主权项

1. An electrode comprising:
a support; and a catalyst layer disposed on the support, the catalyst layer comprising a coated product of a composition comprising a dispersion medium, and polyoxazine-based compound particles uniformly dispersed in the dispersion medium wherein the dispersion medium comprises at least one material selected from the group consisting of alcohol, acids, and hydrocarbonic solvents, the acid comprising polyphosphoric acid, phosphonic acid (H3PO3), an organic phosphonic acid, pyro-phosphoric acid (H4P2O7), triphosphoric acid (H5P3O10) or meta-phosphoric acid, the hydrocarbonic solvent comprising N-methylpyrrolidine, dimethylacetamide, benzene or xylene, and the alcohol comprising ethanol; wherein the composition includes a catalyst selected from platinum or an alloy of platinum or a mixture of platinum and where the platinum utilization rate of the electrode is at least about 26%.
