

摘要

In this paper, an informative PEMFC stack modeling is performed in order to provide a platform to optimal design of EBOP and MBOP for fuel cell systems. It is explained by the structure and operating principle of the PEMFC for the modeling. The open circuit voltage of the PEMFC is derived by the Gibbs free energy and Nernst equation. Numerical equations are derived to express three polarizations with the function of pressure and flow rate of hydrogen and air. The simulator is made of the mathematical modeling of the PEMFC and is verified by simulation and experimental results.
