    • A method of reducing the amount of carbon monoxide in process fuel gas in a feed stream for a fuel cell. The method includes introducing a hydrocarbon feed stream into a primary reactor and reacting the hydrocarbon feed stream in effective contact with a reforming catalyst forming primary reactor products containing hydrogen, carbon monoxide, carbon dioxide, and methane; placing a high activity water gas shift catalyst system into a water gas shift converter, introducing the primary reactor products into the water gas shift converter in effective contact with the high activity water gas shift catalyst system, and reacting the carbon monoxide and water to form carbon dioxide and hydrogen using a water gas shift reaction forming the feed stream for the fuel cell; and introducing the feed stream into the fuel cell. The high water gas shift catalyst system includes a noble metal, a support comprising a mixed metal oxide of cerium oxide and at least one of zirconium oxide or lanthanum oxide. A promoter of yttrium, an alkali metal, or alkaline earth metal can be included. A support dopant can also be included.
    • 一种在燃料电池的进料流中减少工艺燃料气体中的一氧化碳量的方法。 该方法包括将烃进料流引入初级反应器并使烃进料物流与形成含有氢气,一氧化碳,二氧化碳和甲烷的初级反应器产物的重整催化剂有效接触; 将高活性水煤气变换催化剂体系置于水煤气变换器中,将主反应器产物引入到与高活性水煤气变换催化剂体系有效接触的水煤气变换转化器中,并使一氧化碳与水反应形成碳 二氧化碳和氢气,使用形成燃料电池的进料流的水煤气变换反应; 并将进料流引入燃料电池。 高水煤气变换催化剂体系包括贵金属,包含氧化铈的混合金属氧化物和氧化锆或氧化镧中的至少一种的载体。 可以包括钇,碱金属或碱土金属的助催化剂。 也可以包括载体掺杂剂。
