ABSTRACT
In this paper, the steady-state mathematical model of a single-cell Proton Exchange Membrane Fuel Cell (PEMFC) is derived from the electrochemical reactions. The governing equations are combined to form the overall single-cell PEMEC model using Matlab/Simulink. The experiments are conducted and the cell voltage, power, efficiency and humidity at various operating current levels are investigated and compared to the simulation results. The model has been validated against the obtained experimental results. It was found that the simulations results based on the presented model are consistent with the experimental results with minimal error.
Keywords: Single-cell PEMFC, Mathematical model, Humidity estimation, Model validation, Electrochemical relations.
