HYPER-BRANCHED POLYMER, ELECTRODE FOR FUEL CELL INCLUDING THE HYPER-BRANCHED POLYMER, ELECTROLYTE MEMBRANE FOR FUEL CELL INCLUDING THE HYPER-BRANCHED POLYMER, AND FUEL CELL INCLUDING AT LEAST ONE OF THE ELECTRODE AND THE ELECTROLYTE MEMBRANE

摘要

A hyper-branched polymer having a degree of branching in the range of about 0.05 to about 1 includes a dendritic unit, a linear unit, and a terminal unit, wherein the hyper-branched polymer, an electrode for a fuel cell including the hyper-branched polymer, an electrolyte membrane for a fuel cell including the hyper-branched polymer, and a fuel cell including at least one of the electrode and the electrolyte membrane. Such a hyper-branched polymer included in a fuel cell provides excellent thermal resistance and phosphoric acid resistance and increase the performance of the fuel cell.
