Performance of Proton Exchange Membrane Fuel Cell Using Equivalent Electrical Equivalent Model

Abstract

Because of its simplicity, capability, high efficiency, quick start-up, is environmentally friendly
and has no geographical limitations, fuel cell is one of the most preferable renewable energy sources
nowadays. Proton Exchange Membrane Fuel Cell (PEMFC) is effective in transforming input energy into
electrical energy and has been viewed as a major potential source of energy for the future. Because of its
ability, there have been various trials and scientific studies in both the academic and industrial fields. Most
research has focused on the PEMFC steady-state analysis. Consideration of PEMFC reactions is also
relevant within this study. The PEMFC processes were implemented by modeling electrical models using
the simulation software Matlab / Simulink. The model was developed as two types of models that were
steady-state and dynamic model to provide a comparison of the charging-double layer capacitance (CDL)
and thermodynamic effect considerations. In addition to that, the models were modelled to develop a more
accurate model by following the actual stack specification of the 500-W PEMFC system manufactured by
Horizon Pte. Ltd. The performance of a PEMFC by a CDL using the electrical model are presented. The
model produced an efficiency output higher than 30% compared to the 40% H-500 PEMFC specification
efficiency which makes the model eligible for further development purposes.
