    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.

    Abstract: A system and method for suppressing the formation of gaseous inclusions in glass sheets and the resulting glass sheets are described herein. The system includes a melting, fining, delivery, mixing or forming vessel that has a refractory metal component (e.g., platinum component) which has an inner wall that contacts molten glass and an outer wall coated with an oxygen ion transportable material (e.g., zirconia) which is coated with a conductive electrode. The system also includes a DC power source that supplies DC power across the oxygen ion transportable material which causes oxygen ions to migrate from the refractory metal component to the conductive electrode and enables one to control the partial pressure of oxygen around an exterior of the vessel which helps one to effectively prevent hydrogen permeation from the molten glass in order to suppress the formation of undesirable gaseous inclusions and surface blisters within the glass sheet. The present invention also helps one to effectively reduce the oxidation of external, non-glass contact surfaces of the refractory metal component.
