A Proton Exchange Membrane Fuel Cell (PEMFC) system thermodynamic model including the main auxiliary components is developed. The system is composed of a PEMFC stack, heat exchanger, water tank, cooling pumps and inlet gases processing components (humidifier and compressor). A parametric study in terms of comparison on electric and thermal energy performances of fuel cell stack and total system are performed. A novel multiobjective evolutionary algorithm based on decomposition (MOEA/D) is introduced to optimize the operating parameters of the PEMFC system for the purpose of maximizing the system efficiency and power. The Pareto front, containing the set of optimal solutions for the system is obtained. The system energy efficiency and electric power at Final Optimal Point can reach 79% and 8.04 kW, respectively.
