R, China Abstract: An electrochemical refrigeration and heating circulation system based on proton exchange membrane fuel cell (PEMFC) and electrolytic cell was presented. The working principle of the system was illustrated. The lumped parameter model of a PEMFC stack and a electrolytic cell have been developed and coupled into a dynamic model of system to evaluate influence of operating parameters on system operation efficiency and dynamic performance of refrigeration and heating. The results of simulation were validated with the experimental data from literature. Using the model, numerical study was performed to analyze the dynamic response of the system coefficient of performance, the input voltage of compensating power supply and the heating and refrigeration capability of the system to the step change of output current of fuel cell stack.
