| 摘要 |
The present invention relates to a cathode catalyst of a polymer electrolyte fuel cell and a method for manufacturing the same and, more specifically, to a cathode catalyst of a polymer electrolyte fuel cell including a carbon nanotube-graphene composite immersed with titanium nitride (TiN), and a method for manufacturing the same. The cathode catalyst of a polymer electrolyte fuel cell according to the present invention is cheap in price, stable, and has a high reduction capacity, at the same time having a high activity in both onset potential and current during an oxygen reduction reaction occurring in the cathode of the polymer electrolyte fuel cell, thus can be effectively utilized as a cathode of the polymer electrolyte fuel cell. Moreover, the manufacturing process of the catalyst is simple. The catalyst manufactured according to the present invention can be effectively used as a cathode catalyst of a polymer electrolyte fuel cell adapted to power sources at home and transportations such as automobiles. |
