摘要： PURPOSE:To recycle the fuel electrode gas at the lower stream area of the passage in a simple method, by furnishing a throttle at the entrance of the fuel gas passage to speed up the gas flow, and absorbing the fuel electrode gas in the lower stream of the passage by the negative pressure effect. CONSTITUTION:A steam reforming catalyst 5 is filled at the fuel gas passage 4 contacting to fuel electrode 2, and at a nozzle 23 at the entrance of the fuel gas passage, a throttle 24 is arranged, to compose an inside reform type molten carbonate fuel cell. A hydrocarbon gas 11 is fed from a maniford 19 through the nozzle 23 to the fuel gas passage 4, and a generation is carried out under the presence of the reforming catalyst 5 by the cell reaction. At the same time, the flow speed is accelerated by the throttle 24 of the nozzle 23 to produce a negative pressure, and the fuel electrode gas 16 at the lower stream of the passage is absorbed thereby through the flow passages 26 and 25, and mixed at the throttle 24 to recycle. Therefore, the fuel gas can be reused readily with no blower, preheater and the like.

摘要： PURPOSE:To obtain a catalyst material having thin thickness, wide area, and high mechanical strength by constituting with a catalyst carrier of porous particles of metals oxide filled in the voids of nonwoven fabric and catalytic active material dispersed on the surface of the catalyst carrier. CONSTITUTION:A catalyst material is formed with metal oxide fibers 1, voids 3 of fiber nonwoven fabric, and metal oxide porous particles 2 filled in the voids. Metal oxide fibers or particles are partially sintered by baking at high temperature and its strength is increased. Peeling-off or coming-off of active material which occurs when metal core is used is prevented. In addition, if alkali metal oxide or its precursor is added before baking, fibers and particles form a complex oxide with alkali metal oxide to bind both materials strongly. Thereby, mechanical strength of a molding is increased even if it is thin and has wide area.

摘要： PURPOSE:To accelerate the filming speed while arresting ultrafine particles produced by photoexciting reaction effectively on the substrate by a method wherein both reaction gas feeding and substrate temperature are controlled synchronizing with laser beam irradiation. CONSTITUTION:A substrate 12 is loaded upon a stage 11 in a reaction chamber 28 while the temperature of stage 11 is controlled by an infrared ray lamp 40 and a coolant feeder 46. In order to accelerate the filming speed on the substrate 12, the substrate temperature is lowered synchronizing with laser beam irradiation. Then in order to increase the filming capacity on the substrate 12 as the next process, the substrate temperature is raised stepwise. Next reaction gas is fed from a nozzle 26 connected to a cylinder through the intermediary of flow rate controllers 20. In case of pulse laser beams, oscillating pulse signals are transmitted to the other controller 48 to control both temperature of substrate 12 and feeding of reaction gas synchronizing with the pulse signals. On the other hand, in case of continuously oscillating laser beams, a mechanism such as a chopper to transfer laser beams to pulses is provided to transmit the synchronized signals to the controller 48.

摘要： PURPOSE:To prevent the inside of a nozzle from choking due to coal-water slurry and obtain an adequate spray having small average particle diameters by a method wherein the coal-water slurry is adjusted to have specific viscosity. CONSTITUTION:Coal-water slurry L1 is passed through a preheater 4 via an open/close valve 2 and a pressure control valve 3 from a fuel supply pipe 5. At this time, the temperature of the coal-water slurry L1 is lower than that of the waterboiling point at the pressure of a mixing chamber 10, the temperature or the mixture containing the coal-water slurry in the mixing chamber 10 and water L2 supplied from a liquid supply pipe 9 is heated up to the setting temperature, and the heated coal-water slurry L1 is mixed in the mixing chamber 10 with the water L2 supplied from the liquid supply pipe 9. The turbulence generated in a flowing in the mixing chamber 10 by mixing the coal-water slurry L1 with the water L2 makes the flowability of the coal- water slurry L1 excellent. Further, the water L2 decreases the viscosity of the coal- water slurry L1 less than 1,500CP, and makes the flowability more excellent. The coal-water slurry given the excellent flowability in the mixing chamber 10 is passed through the nozzle 11, and at this time, the water is changed to a steam by the phase changing due to the rapid pressure changing of the coal-water slurry.

摘要： PROBLEM TO BE SOLVED: To provide an electrode catalyst for a fuel cell in which a metal cluster of which the metal circumference is covered by ligand is carried on a carbon carrier and which supersedes a performance of a conventional platinum catalyst without using expensive platinum. SOLUTION: A metal cluster containing a non-platinum group element is used for a catalyst active composition, and since the metal cluster has a metal of a different valence, it is possible to provide a catalyst having more improved electrode performance per cost of a used metal than a catalyst using platinum. By applying the catalyst for the electrode catalyst of the fuel cell, the fuel cell system of a low cost can be materialized without using expensive platinum as an active composition.
