An apparatus removes CO from a hydrogen-rich gas stream in a hydrogen fuel cell system. CO fouls costly catalytic particles in the membrane electrode assemblies. Both a catalyst adapted to perform a water gas shift reaction, and a carbon dioxide adsorbent are disposed in a rotating pressure swing adsorber housing. The adsorption of carbon dioxide shifts equilibrium toward carbon monoxide consumption. A second adsorbent may be disposed in the housing for adsorbing carbon monoxide at low temperatures, and is adapted to desorb carbon monoxide at high temper...
What is claimed is: 1. A method for removing carbon monoxide from a hydrogen-rich gas stream produced in a reactor, the method comprising: generating the hydrogen-rich gas stream in a first reactor at a first temperature, comprising one or more catalysts for conducting at least one of a stream reformation reaction, a partial oxidation reaction, or an autothermal reformation reaction of a hydrocarbon feed; passing the hydrogen-rich gas stream from the first reactor through a second reactor at a second temperature that is lower than said first temperature...
