Abstract
Ammonia gas is scrubbed from a gas stream in a bed of material soaked with acid, and the bed is regenerated by passing an oxygen containing gas therethrough. The preferred acid is phosphoric acid and the preferred support material is carbon in the form of porous particles. In a fuel cell system dual scrubbers alternately scrub ammonia from reform gas and are subsequently regenerated so as to provide the fuel cells with a continuous flow of substantially ammonia free hydrogen.
