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.
Claims19
A method of manufacturing a membrane electrode assembly, comprising:
- preparing a catalyst composite by drying a mixture comprising a catalyst and a first binder;
- applying a catalyst admixture comprising the catalyst composite and a second binder to a first surface of a porous substrate to form a first electrode;
- and
- forming a second electrode on a second surface of the porous substrate, and
- wherein the first binder is fixed or partially attached to the catalyst.
