摘要： PURPOSE:To vary the externally recovered quantity of heat from a cell cooling water system according to the state on the side utilizing the heat in a fuel cell. CONSTITUTION:Heat transmission is conducted from a reforming gas supplied from a reformer 2 to a fuel cell body 1 to a cell cooling water system through a heat exchanger 12 for cell cooling water heating. A control device 14 controls a regulating valve 13 for cell cooling water heating on the basis of an external set signal of heat recovered quantity, whereby the heat transmitting quantity is controlled. Thus, the quantity of the heat recovered from the cell cooling water system to the outside through an exhaust heat recovering heat exchanger 4 can be varied according to the state on the side utilizing the recovered heat.

摘要： PURPOSE:To make safe operation of power generating continuously with a fuel cell even when it is not possible to perform the heat exhaust process with its exhaust heat processing device. CONSTITUTION:The output of a fuel cell is supplied through a cell output control device 12. If the exhaust heat collecting heat-exchanger 7 is not capable of exhausting the heat emitted by the body 1 of the fuel cell to the outside of the cell coolant system, a control device 5 measures the pressure in a stream separator 3 using a pressure sensor 6, controls the cell output control device 12 so that the pressure becomes constant, and decreases the amount of power generation of the fuel cell. This discreasing causes the heat emission amount at power generating to balance with the natural heat radiating, etc., makes constant the reacting temp. of the fuel cell, and permits continued operation of power generation while the heat exhaust process to outside the cell coolant system is no more needed.

摘要： PURPOSE:To regenerate refrigerant while satisfactorily holding vapor supplying pressure for regenerating the refrigerant and a temperature of cell coolant and to improve performance of an absorption type refrigerator by providing means such as an arrangement of a refrigerant regenerating tube of the refrigerator in a vapor separator for a fuel cell generator. CONSTITUTION:A main section of a fuel cell refrigerator integral system comprises a cell coolant cooling tube 3 for cooling a fuel cell 1, a vapor separator 13 for separating cell coolant of a vapor/liquid mixture state into vapor and warm water, and an absorption type refrigerator having a regenerator 16, a condenser 17, an absorber 18 and an evaporator 19. In this case, a refrigerant regenerating tube 26 of the refrigerator is arranged in the separator 13, and hence dilute absorption solution in an absorption type refrigerating cycle is regenerated by heat generated from the cell 1. A refrigerant separator 27 is provided thereby to separate it into refrigerant vapor regenerated in the tube 26 and concentrated absorption liquid. Thus, refrigerant regenerating temperature can be raised, and a temperature of the cell coolant can be maintained at an optimum value.

摘要： PURPOSE:To improve the refrigerating performance per steam quantity to be supplied by providing a condensed water exhausting quantity control means on the condensed water ring water pipeline of an absorbing type refrigerator. CONSTITUTION:The pressure signal of cell cooling water detected by a pressure detecting means 40 is inputted to a controller 42, and compared with a preliminarily inputted pressure set value of cell cooling water. The opening signal of a condensed water discharge quantity control valve 41 is outputted to eliminate the deviation between the cell cooling water pressure detected by the detecting means 40 and the pressure set value. Consequently, when the pressure of the cell cooling water is lowered, the opening of the control valve 41 is reduced to minimize the condensed water discharge quantity, and the effective condensation heat transfer area of a heat exchanger in the high temperature regenerator 22 of an absorbing type refrigerator is minimized by the condensed water of steam to raise the pressure of the cell cooling water. Contrary to this, when the pressure of the cell cooling water is raised, the opening of the valve 41 is increased, and consequently, the pressure of the cell cooling water is reduced.

摘要： PURPOSE:To continuously supply cell cooling water with stability so as to stably recover exhaust heat when the discharged heat is recovered while a temperature or pressure of the cell cooling water is kept to be constant in a fuel cell power generating system where steam generated from the cell cooling water is used for reformation of fuel. CONSTITUTION:A generated current detector 30 measures a generated current of a fuel cell 3, and inputs the result into a controller 32 which calculates a quantity of steam required for fuel reformation. An engine speed controller 31 controls a cell cooling water supplying pump 10 at an engine speed, at which cell cooling water according to the steam quantity can be supplied. Accordingly, the cell cooling water can be continuously supplied with stability. Consequently, it is possible to keep a temperature or pressure of the cell cooling water constant so as to stably recover exhaust heat from the cell cooling water.

CONSTITUTION:Exhaust gas generated in a fuel cell body 1 is sent to an exhaust gas heat exchanger 10 so that heat is recovered, and the heat of exhaust gas generated in a reformer 2 is recovered by means of an exhaust gas heat exchanger 11. Exchangers 10 and 11 are connected to a condenser 6, and the gas from which heat is recovered is condensed further by means of the condenser 6, and is released into the air, and water generated at this time is sent to a water treatment device 7, and is used as a part of cooling water. The first blowdown circuit 8 is connected upstream of the heat exchanger 11 through a three way directional control valve 12 from a steam separator 5, and on the other hand, the three way directional control valve 12 is connected to the second blowdown circuit 13, and this second blowdown circuit is connected downstream of the heat exchangers 10 and 11 as well as upstream of the condenser 6, and the directional control valve 12 is controlled by means of a controller 15 according to operation of a sensor 14 so as to switch the circuits 8 and 13.

摘要： PURPOSE:To control a temperature of exhaust gas getting into a condenser for a fuel cell to be lower than a temperature at which fleon refrigerant is decomposed in the condenser for the fuel cell which recovers condensed water from exhaust gas of the fuel cell using the fleon refirgerant. CONSTITUTION:A condenser 20 for a fuel cell for recovering condensed water from exhaust gas of a fuel cell 2 is provided in an exhaust passage for the fuel cell 2, and this condenser 20 for the fuel cell is provided with an exhaust gas intake port, an exhaust gas cooling air intake port, and an exhaust gas cooling air intake port opening/closing plate 22. This exhaust gas cooling air intake port opening/closing plate 22 is opened and closed based on a temperature of the exhaust gas flowing into the condenser 20 for the fuel cell by a shape memory alloy 21 which transforms at a lower temperature than a temperature at which fleon refrigerant 25 is decomposed, and it is cooled by mixing intake air when the temperature is high, thereby the temperature of the exhaust gas is prevented from being more than set value.

摘要： PURPOSE:To trap mist produced during welding a branch pipe connecting socket to a low pressure pipe, by providing a leaf spring attached thereto with a heat- insulatable and air-permeable cloth, at the distal end of a retaining rod fitted in an insertion unit. CONSTITUTION:A socket fixing nipple 15 is screwed into a female thread 2 formed in a low pressure pipe 1, a socket 20 is fitted onto the nipple 15, and an insertion unit 25 is fitted in the socket 20. A substantially circular leaf spring 37 attached thereto with an insulatable and air-permeable cloth is rotatably attached to the distal end of a retaining rod 33 fitted in the insertion unit 25. With this arrangement, mist produced by the decomposition of epoxy resin applied to the interior of the low pressure pipe, due to heat generated during welding of the socket 20 to the low pressure pipe 1, can be trapped by the cloth 38. Further, the mist which passing through the cloth 38 without being trapped therein is emitted outside from the insertion unit 25, being carried by the stream of gas.
