Thermodynamic and exergoeconomic analyses of a vehicular fuel cell power system with waste heat recovery for cabin heating and reactants preheating

In this paper, a novel vehicular proton exchange membrane fuel cell power system with waste heat recovery for multiple thermal applications is proposed. The utilized cabin heating and reactants preheating. Thermodynamic model of the proposed established validated. evaluated from viewpoints thermodynamic exergoeconomic. results show that possible amount supplied to varies 933 W 23971 by adjustment operating parameters. Energy consumption exergy destruction each component are presented, components should receive more priority in further researches pointed out. effects operation parameters on energy efficiency, efficiency total cost per unit product presented analyzed parametric studies. It found first increases then decrease as stack temperature increased. Single-objective multi-objective optimizations better economic performance conducted. By optimizing parameters, could be increased 45.77%, decreased 29.42 US$/GJ.
