摘要： PURPOSE: To provide a method of preventing corrosion by accurately detecting the condition of corrosion of buried pipes, by making a buried pipe-earth potential measurement using the current interrupter method and at the same by making a measurement of a current density flowing from or into the buried pipe.
CONSTITUTION: When probe 10 and buried pipe 1 are connected by means of lead line 11, current i consisting of anti-corrosion current 6 and stray current 8 flows into probe 10. When probe 10 and buried pipe 1 is disconnected by means of current interrupter 12, current i flowing into probe 10 can be cut completely. For this reason, it is possible to measure the true probe-to-earth potential, excluding iR, by the current interrupter method. Also, when the current flowing between probe 10 and buried pipe 1 is measured by ammeter 13, it is possible to obtain the current density flowing from or into probe 10.

摘要翻译：目的：提供一种通过精确检测埋管腐蚀状况来防止腐蚀的方法，通过使用电流断流器方法进行埋地管电位测量，并通过对流过或流入的电流密度进行测量埋管。构成：当探头10和埋管1通过引线11连接时，由防腐蚀电流6和杂散电流8组成的电流i流入探头10.当探头10和埋管1通过电流断路器断开时如图12所示，流入探针10的电流i可以被完全切断。因此，可以通过当前的断续方法测量除iR之外的真实探头对地电位。此外，当通过电流表13测量探头10和埋管1之间流动的电流时，可以获得从探头10流入的电流密度。

摘要： PROBLEM TO BE SOLVED: To obtain a detection method for leakage hydrogen, in which the leaked hydrogen is changed into a substance having an odor, without preliminarily adding an odorizer to hydrogen so as to detect its leakage simply and surely and to obtain a detection apparatus for the leaked hydrogen. SOLUTION: In the detection method for the leaked hydrogen as the detection method for the leaked hydrogen, the leakage hydrogen is detected, in such a way that a nongaseous odor substance and a substance having a catalytic action with reference to the nongaseous odor substance and the hydrogen are made to coexist and that a substance having a gaseous odor is generated, when the leaked hydrogen comes into contact with the nongaseous odor substance. The detection apparatus for the leaked hydrogen is formed, in such a way that the nongaseous odor substance and the substance having the catalytic action with reference to the nongaseous odor substance, and the hydrogen are made to coexist on a support and that the substance having the gaseous odor is generated, when the leaked hydrogen comes into contact with the surface of the nongaseous odor substance.

摘要： PROBLEM TO BE SOLVED: To decrease a S/C ratio (the ratio of steam amount to carbon amount in fuel) in a reformer and increase a hydrogen utilization factor for a fuel cell, while preventing the poisoning of the fuel cell, for improving generating efficiency. SOLUTION: This generator has a reformer 12 in which unburn material in exhaust gas 7 is burned to form a heat source and material is reformed into reformed gas containing hydrogen, a shift converter 14 to reduce CO concentration in the reformed gas with shift reaction to form anode gas 6 for a fuel cell, the fuel cell 16 for generation with anode gas containing hydrogen and cathode gas 9 containing oxygen and a steam spray 18 to spray steam into the reformed gas 5b. An S/C ratio in the reformer 12 is decreased for operation and steam is sprayed into the reformed gas to reduce CO concentration at the exit of the shift converter. A material utilization factor for the fuel cell is increased.

摘要： PROBLEM TO BE SOLVED: To provide a phosphoric acid fuel cell device in which a dead space between apparatuses is eliminated to make a whole package compact by structuring a desulfurizer, a modifying unit and a CO transformer a plate form and placing a modifying unit so that it is held between other apparatuses. SOLUTION: A desulfurizer 11, a modifying unit 12 and a CO transformer 17 are structured in a plate form on the same plane. The desulfurizer 11, the molifying unit 12 and the CO transformer 17 are laminated in this order from the bottom. A lower modifying part 13 and an upper catalyzer burning part 14 are partitioned in the modifying unit 12, and modifying catalyzer 15 and burning catalyzer 16 are filled in them respectively. A lower CO transformer cooling side 18 and an upper CO transformer modifying side 19 are partitioned in the CO transformer 17. An alumina ball 21 is filled in the upstream side of the CO transformer modifying side 18 and an alumina ball 20 is filled in the lower stream side of the CO transformer cooling side 18. The alumina ball 21 suppresses its temperature at a low level by means of heat exchange with reacting gas from the modifying part 13.

摘要： PROBLEM TO BE SOLVED: To prevent increase in concentration of CO in a returning part, increase hydrogen concentration to prevent voltage drop, and enhance the durability of a cell by installing a second shift converter in the returning part of an anode side gas flow path communicating with an anode outlet from an anode inlet constituted as a meandering flow path having the returning part. SOLUTION: An anode side flow path A of a cell 1 of a phosphoric acid fuel cell is connected to an inlet 2a of a first shift converter 2, and an outlet 2b is connected to an anode 1a of the cell 1. The cell 1 is connected to an inlet 4a of a meandering flow path 4 which is a returning part of the anode side flow path A, an outlet 4b of the meandering flow path 4 is connected to the cell 1 through an inlet 3a and an outlet 3b of a second shift converter 3, and communicated with an anode outlet 1b. By the action of the second shift converter 3, the concentration of CO is decreased, and voltage drop caused by CO poisoning of a catalyst is prevented.
