Abstract:

Progresses in hydrogen industry contributes to the goals of carbon peaking and carbon neutrality in China. Simultaneous equation modeling technique can be used to simulate the hydrogen production process by Proton Exchange Membrane(PEM). The variation of voltage, power and efficiency of the hydrogen production system with current density under different temperature, operating pressure and proton membrane thickness was studied. The model is optimized by iterative optimization. The results show that the highest working efficiency of the hydrogen production system under hydrogen safety constraints is 69.3 % with a cathode operating pressure at 0.728 MPa and a PEM thickness of 27.5 μm.

Key words: carbon neutrality, hydrogen energy, process simulation, proton exchange membrane(PEM), water electrolysis for produce hydrogen, integrated energy
