    摘要： A stress reducing mounting for an electrolyte sheet assembly in a solid electrolyte fuel cell is provided that includes a support frame or manifold having an inner edge portion that supports a peripheral portion of the sheet assembly, a seal that affixes an edge of the peripheral portion to the frame or manifold, and a stress reducer disposed around the peripheral portion of the electrolyte sheet and the frame or manifold that reduces tensile stress in the peripheral portion of the electrolyte sheet when the peripheral portion is bent by pressure differentials or thermal differential expansion. The stress reducer is at least one of a convex curved surface on the inner edge portion of the frame or manifold that makes area contact with the peripheral portion when it bends in response to a pressure differential or thermal differential expansion, and a stiffening structure on the sheet peripheral portion that renders the ceramic sheet material forming the peripheral portion more resistant to bending. The stress reducing mounting reduces cracking in the electrolyte sheet at the peripheral portions due to tensile forces.

    摘要： A method for making a thin, free-standing ceramic sheet may include drawing a carrier film proximate a casting head and across a casting bed of a tape caster at a rate from about 2 cm/min to about 500 cm/min. Depositing a thin film of ceramic slip less than about 150 μm on the carrier film with the casting head. The ceramic slip may comprises a ceramic powder with an ultimate crystallite size of less than about 10 μm dispersed in a fluid vehicle such that the ceramic slip has a ceramic solids fraction of greater than about 20% by volume. The deposited ceramic slip may be dried on the carrier film thereby forming a green ceramic sheet on the carrier film. After the green ceramic sheet is dried, the green ceramic sheet may be sintered.
