All relevant data are within the paper. Abstract Because of the demands for sustainable and renewable energy, fuel cells have become increasingly popular, particularly the polymer electrolyte fuel cell PEFC.

PEM Fuel Cells

Among the various components, the cathode plays a key role in the operation of a PEFC. In this study, a quantitative dual-layer cathode model was proposed for determining the optimal parameters that minimize the over-potential difference and improve the efficiency using a newly developed bat swarm algorithm with a variable population embedded in the computational intelligence-aided design. The simulation results were in agreement with previously reported results, suggesting that the proposed technique has potential applications for automating and optimizing the design of PEFCs.

Introduction As a result of the increasing need for an efficient and clean energy supply, considerable importance has been placed on the advancement and fundamental research of polymer electrolyte fuel cell PEFC technology. Platinum Pt loading, ionic conductivity, and the reaction's exchange current density are among the factors that may affect the performance. Numerous studies have been conducted to develop models and approaches that are essential to battery performance and optimization.
