Understanding how to control the different operating parameters in an electrochemical hydrogen compressor can provide a basis for further improving its performance. In this paper, the effects of hydrogen stoichiometric ratio:1.0-2.0, input temperature: 30-90 degrees C, inlet pressure: 30-90 kPa were systematically analyzed. Besides, we evaluate and discuss how various operating parameters and current densities affect the running performance, charge transfer, mass transfer, and kinetics of the hydrogen electrode reaction, using I-V curves and electrochemical impedance spectroscopy. Time and energy consumption are recorded at different voltages during the hydrogen compression process. For different actual needs, it is determined that 0.3 V is the best choice for a compression ratio of up to 22 in this system. We also analyze the causes and mechanisms of membrane electrode assembly deterioration and suggest improvements in the compression process and operation strategy.
