摘要： A partial oxidation reforming reaction occurs at the center of a chamber in a reformer, while a steam reforming reaction occurs in a localized manner around the chamber center. Thus, the efficiency of the reforming reaction is improved while keeping a temperature in the vicinity of an outer chamber wall low. Oxygen is supplied from an inlet center of the reformer so as to enhance a concentration of oxygen in a central area of the chamber. On the other hand, steam is supplied along an outer wall of the chamber so as to enhance a concentration of steam in an outer peripheral area of the chamber. When a hydrocarbon raw material is reformed in this state, a partial oxidation reforming reaction, which is an exothermic reaction, mainly occurs in the central area, while a steam reforming reaction, which is an endothermic reaction, tends to occur in the outer peripheral area surrounding the central area. Thus, in the central area, the partial oxidation reformation can be promoted by reaction heat that is generated. On the other hand, in the outer peripheral area, when the reaction heat produced in the central area diffuses, the reaction heat is absorbed so as to improve the efficiency of the steam reforming reaction while keeping a temperature of the vicinity of the outer wall low.
摘要翻译：部分氧化重整反应发生在重整器中的室的中心，而在室中央周围局部地发生蒸汽重整反应。因此，在保持外室壁附近的温度低的同时提高重整反应的效率。氧气从重整器的入口中心供应，以提高腔室中心区域的氧气浓度。另一方面，沿着室的外壁供应蒸汽，以增强室的外周区域中的蒸汽浓度。当在该状态下重整碳氢化合物原料时，作为放热反应的部分氧化重整反应主要发生在中心区域，而作为吸热反应的蒸气重整反应容易发生在外周区域周围中心区域。因此，在中心区域，可以通过产生的反应热促进部分氧化重整。另一方面，在外周区域，当在中心区域产生的反应热扩散时，反应热被吸收，从而提高蒸汽重整反应的效率，同时保持外壁附近的温度低。

摘要： The present invention provides a technique of reducing the concentration of carbon monoxide included in a hydrogen rich gas, which is fed as a supply of gaseous fuel to fuel cells. It is required that the activity of a carbon monoxide selective oxidation reaction for reducing the concentration of carbon monoxide is kept at a sufficiently high level in a wider temperature range. A CO selective oxidation unit 34, which reduces the concentration of carbon monoxide included in a hydrogen rich gas fed to fuel cells 20, has a carbon monoxide selective oxidation catalyst that includes a second element, such as lithium, in addition to ruthenium as a primary component. This arrangement enables the activity of the carbon monoxide selective oxidation reaction in the CO selective oxidation unit 34 to be kept at a sufficiently high level in a wider temperature range.

摘要： A carbon monoxide reducing device supplies oxygen to a reformate gas obtained through a reforming reaction so as to oxidize carbon monoxide contained in the reformate gas by means of the oxygen and thereby reduces a concentration of carbon monoxide contained in the reformate gas. This carbon monoxide reducing device is equipped with an oxygen supply amount controller designed to oxidize CO. The oxygen supply amount controller controls an amount of oxygen supplied to oxidize carbon monoxide contained in the reformate gas based on an amount of supply of fuel contributing to the reforming reaction. Thereby, the amount of oxygen for oxidizing carbon monoxide contained in the reformate gas is adjusted appropriately, and a high-quality reformate gas can be obtained.

摘要： The structure of the present invention consumes carbon monoxide produced by the reverse shift reaction proceeding in an effective temperature range that ensures a sufficient activity of a catalyst for selective oxidation of carbon monoxide, thus significantly reducing the concentration of carbon monoxide included in a resulting hydrogen-rich gas. A fuel reformer 30 incorporated in a fuel-cells system 10 includes a gas flow sensor 37 disposed in a reformed gas supply conduit 36 that connects a reformer unit 32 with a CO selective oxidizing unit 34. A control unit 70 outputs driving signals to three valves of the CO selective oxidizing unit 34, in response to a detection signal from the gas flow sensor 37. The CO selective oxidizing unit 34 has three reaction chambers filled with a carbon monoxide selective oxidizing catalyst. The number of the reaction chambers, which a reformed gas fed to the CO selective oxidizing unit 34 passes through, is changed by switching the on/off state of the three valves. This structure enables the amount of the carbon monoxide selective oxidizing catalyst to be regulated according to the flow rate of the reformed gas fed to the CO selective oxidizing unit 34.
