Abstract:
An electrolyte membrane made of a phosphate-containing siloxane-based polymer for fuel cell, where the polymer comprises a siloxane backbone and a poly(meth)acrylate chain to which phosphate groups are attached, and the polymer is formed by vinyl polymerization of a silane compound having a (meth)acrylate functional group or a hydrolysis-polycondensation product thereof and a (meth)acrylate compound having a phosphate group, followed by siloxane crosslinking. The electrolyte membrane of a siloxane-based polymer has a high conductivity for a fuel cell.
