ELECTRODE ADDITIVE FOR FUEL CELL AND ITS SYNTHESIS METHOD

摘要

Disclosed is an electrode additive for a fuel cell and a synthesis method thereof. A synthesis method according to an exemplary embodiment of the present invention includes: producing a metal salt solution by dissolving metal salt in a solvent such as ethylene glycol; producing a carbon-metal salt suspension by distributing carbon in the metal salt solution; heating and cooling the carbon-metal salt suspension and then filtering out the carbon-supported metal powder; cleansing and drying the carbon-supported metal powder; and obtaining carbon-supported metal oxide powder by performing heat treatment on the carbon-supported metal powder at about 300-1000° C. by exposure to water vapor.

主权项

1. A synthesis method of an electrode additive for a fuel cell, the method comprising:
producing a metal salt solution by dissolving at least one metal salt in ethylene glycol; producing a carbon-metal salt suspension by distributing carbon in the metal salt solution; heating and then subsequently cooling the carbon-metal salt suspension; filtering, cleansing, and drying carbon-supported metal powder; and obtaining carbon-supported metal oxide powder by performing heat treatment on the carbon-supported metal powder at about 300-1000° C. by supplying water vapor.
