Patent ID: 7351492

Claim:
A process for producing an electrode support substrate in sheet form for a solid oxide type fuel cell comprising: providing a slurry comprising a conductive component powder, a skeleton component powder, a pore-forming agent powder and a binder, wherein the slurry is defoamed under reduced pressure after milling to adjust the viscosity thereof to 40 to 100 poise (25° C.), and kept at room temperature while rotating stirring fans therein at a rotating speed of 5 to 30 rpm for 20 to 50 hours, and wherein a particle size distribution of the slurry has a peak in each of ranges of 0.2 to 2 μm and 3 to 50 μm, and a content ratio by mass of fine particles in the range of 0.2 to 2 μm to coarse particles in the range of 3 to 50 μm is in a range of 20/80 to 90/10; fashioning the slurry into a sheet by a doctor blade method to obtain a green sheet, wherein the green sheet is a precursor of the electrode support substrate; cutting the green sheet into a given shape; and then firing the green sheet having the given shape to produce the electrode support substrate.
