<p>A method and apparatus oxidizes the carbon monoxide present in an incoming reactant fuel stream and/or carbon monoxide produced by the reverse water-shift reaction to carbon dioxide in a reactant stream introduced to an electrochemical fuel cell. The reactant stream comprises hydrogen, carbon dioxide and carbon monoxide. A first oxygen-containing gas stream is introduced into the reactant stream through a first port disposed between the reactant stream inlet (214) and the reactant stream outlet (218). A further oxygen-containing gas stream is introduced into the reactant stream through at least one secondary port (234) located between the first port and the reactant stream outlet (218).</p> |
