    摘要： A fuel cell system having a thermally integrated isothermal CO-cleansing subsystem including a water-gas-shift reactor, a preferential oxidation reactor, at least one system heat exchanger, and a closed-loop heat transfer circuit dedicated to that subsystem. The heat transfer circuit utilizes a heat transfer medium which has a high specific heat and is circulated through the circuit at a sufficiently high rate as to thermally dominate the gas stream components communicating with the circuit.

    摘要： An electrochemical engine for a vehicle comprises a fuel processor operating to process liquid fuel to hydrogen gas reformate, a combustor to generate heat for the fuel processor, and a fuel cell stack to generate electricity from the hydrogen gas reformate and producing water vapor by-product. A water management system of the engine comprises a condenser to reclaim liquid water from the water vapor by-product and a water tank for storing the reclaimed water. A water pump circulates water from the water tank to the fuel processor. A drainage valve is operable to open to release water from the water tank to a freeze tank to avoid freezing water in the water tank.

    摘要： Method of operating an autothermal reformer (ATR) to produce a high temperature reformate including preheating steam and air inputs to the ATR with heat from the reformate. The steam is heated by the reformate, and the air is then heated by the steam. There is no direct heat exchange between the reformate and the air. In the heat exchangers effecting the heat transfer, the steam is kept at a higher pressure that both the reformate and the air.
