Abstract
The present disclosure is a method for manufacturing a catalyst for a fuel cell using the blood of slaughtered livestock. The method for manufacturing a catalyst for a fuel cell using the blood of slaughtered livestock of the present disclosure allows preparation of a catalyst for a fuel cell exhibiting high redox reaction activity and very superior durability as compared to a commercially available platinum catalyst through a very simple process of purification of the blood of slaughtered livestock and hydrothermal synthesis. In addition, the method is very economical in that a catalyst is prepared using the pure blood of livestock only without an artificial additive, waste disposal cost can be reduced by recycling the blood of livestock and a high-performance catalyst capable of replacing the expensive platinum catalyst can be prepared.
