  • Maintaining oxygen/carbon ratio with temperature controlled valve
    Publication number: 20050282096
    Abstract: Fuel from a source (6) passes through a hydrogen desulfurizer (8) and a proportioning mixing valve (10) to a CPO (31), the temperature of the output of the CPO being monitored (50) to provide a signal (51) which a controller (52) utilizes to adjust the valve (10). The output of the CPO may be passed through a water gas shift reactor (35) and a preferential CO oxidizer (40) to provide fuel to a fuel cell system (26). The air provided to the valve (10) may be humidified, such as by an enthalpy recovery device (21) receiving the oxidant outflow (24) from the fuel cell system.
