A preferential oxidation reactor for a 10 kWe automotive PEM fuel cell system was developed. The reactor was designed as a dual-stage, multi-tube system. The performance was evaluated by feeding simulated gasoline reformate containing 1.2 wt % CO. The CO concentration of the treated performance was < 20 ppm at steady state and < 30 ppm at 65% load change. Hydrogen loss in the steady state was ∼1.5%, and the pressure drop across the reactor was 4 psi (0.3 bar). At startup the system takes 3 min to reduce the CO concentration to < 20 ppm, although several controllable factors could shorten this. This is an abstract of an article originally published in J. of Power sources 109(2) 394-402 (1 July 2002).
