摘要： PROBLEM TO BE SOLVED: To follow the load change while suppressing the frequent changes, and to prevent the flowing of reverse current to the another system power supplies. SOLUTION: When the operation mode, to which the power consumption of a load 16 detected by a load wattmeter 58 belongs, becomes a different thing from the operation mode set up now, by resetting a timer, the operation mode is changed into the operation mode, to which the power consumption belongs when the state has been maintained for a predetermined time. When the output electric power from an inverter 54 exceeds the power consumption detected by the load wattmeter 58 by the time that a predetermined time to change the operation mode has progressed, the inverter 54 is controlled so that the output electric power from the inverter 54 may coincidence with the power consumption of the load 16. Consequently, while being able to control the frequent change of the operation mode, it can follow the load change, and the reverse current flow to the commercial power supply 10 from the system can be prevented.

摘要： PROBLEM TO BE SOLVED: To reduce the influence to the operation, when the output voltage of a fuel cell drops. SOLUTION: An electronic control unit of a fuel cell power generation system reads the output voltage Vfc (S200), the voltage drop degree ΔV is calculated (S210), the drop width W1 to W3 correspond to the drop width of the voltage drop degree ΔV is subtracted from the electric power f(M), and makes it as a provisional output electric power value, and further makes it as target output electric power P* (S220 to S290), it is controlled so that the alternate current power from an inverter may become the provisional output electric power value, and it waits for that the output voltage Vfc become stable, and after that it makes the alternate current electric power return gradually to f(M) which is the original target output power value. Therefore, it can cope with it without giving big influence on the operation when the output voltage Vfc of the fuel cell drops. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To efficiently recover heat, without making the path for a heat exchange medium complex.
SOLUTION: Since electrochemical reaction of fuel gas and oxidizing gas in a fuel cell 40 is heat generation reaction in a fuel cell power generation system 10, both anode-off gas and cathode-off gas have heat. A circulation pump 51 circulates water or hot water which is the heat exchange medium 54 in a heat exchange medium circulation path 50, in which water or hot water returns into a hot-water storage tank 52 via an anode-off gas heat exchanger 42 and a cathode-off gas heat exchanger 44 arranged in series from the hot-water storage tank 52. Consequently, the heat exchange media 54, having the same origin, recover heat from the anode-off gas and the cathode-off gas, so heat recovery is performed efficiently. Moreover, since the heat exchange medium 54 is circulated in the heat exchange medium circulation path 50 in which both the heat exchangers 42, 44 are arranged in series, the path for the heat exchange medium 54 will not become complex.

摘要： PURPOSE:To prevent the breakage of an internal combustion engine before it happens, by sensing an abnormal condition of the internal combustion engine based on output signals from a hydraulic pressure sensing means and a rotational speed sensing means and operating a stop means for stopping the internal combustion engine when the abnormal condition is sensed. CONSTITUTION:A hydraulic pressure switch 2 is disposed in the lubricating oil pipe in an engine 1, the switch 2 being opened when the hydraulic pressure in the lubricating oil pipe reaches a prescribed value. The engine 1 is provided with a rotational speed sensor 3 for delivering a frequency proportional to the rotational speed. The outputs from the hydraulic switch 2 and the rotational speed sensor 3 are applied to a control circuit 10 so that a switching circuit 5 issues an H level signal when the output from a F/V converter 4 for delivering a voltage proportional to a rotational speed is greater than a set value. When the circuit 5 issues the H level signal or the hydraulic pressure switch 2 is opened to enable an inversion buffer 8 to issue the H level signal, a logic circuit 6 determines that the engine is in an abnormal condition, then the engine 1 is stopped.
