Hydrogen is expected to be the clean and sustainable fuel as well as the most promising energy carrier. Water splitting using polymer electrolyte membrane have studied numerically and experimentally for producing hydrogen and oxygen by electrolysis in conjunction with intermittent renewable energies. In this study, a control-oriented model for polymer electrolyte membrane electrolyzer are developed to calculate mole balance and electrochemical reaction between at the anode and at the cathode. Numerical simulations are performed using MATLAB® and Simulink® software packages. The electrolyzer test station equipped with flow, temperature and power controllers are manufactured to evaluate the flow and temperature characteristics of circulating water, the uniformity of the pressure over the cell area, then enhance the performance of polymer electrolyte membrane electrolyzer. DC power supply can simulate experimentally the power of renewable energies. The numerical and experimental results are capable of characterizing the flow and temperature characteristics of circulating water and enhancing the performance of polymer electrolyte membrane electrolyzer, then developing the highly efficient control strategy. This polymer electrolyte membrane electrolyzer will be combined with polymer electrolyte membrane fuel cell to establish a regenerative fuel cell with the integrated control system.
