Abstract
An embodiment method of manufacturing a titanium oxide-based support for a fuel cell includes preparing a sol-gel solution by mixing a titanium precursor and an ammonium-based pore control agent, preparing an ultrasonic spray solution by mixing the sol-gel solution and a transition metal precursor, allowing the ultrasonic spray solution to react by ultrasonic spray pyrolysis, and obtaining a final product by calcining a result obtained after completion of reaction.
