Claims
- 1. A method for producing a solid oxide fuel cell, the method comprising the steps of:
- spreading out a grainy electrolyte on a first surface and a second surface of a green sheet of solid electrolyte;
- putting a green sheet of fuel electrode on the first surface of the solid electrolyte with the grainy electrolyte in-between and putting a green sheet of air electrode on the second surface of the solid electrolyte with the grainy electrolyte in-between to form a laminate of green sheets of solid electrolyte, of fuel electrode and of air electrode;
- pressing the laminate of green sheets so that the green sheets are fixed together; and
- sintering the laminate of green sheets to obtain a solid electrolyte with a fuel electrode and an air electrode thereon.
- 2. A method for producing a solid oxide fuel cell as claimed in claim 1, wherein:
- particles of the grainy electrolyte have diameters more than 10 .mu.m in average and less than thicknesses of the fuel electrode and the air electrode.
- 3. A method for producing a solid oxide fuel cell as claimed in claim 2, wherein:
- the particles of the grainy electrolyte have an average diameter of about 30 .mu.m.
- 4. A method of producing a solid oxide fuel cell as claimed in claim 3, wherein:
- the grainy electrolyte is yttrium stabilized zirconia powder.
