Electrochemical hydrogen separation and compression using polybenzimidazole (PBI) fuel cell technology / Magnus Thomassen in Journal of natural gas science and engineering, Vol. 2 N° 5 (Novembre 2010)  

Public ISBD [article]  inJournal of natural gas science and engineering > Vol. 2 N° 5 (Novembre 2010) . - pp. 229–234 Titre : Electrochemical hydrogen separation and compression using polybenzimidazole (PBI) fuel cell technology Type de document : texte imprimé Auteurs : Magnus Thomassen, Auteur ; Edel Sheridan, Auteur ; Jannicke Kvello, Auteur Année de publication : 2012 Article en page(s) : pp. 229–234 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Hydrogen pump Separation and compression Polymer electrolyte membrane fuel cell (PEMFC) Phosphoric acid-doped polybenzimidazole (PBI) Résumé : Simultaneous hydrogen separation and compression using high-temperature (>100 °C) PEM fuel cell technology (PBI) was demonstrated for pure hydrogen, nitrogen/hydrogen mixtures and reformate feed gas mixtures containing various amounts of CO, CO2 and CH4. Gas purity measurements of the separated gas were performed and significant reductions in impurities were achieved. The effects of hydrogen concentration, inlet gas humidification, operating temperature and air bleed on the cell performance were studied and hydrogen diffusion through the polybenzimidazole membrane was measured. The hydrogen separation required relatively low energy consumption and demonstrated good dynamic response. Simultaneous separation and compression of hydrogen up to 0.65 barg was demonstrated.
