Abstract: Disclosed are a reversible fuel cell oxygen electrode in which IrO2 is electrodeposited and formed on a porous carbon material and platinum is applied thereon to form a porous platinum layer, a reversible fuel cell including the same, and a method for preparing the same. According to the corresponding reversible fuel cell oxygen electrode, as the loading amounts of IrO2 and platinum used in the reversible fuel cell oxygen electrode can be lowered, it is possible to exhibit excellent reversible fuel cell performances (excellent fuel cell performance and water electrolysis performance) by improving the mass transport of water and oxygen while being capable of reducing the loading amounts of IrO2 and platinum. Further, it is possible to exhibit a good activity of a catalyst when the present disclosure is applied to a reversible fuel cell oxygen electrode and to reduce corrosion of carbon.
