Abstract
A method for ammonia decomposition is disclosed. The method may comprise providing a catalyst comprising an alumina support and a layer adjacent to the support. The layer comprises a perovskite phase comprising aluminum, cerium, and lanthanum, an oxide of at least one of an alkali metal and a rare earth metal, and an active metal. The method may comprise bringing the catalyst in contact with ammonia at a temperature of from about 400° C. to 700° C. to generate a reformate stream comprising hydrogen and nitrogen at an ammonia conversion efficiency of at least about 70%. The method may further comprise directing the hydrogen to a fuel cell to generate electricity. The method may further comprise generating heat for a reformer comprising the catalyst by combustion of gases or by electricity generated from hydrogen.
