PROTON CONDUCTIVE TITANATE, ITS MANUFACTURING METHOD, POLYMER NANO COMPOUND MEMBRANE CONTAINING THIS, AND FUEL CELL ADOPTING THIS

摘要

PPROBLEM TO BE SOLVED: To provide a proton conductive titanate, a polymer nano compound membrane containing this, and a fuel cell adopting the same. PSOLUTION: On the proton conductive titanate, titanate and sulfonic acid group-contained moiety having proton conductivity formed on the surface of the titanate are introduced. Sulfonic acid group-contained moiety having proton conductivity is directly bonded to titanate by ether-bonding. A polymer nano compound membrane containing this and a fuel cell adopting this are provided. PCOPYRIGHT: (C)2007,JPO&INPIT
