Abstract: A bus bar for an electrolyte sheet is provided that includes a bus strip (37) of electrically conductive material in contact with a side edge of the cell or cells in the electrolyte sheet, wherein the amount of material in shoulder portions (39, 45) of the bus strip (37) decreases as the strip approaches end portions of the cell edge to reduce stress. Preferably, such material reduction is accomplished by tapering the shoulder portions (39, 45) of the bus strip (37). The tapered shape of the shoulders reduces the amount of electrical conductor needed to form the bus bar. The stress reducing bus bar also includes a lead (41a, 41b) which is orthogonally oriented with respect to the longitudinal axis of the side edge of the cell. The tapered shape of the shoulder portions of the bus strip, in combination with the orthogonally oriented lead, reduces stresses that would otherwise occur between the bus bar and the electrolyte sheet as a result of differences in the thermal coefficient of expansion. The specific shape of the taper in the shoulder portions is selected such that I 2 R losses are substantially minimized along the longitudinal axis of the bus strip.

Abstract: A stress reducing mounting for an electrolyte sheet assembly in a solid electrolyte fuel cell includes a support frame or manifold that supports a peripheral portion of the sheet assembly, a seal that affixes an edge 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 and mounting reduces cracking in the electrolyte sheet at the peripheral portions due to tensile forces. The stress reducer is either a convex curved surface on the frame or manifold that makes area contact with the peripheral portion when it bends or a stiffening structure on the sheet peripheral portion that renders the ceramic sheet material forming the peripheral portion more resistant to bending.
