Another Fuel Cell Operable in the intermediate temperature region (100 to 200 Celsius degree) was already developed. The fuel cell is a PEFC of the non-humidification type. A unique solid electrolyte membrane is used which is a PBI/H3PO4 composite membrane made of polybenzimidazole (PBI) doped with phosphoric acid. Possible applications of the technology are alkaline fuel cell, MFC and others, in addition to the PEFC.
Developer: Lab team led by Masahiro Rikukawa, professor of the Faculty of Science and Technology at Sophia University.
