Electrolyte membrane for fuel cells with a hydrogen peroxide generating catalyst and a hydrogen peroxide decomposing catalyst, and manufacturing processes therefor

摘要

The present disclosure relates to an electrolyte membrane for fuel cells comprising a hydrogen peroxide generating catalyst and a hydrogen peroxide decomposing catalyst, the electrolyte membrane having greatly improved durability, and a manufacturing method therefor. In particular, the electrolyte membrane has a carrier and a catalyst particle having a catalyst metal carried by the carrier, the catalyst metal containing one selected from the group consisting of a first metal having a catalyst activity for generating hydrogen peroxide, a second metal having a Catalyst activity for decomposing hydrogen peroxide, and a combination thereof.
