Patent ID: 7049233

Claim:
A method for manufacturing a thin film electrode of ruthenium oxide comprises the steps of: preparing a precursor solution that is a heterogeneous solvent (RuC13·x H2O) mixed is ethanol, introducing said precursor solution into an injector ( 2 ) for spraying process, heating a substrate by a halogen lamp ( 6 ) for maintaining a temperature of 50–400° C. to process an electronic aerosol spray pyrolysis (EASP), forming a strong electrical field between a substrate-supporting base and said injector to generate electrically charged nano-size of very fine particles by connecting said substrate-supporting base and said injector ( 2 ) through a direct current power supply, spraying said precursor solution on said heated substrate to deposit said nano-sized very fine partices by influence of electrically charged particles actions; and treating said electrode deposited substrate for pyrolyzing about 100–600° C., about 2 to 24 hours under oxygen included gas atmosphere.
