초록

An apparatus removes carbon monoxide (CO) from a hydrogen-rich gas stream in a hydrogen fuel cell system. CO fouls costly catalytic particles in the membrane electrode assemblies of proton exchange membrane (PEM) fuel cells. A vessel houses a carbon monoxide adsorbent. The vessel may be a rotating pressure swing adsorber. A water gas shift reactor is upstream of the rotating pressure swing adsorber. The water gas shift reactor may include a second adsorbent adapted to adsorb carbon monoxide at low temperatures and to desorb carbon monoxide at high temper...

청구항

What is claimed is: 1. A method for improving the quality of a hydrogen-containing gas stream comprising: producing a first gas stream having a hydrogen content and a carbon monoxide content in a first reactor; passing said first gas stream through a shift reactor to produce an effluent stream, said shift reactor including a first reaction region having a water gas shift catalyst and a second reaction region having a first carbon monoxide adsorbent; adsorbing said carbon monoxide content from said first gas stream in said second reaction region when sai...
