ELECTRODE COMPRISING ORGANIC FUNCTIONAL METAL OXIDE, MANUFACTURING METHOD THEREFOR, MEMBRANE-ELECTRODE ASSEMBLY COMPRISING SAME, AND FUEL CELL COMPRISING MEMBRANE-ELECTRODE ASSEMBLY

The present invention relates to an electrode comprising organic functional metal oxides, a manufacturing method thereof, a membrane-electrode assembly including the same, and a fuel cell including the membrane-electrode assembly, and the electrode comprises a support, catalyst particles supported on the support, organic functional metal oxide nanoparticles supported on the support, and an ionomer positioned on the surface of the support. The electrode improves catalyst performance and durability in a high voltage range, can reduce the amount of a catalyst used and catalyst costs by enabling excellent current density and power density to be obtained even in a state that a relatively small amount of the catalyst is used through an increase in catalyst utilization and uniform dispersion of the catalyst, and improves performance in general and low humidification conditions.
