Abstract
Official abstract text for this publication.
Electrocatalyst layers include an electrocatalyst having high oxygen reduction activity that is useful as an alternative material to platinum catalysts. Uses of the electrocatalyst layers are also disclosed. The electrocatalyst layer includes an electrocatalyst that is formed of a metal oxide obtained by thermally decomposing a metal organic compound. The metal element forming the electrocatalyst is preferably one selected from the group consisting of niobium, titanium, tantalum and zirconium.
First claim
Opening claim text (preview).
1 . A process for production of an electrocatalyst layer comprising an electrocatalyst, the electrocatalyst comprising a metal oxide, and the process comprising a step of thermally decomposing a metal organic compound to give the metal oxide, wherein the metal element forming the metal organic compound is one selected from the group consisting of niobium, titanium, tantalum and zirconium; wherein the metal organic compound is one selected from the group consisting of metal alkoxides, metal carboxylates, metal amides and metal/β-diketone complexes; and wherein the thermally decomposing is performed at a temperature in the range of 500 to 1000° C. for 1 to 10 hours. 2 . The process according to claim 1 , wherein the metal element forming the metal organic compound is niobium or titanium. 3 . The process according to claim 1 , wherein the electrocatalyst is obtained by crushing the metal oxide.
