Abstract

The present disclosure relates to an electrolyte membrane for membrane-electrode assemblies and a method of manufacturing the same. The electrolyte membrane contains a catalyst including a hollow nanoparticle having a polyhedral framework. Specifically, the electrolyte membrane includes an electrolyte layer including a proton conductive ionomer and a catalyst dispersed in the electrolyte layer, wherein the catalyst includes a hollow nanoparticle having a polyhedral framework.

Description

technical field [0001] The present disclosure relates to an electrolyte membrane for a membrane-electrode assembly, including a catalyst including hollow nanoparticles having a polyhedral framework, and a method of manufacturing the same. Background technique [0002] In a polymer electrolyte membrane fuel cell (PEMFC), an electrolyte membrane is used to conduct hydrogen ions. Electrolyte membranes are fabricated using ion exchange materials in order to transfer hydrogen ions. The ion exchange material includes moisture in order to selectively move hydrogen ions generated at the negative electrode to the positive electrode. [0003] Due to the crossover of hydrogen, the electrolyte membrane deteriorates, so that the durability of the electrolyte membrane decreases. Due to the cross movement of hydrogen, hydrogen contacts oxygen at the interface between the electrolyte membrane and the positive electrode, thereby generating hydrogen peroxide. Hydrogen peroxide decomposes i...
