Experimental Research on the Proton Exchange Membrane Fuel Cell Waste Heat Recovery System

The proton exchange membrane fuel cell combined heat and power (PEMFC-CHP) system can exploit the thermal energy and the electrical energy simultaneously, and the comprehensive utilization of energy efficiency is improved. The PEMFC-CHP system is considered as a promising low-carbon technology. Due to the strict requirements on the use and storage of the hydrogen, most of the current research on the PEMFC-CHP system is based on the simulation, and the experimental validation of the research on the waste heat recovery in the PEMFC-CHP system is limited. Therefore, a simulation experiment platform of the PEMFC waste heat recovery system is proposed in this paper. The PEMFC output characteristics and the thermal management methodology are analyzed. A control strategy of the PEMFC waste heat recovery system is proposed. Finally, the effectiveness of the control strategy is validated on the simulation experiment platform built.
