To avoid degradation, the Proton Exchange Membrane (PEM) fuel cell requires less than 10 to 50 ppmv carbon monoxide (CO) in the reformate stream. A transient Preferential Oxidation (PrOx) system was developed for reformer operating powers between 5 kW and 60 kW thermal. Testing results show that steady state reformate CO concentration from the PrOx is less than 6 ppmv for a variety of inlet CO concentrations. Furthermore, the PrOx is capable of maintaining CO under 10 ppmv during reformer transient conditions such as power turn up and turn down.
