摘要： PROBLEM TO BE SOLVED: To obtain a catalytic combustion heater having a short starting time with safety for early activating an overall catalyst heat exchanger while preventing exhaust and ignition of unburned gas with a simple constitution. SOLUTION: A tube 2 having a fluid-to-be-heated channel therein is arranged in a fuel gas channel 11 containing combustible gas and combustion supporting gas, many fins 21 are provided on an outer periphery of the tube 2 to form an oxidizing catalyst layer on the surface. A temperature detector 7 for detecting a temperature of combustion exhaust gas is provided in an exhaust port 13 of the channel 11, and a flow controller 6 for controlling flow of the combustible gas at the time of starting based on the detected result is provided. The controller 6 controls to reduce a combustible gas flow until the exhaust gas temperature exceeds a predetermined temperature and judges the activation at part of the catalyst when exceeding the predetermined temperature to increase the combustible gas flow to a specified amount, thereby shortening a starting time while preventing ignition.

摘要： PURPOSE: To make a system compact, prevent the damage on an electrolyte film caused by contact of an atmosphere on an anode side with an atmosphere on a cathode side, and moisten a fuel gas. CONSTITUTION: A plurality of through holes 12 are formed in the direction of the film thickness of an electrolyte film 10. A gas shut-off layer 70 is formed between the electrolyte film 10 and an anode 20. Water produced in a cathode 30 is sent to the anode 20 side by a capillary action through the through holes 12 of the electrolyte film 10. Although an oxidizing gas taken in the cathode 30 passes through the through holes 12 together with the produced water, the oxidizing gas is completely shut out by the gas shut-out layer 70 and does not reach the anode 20. A fuel gas taken in the anode 20 is completely shut out by the gas shut-out layer 70 and does not enter the through holes 12.

摘要： PROBLEM TO BE SOLVED: To improve the heat exchanger efficiency of a catalytic combustion heater. SOLUTION: The catalytic combustion heater comprises fins 17B in boiling portions 31B for zoning the same into a plurality of small channels arranged perpendicularly to the surface thereof in Fig., which boiling portions are positioned in the midstream of a fluid-to-be-heated channel 3 contacting the intensively heated midstream portion 21B of a combustion gas channel 2 to boil the fluid to be heated. The fins 17B comprise through holes 170B for allowing adjacent small channels to communicate to each other, reducing pressure difference among the small channels to stabilize the surface of fluid and allowing bubbles expanding by bumping to escape to adjacent small channels so as to prevent the wall surfaces of the channels from being covered by gas layers poor in heat transfer efficiency, thereby allowing heat concentrated in the boiling portions 31B to be effectively transferred to the fluid to be heated.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating a combustion exhaust gas of a fuel reformer. SOLUTION: A control device 60 determines the valve opening of a flow control device 52 in accordance with the temperature of a cleaning device 40 detected via a temperature sensor 54. When the bulb opening of the flow control device 52 is determined, a flow rate of an anode off gas in proportion to the bulb opening is supplied to the cleaning device 40 via a supply pipe P5 of the anode off gas. In the cleaning device 40 containing unreacted hydrogen or unmodified fuel and the like, to which the anode off gas of a fuel cell has been supplied, the catalyst combustion of hydrogen and the like is accelerated by a catalyst 41 embedded within the cleaning device 40. The temperature of the catalyst 41 inside the cleaning device 40 is raised up to the activated temperature by the heat of reaction generated in according to the catalyst combustion of hydrogen and the like. Thus, the cleaned combustion exhaust gas is discharged from the cleaning device 40.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst for reducing carbon monoxide which can efficiently reduce carbon monoxide contained in reformed gas without deactivating the catalyst even when the temperature of a catalyst body is low during start-up and others and does not cause energy loss. SOLUTION: A carrier 42 comprising a substance of high conductivity is coated with a coat layer 44 in which water absorbing parts 44a comprising a water absorbing substance and water repelling parts 44b comprising a water repelling substance are arranged alternately in the gas flow direction. A noble metal catalyst 46 for oxidizing/removing carbon monoxide in reformed gas selectively is supported on the water repelling parts 44b or on the water repelling parts 44b and the water absorbing parts 44a to prepare a catalyst body 40 for reducing carbon monoxide. Water vapor in the reformed gas is condensed in the water absorbing parts 44a, and the water repelling parts 44b carrying the catalyst 46 are heated by the heat of condensation and heat of adsorption of the water vapor.
