摘要:
Hydrogen-rich reformed gas is produced by reaction including partial oxidation of feed gas in a reforming reaction section (6). In this case, for the purpose of reducing temperature variations in the reforming reaction section (6), improving the thermal efficiency thereof and providing a reformer (A) with a simple and compact construction, the reformer (A) is formed in a double-wall structure consisting of a housing (1) and partitions (2), (2) inside of the housing (1), the reforming reaction section (6) is contained between the partitions (2), (2), and a feed gas passage (3) is provided by the space between the housing (1) and the partition (2). In this manner, the feed gas passage (3) is provided in the surrounding area of the reforming reaction section (6). The reforming reaction section (6) is thermally insulated by the feed gas passage (3) so that temperature variations in the reforming reaction section (6) can be reduced. The feed gas in the feed gas passage (3) is preheated by heat of reaction in the reforming reaction section (6) so that the self-recovery of heat can improve thermal efficiency of the reformer (A). In addition, a preheater for preheating the feed gas can be formed integrally between the feed gas passage (3) and the reforming reaction section (6) thereby compacting the construction of the reformer.
摘要:
Shift conversion of hydrogen-rich reformed gas produced by reaction including partial oxidation of feed gas in a reforming reaction section (6) is made by its water gas shift reaction with shift conversion catalyst in a shift reaction section (10) in order to reduce CO contained in the reformed gas and enhance the yield of hydrogen. In this case, for the purpose of enabling high-temperature reformed gas from the reforming reaction section (6) to undergo the shift conversion as it is and thereby simplifying the construction of a shift conversion unit, the reformed gas from the reforming reaction section (6) is introduced directly into a reformed gas passage (11) of the shift reaction section (10) and thereby undergoes the shift reaction while heat-exchanging with the feed gas.

When humidifying, almost to water vapor saturation, reformed gas that is supplied to a hydrogen electrode of a solid polymer type fuel cell (1) and air that is supplied to an oxygen electrode of the fuel cell (1), heating for obtaining water vapor to establish such saturation is not required. For the purpose of improving the thermal efficiency of a fuel cell system, water vapor contained in hydrogen electrode exhaust gas exhausted from the hydrogen electrode of the fuel cell (1) is let to penetrate through a water vapor permeable membrane (34), whereas water vapor contained either in air that is introduced into a partial oxidation reformation section (6) or in oxygen electrode exhaust gas exhausted from the oxygen electrode is let to penetrate through the water vapor permeable membrane (34) so that the water vapor is supplied to air that is supplied to the oxygen electrode of the fuel cell (1).

Placed in a fuel reformer (5) is a catalyst (27) which exhibits an activity to the partial oxidation reaction of a source fuel. The source fuel, oxygen, and steam are supplied to the fuel reformer (5) such that the ratio O2/C, i.e., the ratio of the number of moles of the oxygen to the number of moles of carbon of the source fuel, is not less than 0.9 times the O2/C theoretical mixture ratio in the partial oxidation reaction, and the H2O/C ratio, i.e., the ratio of the number of moles of the steam to the number of the source fuel carbon moles is not less than 0.5, wherein the partial oxidation reaction occurs in the catalyst (27) to cause a water gas shift reaction to take place in which CO produced by the partial oxidation reaction is a reactant, for generation of hydrogen.

摘要:
A humidity controller apparatus (20) contains an adsorption rotor (24) and a heater (25). A first passage (21) along which a first air stream flows and a second passage (22) along which a second air stream flows are formed in the humidity controller apparatus (20). The amount of heat exchange between the first and second air streams and the amount of moisture exchange between the first and second air streams vary by adjustment to the rotating speed of the adsorption rotor (24), and the humidity controller apparatus (20) is switched between a dehumidification operation and a humidification/heating operation. During the dehumidification operation, the rotating speed of the adsorption rotor (24) is set low. The first air stream is dehumidified by the adsorption rotor (24) and then supplied to the inside of a room. The second air stream is used for regeneration of the adsorption rotor (24) and then discharged to the outside of the room. During the humidification/heating operation, the rotating speed of the adsorption rotor (24) is set high. The first air stream receives heat and moisture from the adsorption rotor (24) and then is supplied to the inside of the room. The second air stream is heat/moisture-adsorbed by the adsorption rotor (24) and then discharged to the outside of the room.

An air conditioning apparatus is provided which includes a plurality of heat exchangers (11, 12, 13) for effecting heat exchange between a heating medium (such as refrigerant, cold and hot water et cetera) and air and which is adapted to separately perform sensible heat processing and latent heat processing of room air (RA). In the air conditioning apparatus, at least one heat exchanger (13) is made up of an adsorption heat exchanger (13) that supports on its surface an adsorbent, thereby preventing the increase in apparatus size and making it possible to perform operations at high COP.
