摘要： PROBLEM TO BE SOLVED: To provide techniques to sufficiently maintain heat exchange efficiency during vaporization without requiring an increase in the size of an apparatus. SOLUTION: The apparatus has a steam mixing part 12 equipped with a honeycomb 13 having a concave face on its end face and with a nozzle 18 spraying water to the concave face. Since the end face of the honeycomb to be sprayed with water has a concave face, the water sprayed from the nozzle 18 is introduced into the honeycomb 13 in a uniform state. The water not entering the honeycomb 13 is rejected on the concave face and gathered in the center of the concave face, then led by the reformed gas supplied from the upstream side of the steam mixing part 12 to easily intrude into the honeycomb 13. The honeycomb 13 is heated by the high-temperature reformed gas passing through the honeycomb, the heat is exchanged between the cell walls of the honeycomb and water, and thus the water is vaporized and mixed with the reformed gas.

摘要： PROBLEM TO BE SOLVED: To provide a technology which allows for rapid pressure reduction of a leak detection passage in performing the leak detection of a shut-off valve on a fuel gas supply at a fuel cell system.
SOLUTION: A fuel cell system offers a normal mode and a gas leak detection mode. The system comprises a fuel cell; a fuel gas supply for supplying a fuel gas to the fuel cell; a shut-off valve which is attached in a passage for leading a fuel gas supplied from the fuel gas supply to the fuel cell and is able to shut off the fuel gas being supplied; and a variable pressure regulating valve which is attached in a passage between the shut-off valve and fuel cell, and performs pressure regulation so that a pressure of the fuel gas downstream in a supply direction of the fuel gas may become an adjustable pressure-regulating value. In the normal mode, the fuel cell system sets the pressure-regulating value of the variable pressure regulating valve to a normal power generation regulating value for performing the normal power generation. In the gas leak detection mode, the fuel cell system closes the shut-off valve, and sets the pressure-regulating value of the variable pressure regulating valve to the value higher than the normal power generation regulating value which is set up at the end of the normal mode for detection of fuel gas leak from the shut-off valve.

摘要： PROBLEM TO BE SOLVED: To provide a technology by which accuracy of leakage detection of a fuel gas can be improved in a fuel cell system. SOLUTION: In order to detect leakage of the fuel gas of the fuel cell system 100, firstly the hydrogen gas flow rate supplied in an anode gas supply passage 24 is detected, and the consumption volume of hydrogen gas consumed in the fuel cell 10 is calculated, and by subtracting the hydrogen gas consumption volume from the detected hydrogen flow rate, the differential gas volume is calculated. On the other hand, the pressure of fuel gas in a leak detection passage Cx is detected, and the change in the pressure of the detected fuel gas is obtained, and thereby the increased or decreased volume of the fuel gas flowed in the leak detection passage Cx occurring due to pressure change of the fuel gas is obtained. Then, by subtracting the obtained increased or decreased volume of the fuel gas from the calculated differential gas volume, the differential gas volume is corrected, and when it has a prescribed value or more, the leakage of the fuel gas is detected in the leakage detection passage Cx.
