The electrolyte comprises a third ceramic layer.    USE - The solid oxide fuel cell is useful in a cell stack (claimed).    ADVANTAGE - The solid oxide fuel cell can be easily and economically manufactured with desired electrical and mechanical properties, has enhanced redox stability, increased operating life, reduced ionic resistance and improved performance, minimizes the orange discoloration associated with degradation of scandia-stabilized zirconia electrolyte, minimizes hydrogen diffusion within the electrolyte, and avoids the cracking due to thermal cycling.    DETAILED DESCRIPTION - The solid oxide fuel cell (1) useful in a stack, comprises an anode (3), a cathode (7), a solid oxide or ceramic electrolyte (5) located between the anode and the cathode, a non continuous ceramic support layer located on the anode or on the cathode, an electrode located on an opposite side of the electrolyte, and a seal. The anode comprises a porous first ceramic layer infiltrated with an anode catalyst material. The cathode comprises a porous second ceramic layer infiltrated with a cathode catalyst material. The electrolyte comprises a third ceramic layer having a lower porosity than the first and the second ceramic layers. A material of the third ceramic layer is different from a material of the first and the second ceramic layers. A fourth ceramic layer is located between the first ceramic layer and the third ceramic layer. A fifth ceramic layer is located between the second ceramic layer and the third ceramic layer. The fourth and the fifth ceramic layers comprise doped ceria layers. A peripheral portion of the porous first ceramic layer is filled with a seal material. A portion of the third ceramic layer is folded over a peripheral portion of first ceramic layer. The anode and cathode layer are 20-100 microns thick. The planar fuel cells are separated by a gas separator/interconnect plates. The electrolyte is less than 20-50 mu m thick. The porous first ceramic layer is 200-500 mu m thick. The electrode has a thickness of 10-30 mu m. The electrolyte has a fuel inlet or outlet riser opening, and comprises an active region and an inactive region. The anode contacts the electrolyte on its first side of the electrolyte, and the cathode contacts the electrolyte on its second side opposite to the first side. A ceramic reinforcing region is located partially around a circumference of the riser opening, and on the inactive region of the electrolyte. A combined thickness of the electrolyte and the ceramic reinforcing region is 25-150 mu m thicker than a thickness of the active region and the inactive region that does not contain the ceramic reinforcing region. The reinforcing region comprises a semicircle, horseshoe, crescent, or U shape. The seal is located on the second side entirely around the circumference of the riser opening. The reinforcing region comprises a screen printed ceramic, and a laminate of electrolyte material comprising yttria or scandia. The screen printed ceramic contains reinforcing fibers or particles. INDEPENDENT CLAIMS are included for:    (1) a method of making a solid oxide fuel cell; and    (2) a method of making a hole-reinforced electrolyte.
