    摘要： Provided is a fuel cell as a fired body including a porous plate-like support substrate having a gas flow path formed therein, and a power generation element part provided on a principal surface of the support substrate, the power generation element part including at least a fuel electrode, a solid electrolyte, and an air electrode laminated in this order. The generation of cracks in the support substrate has a strong correlation with a “surface roughness of a wall surface of a gas flow” of the fuel cell in a state of a reductant. When the surface roughness of the wall surface of the gas flow path is 0.16 to 5.2 in terms of an arithmetic average roughness Ra in a state in which the fuel cell is a reductant that has been subjected to heat treatment in a reducing atmosphere, the generation of the cracks can be suppressed.

    摘要： A fuel cell stack includes seven current collecting members and six fuel cells that are alternate stacked with reference to the stacking direction. Each of the six fuel cells includes an anode, a cathode and a solid electrolyte layer that is disposed between the anode and the cathode and contains a zirconia-based material as a main component. The six fuel cells include a first fuel cell disposed in the center with reference to the stacking direction, and a second fuel cell disposed in one end with reference to the stacking direction. An intensity ratio of tetragonal crystal zirconia to cubic crystal zirconia in a Raman spectrum of the solid electrolyte layer of the first fuel cell is greater than an intensity ratio of tetragonal crystal zirconia to cubic crystal zirconia in a Raman spectrum of the solid electrolyte layer of the second fuel cell.

    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.
