Document Type and Number:
WIPO Patent Application WO/2023/243902
Kind Code:
A1
Abstract:
Provided is a membrane-electrode assembly, of which both performance and durability are improved. An embodiment of the present invention provides a membrane-electrode assembly comprising a polymer electrolyte membrane and a catalyst layer disposed on at least one surface of the polymer electrolyte membrane, wherein the catalyst layer comprises platelet mesoporous carbon having a short-axis pore form and has no metal nanoparticles supported thereon, the catalyst layer being a single layer.
