Abstract
Disclosed is a method of manufacturing a membrane electrode assembly with minimized interfacial resistance between an electrode and an electrolyte membrane. For instance, a catalyst admixture including a catalyst composite including a catalyst and a first binder, and a second binder may be applied to a porous substrate and the porous substrate may be impregnated with the second binder, thereby minimizing interfacial resistance between the electrode and the electrolyte membrane and reducing a thickness of the electrolyte membrane.
