Abstract: A solid oxide fuel cell C2 has a laminate including a solid electrolyte substrate, a cathode electrode layer 2 formed on one side of the substrate and an anode electrode layer formed on the other side of the substrate. A metallic mesh M is formed all over the solid electrolyte substrate on one or both of the cathode electrode side and the anode electrode side. The laminate includes a plurality of small fuel cell divisions C2n which are electrically connected to each other with the metallic mesh. The laminate having an electrolyte sheet of green sheet, a cathode electrode paste layer, an anode electrode paste layer and a metallic mesh laminated on each other is sintered to undergo cracking, thereby forming a plurality of small fuel cell portions.

Abstract: In a direct-flame-exposure-type fuel-cell power generating apparatus according to the present invention, a flame produced by burning a mixture gas of a fuel gas and air is supplied to an anode electrode layer, and the supply condition of the flame is adjusted in a mixture gas generating device. The temperature rising or falling speed of a solid oxide fuel cell can be adjusted by adjusting the mixture ratio and thereby changing the condition of the flame when starting or stopping the operation of the fuel cell power generation. The flame supply condition can also be adjusted by changing the spacing between the solid oxide fuel cell and a gas-fired burner.
