초록

Method for controlling the supply of air to a PROX reactor for the preferential oxidation in the presence of hydrogen wherein the concentration of the hydrogen entering and exiting the PROX reactor is monitored, the difference therebetween correlated to the amount of air needed to minimize such difference, and based thereon the air supply to the PROX reactor adjusted to provide such amount and minimize such difference.

In a method of operating a H2-O2 fuel cell system comprising the principle steps of (1) providing a hydrogen-rich fuel gas having a first carbon monoxide, CO, content sufficient to poison the fuel cell\s anode, and (2) subjecting said fuel gas to a preferential oxidation reaction for selectively oxidizing said CO with O2 in the presence of said hydrogen to produce a feed stream for said fuel cell which has a second carbon monoxide content less than said first content, the improvement comprising controlling the flow rate of said O2 to said preferential ox...
