In this work, a pseudo-2D model including electrode reaction and membrane separation of the high-temperature electrochemical hydrogen pump (HT-EHP) was proposed to separate a CO-containing hydrogen mixture. Rigorous kinetics of electrochemical reaction and competitive adsorption was introduced to reach accurate performance prediction. The simulated polarization curves of three different feed gases, namely, no-CO and narrow and wide CO content ranges, at different temperatures were consistent with the experimental data (R 2 ≥ 0.90). Compared to previous work, the accuracy of the developed pseudo-2D model has been improved by 78.8% and 62.2%, respectively, under two feedstock conditions. Quantitative analysis of current density and catalyst coverage was achieved under various process conditions, demonstrating the applicability of HT-EHP pseudo-2D model. Feasible suggestions for the optimization design of HT-EHP were provided by analyzing the relationship between equipment scale, feed flow rate, current density and hydrogen recovery rate. Thus, the developed pseudo-2D model can be beneficial in the design and optimization of the HT-EHP system, and HT-EHP as an efficient membrane based technology is promising for the separation of CO-containing hydrogen mixtures in the future.

In this work, a partial element stage cut electrochemical hydrogen pump (EHP) model for multiple H2-contaning gases separation and hydrogen compression which embed real factors (anode impurity diffusion, hydrogen back-diffusion and anode catalyst deactivation) was established to study EHP performance accurately under full hydrogen concentration. The accuracy and reliability of proposed model were verified from four aspects (current density distribution, polarization curve, hydrogen recovery and purity) under different feedstock systems and wide pressure range. The model has good applicability and accuracy (R^2≥0.96, simulation and experiment results comparison). Simulation results show that high hydrogen back-diffusion ratio can cause low energy efficiency under high cathode pressure and low feedstock hydrogen content. The variation law of hydrogen purity under multi-operating conditions was studied, which shows dual-effect (PEM and GDL resistance) can affect hydrogen purity prominently through current density under low feedstock hydrogen content and applied potential.
