摘要:
To provide a solid oxide fuel cell device capable of stably increasing the temperature of a fuel cell units and smoothly starting electrical generation. The present invention is a solid oxide fuel cell device (1), having a fuel cell module (2); a reformer (20); a fuel supply means (38); a reforming oxidant gas supply means (44); a water supply means (28); a generating oxidant gas supply means (45); and a control section (110) for causing reforming reactions to occur in the reformer at the temperature at which electricity can be generated, prior to the start of electrical generation, in the sequence: POX, in which only the partial oxidation reaction occurs, ATR, in which the partial oxidation reaction and the steam reforming reactions occur, and SR, in which only steam reforming reaction occurs; whereby the control section controls the fuel supply means so that the rate of change in the fuel supply flow rate versus time at the time of transition from the ATR to the SR is the smallest of the rates of change when the fuel supply flow rate is changed at the temperature at which electricity can be generated.

摘要:
The SOFC of the present invention has a plurality of individual solid oxide fuel cells (84) disposed within an generating chamber (10), a fuel supply unit (38) for supplying fuel to the individual solid oxide fuel cells, a temperature sensor (142) for measuring the temperature of the generating chamber (T1), and a control section (110) for changing the amount of fuel supplied in response to an amount of generation required based on control characteristics for supplying fuel, wherein the control section is furnished with a temperature band for monitoring purposes, having a minimum temperature value (Ta) and a maximum temperature value (Tb) for adaptive control, predetermined based on a minimum amount and maximum amount of rated electrical generation, and a maximum temperature value for adaptive control in response to anomalies, which is higher than the maximum temperature value (Tb) of the adaptive control temperature band, and a minimum temperature value for adaptive control in response to anomalies, which is lower than the minimum temperature value (Ta) of the adaptive control temperature band, and the control section is furnished with: an anomaly response control section for executing anomaly response control by restricting operation of the fuel cell when the generating chamber temperature (T1) is higher than the maximum temperature value for anomaly response control or lower than the minimum temperature value for anomaly response control, and with an adaptive control section for executing adaptive control by correcting the amount of fuel supplied based on a temperature signal from the temperature measurement sensor so that the generating chamber temperature (T1) is kept within the temperature band when the generating chamber temperature (T1) exceeds the minimum temperature value (Ta) or maximum temperature (Tb) for adaptive control and goes outside the temperature band.
