PROTON CONDUCTIVE MATERIAL, METHOD FOR PRODUCING PROTON CONDUCTIVE MATERIAL, MEMBRANE AND ELECTRODE ASSEMBLY AND FUEL CELL |
摘要 |
PROBLEM TO BE SOLVED: To provide a proton conductive material resistant to the elution of an acid component from the proton conductive material to a water-containing solution and free from the lowering of the ion conductive property. SOLUTION: The proton conductive material has an acid residue bonded to a main chain with covalent bond through a linking group and is crosslinked with two or more kinds of crosslinking groups. Particularly, the proton-conductive material has a main chain composed of carbon-carbon bond and contains a mesogen, a crosslinked structure having an Si-O bond and a crosslinked structure having a C-O bond or a C-C bond. The invention further provides a membrane and electrode assembly of the proton conductive material and its use in a fuel cell. COPYRIGHT: (C)2006,JPO&NCIPI
