Synthesis of ceramics/polymer nanocomposites protonic conducting membrane for fuelcells application

摘要

High temperature protonic conducting polymer membrane provides new technological applications in the electrochemical devices including electrochromic displays, chemical sensors, fuel cells and others. Organic/inorganic nanocomposites membrane consists of SiO{sub}2 /PEO (Polyethylene Oxides) hybrid are remarkable family. of isotropic, amorphous polymer materials, which has been synthesized through solgel processes. The hybrid membrane doped with acidic surfactant molecules shows good protonic conductivities at high temperatures above looC. The membrane was found to be thermally stable at high temperatures because of the inorganic SiO{sub}2 framework in the composites matrix.
