Abstract
A diagnostic method and method of controlling the preferential oxidation of CO in a reformed fuel gas stream includes periodically modulating the amount of air supplied to a preferential oxidation reactor at a specific operating characteristic of the fuel cell, such as power output or fuel flow rate, to determine the amount of air necessary to reduce the level of CO to an acceptable level.
