Patent number: 12206143Abstract: The present disclosure relates to a composite electrolyte membrane and a method of manufacturing the same. A catalyst composite layer in the composite electrolyte membrane uniformly includes a catalyst and an antioxidant, whereby it is possible to inhibit generation of hydrogen peroxide by side reaction. In addition, the catalyst composite layer is formed as a separate layer, whereby the catalyst composite layer is instead degraded, greatly inhibiting membrane degradation even in the case in which radicals attack an ionomer due to small side reaction. Furthermore, it is possible to control the position of the catalyst composite layer including the catalyst and the antioxidant by adjusting the thicknesses of a second ion exchange layer and the catalyst composite layer, whereby it is possible to protect a specific degradation position, and therefore it is possible to efficiently improve membrane durability.Type: GrantFiled: September 8, 2021Date of Patent: January 21, 2025Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Hee Jin Woo, Min Kyung Kim
