Title: Fuel cell power generation system
Inventor: TAJIMA OSAMU
IPC: H01M8/04
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To prevent decrease of the generating efficiency due to temperature lowering of water supplied to a reformer even when sufficient heat cannot be supplied by the reformer in a period of immediately after start of power generation. SOLUTION: When a current time becomes a start time of the midnight-power time band, a system controlling device 62 halts supply of natural gas and water to a reformer 10 to shut down power generation by a fuel cell 12. With the shutdown of power generation, the system controlling device 62 controls supply of a driving current to a heater 44 to heat water in a water storage tank 42 up to a target temperature by the heater 44. When a current time becomes an end time of the midnight-power time band, the system controlling device 62 restarts the supply of the natural gas and water to the reformer 10 to restart power generation by the fuel cell 12. Consequently, soon after the power generation is restarted, hot water in the water storage tank 42 heated to a target temperature (for example, 90 to 100 deg.C), is supplied to the reformer 10.

Filed: 1994-05-11
Abstract: PURPOSE:To prevent erroneous judgment due to the insulation failure of an electrode and the failure of a circuit and to achieve fail-safe for preventing an accident by detecting water level according to the difference in characteristics of pulse signals. CONSTITUTION:An AC voltage is applied to a water level detection electrode 2 and two thresholds V1 and V2 are set between the value of the detection signal of the arrival of water level and that of the detection signal of the non-arrival of water level. A 'True' logic judgment is performed when the detection signal is within the thresholds V1 and V2, the logic judgment output signal is smoothed, and then the smoothing output signal is compared with a specific threshold V3, and then a pulse signal is generated when the threshold V3 is exceeded. The pulse signal becomes a pulsive signal when the water level reaches a water level detection edge 2a of the detection electrode 2 and becomes a non-pulsive signal with a certain value when the waver level does not reach the water level detection edge 2a or when the detection circuit and the water level detection electrode 2 are subjected to insulation failure.
