  • Patent number: 11522200
    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.
    Type: Grant

  • Patent number: 11214497
    Abstract: Disclosed are a perovskite compound, a method for producing the perovskite compound, a catalyst for a fuel cell including the perovskite compound, and a method for producing the catalyst. The perovskite compound overcomes the low stability of palladium due to its perovskite structural properties. Therefore, the perovskite compound can be used as a catalyst material for a fuel cell. In addition, the use of palladium in the catalyst instead of expensive platinum leads to an improvement in the price competitiveness of fuel cells. The catalyst is highly durable and catalytically active due to its perovskite structure.
