Abstract:Summary
In the present work, the purification of hydrogen from a hydrogen/carbon dioxide/carbon monoxide (H2:CO2:CO) mixture by a high‐temperature electrochemical purification (HT‐ECHP) system is examined. Electrochemical H2 purification experiments were carried out in the temperature range of 140‐180°C. The effects of the molar ratio of the gases in the mixture (H2:CO2:CO‐75:25:0, H2:CO2:CO‐72:26:2,0 H2:CO2:CO‐75:22:3, H2:CO2:CO‐75:20:5, H2:CO2:CO‐97:0:3, H2:CO2:CO‐95:0:5) and the operating temperature on the… Show more
“…The lower activation energy of Cu-BTC-Lys (43 wt%) falls within the energy range of the Grotthuss proton migration pathway, which involves proton hopping along formed hydrogen-bonding networks. 40,41 On the other hand, the other samples primarily followed the vehicle mechanism due to the limited Lys proton donors in the frameworks. The possible proton hopping routes are presented in Fig.…”
To meet the growing demand for clean and sustainable energy, the development of high-performance proton conductive materials is crucial for practical applications in PEMFCs. However, current materials suffer from issues...
