Abstract
This study introduces the experimental results of a high-temperature electrochemical hydrogen purification (ECHP) cell through poly 2.2-m-phenylene-5.5-bibenzimidazole/metal organic framework (PBI/MOF) composite membranes in the temperature range of 140°C-180°C. Synthesis of ZIF-8 and UiO-66 MOFs was conducted through a typical solvothermal method, and composite membranes containing 2.5 wt. %. MOF was fabricated. Experiments were conducted with pure hydrogen (H2) and reformate gas mixtures containing H2, carbon monoxide (CO), and carbon dioxide (CO2). A gas chromatography device (GC) was used to analyze the gas composition at the exit of the ECHP cell. The final output H2 purity was found to be >99.9 % for the H2/CO2/CO mixed-phase and >99.7% for the H2/CO mixed phase. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
