Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A perovskite compound represented by Formula 1: [A n Pd (1-n) ][B][X] 3 (1) wherein A is a metal other than palladium, B is selected from nitrogen, phosphorus, sulfuric acid, boron, carbon, and oxygen, X is identical to or different from A and is a metal other than palladium, and n is a real number satisfying 0≤n<1, and wherein n in Formula 1 is a real number satisfying 0.1≤n<0.5. 2. The perovskite compound according to claim 1 , wherein each of A and X in Formula 1 is independently selected from nickel, cobalt, copper, iron, vanadium, chromium, manganese, and zinc.
