Reversible fuel cell oxygen electrode reversible fuel cell including the same and method for preparing the same

摘要

Disclosed is a reversible fuel cell oxygen electrode comprising a porous carbon material formed by electrolytic plating of IrO ₂ and platinum applied thereto to form a porous platinum layer, and a reversible fuel cell comprising the same. According to the reversible fuel cell oxygen electrode, since the amount of IrO ₂ and platinum loading used in the reversible fuel cell oxygen electrode can be lowered, it is possible to reduce the amount of precious metal used while improving the mass transfer of water and oxygen, (Excellent fuel cell performance and water electrolysis performance). In addition, when applied to a reversible fuel cell oxygen electrode, it can exhibit good catalytic activity and reduce carbon corrosion. In addition, the manufacturing process is very simple compared to the conventional one, and the manufacturing cost can be greatly reduced.
