Abstract
An electrolyte, and a process for its formation, for a solid oxide fuel cell comprising an electrolyte plate and a supporting member. The electrolyte plate includes an upper and a lower surface. The support member includes a plurality of non-intersecting support members which are positioned on at least one of the upper and the lower surfaces of the electrolyte plate.
Claims17
An electrolyte for a solid oxide fuel cell comprising:
- an electrolyte plate having an upper and a lower surface;
- and
- means for supporting the electrolyte plate, wherein the supporting means includes a plurality of independent non-intersecting support members constructed from substantially the same material as the electrolyte plate positioned on at least one of the upper and lower surface of the electrolyte plate.
A method of manufacturing an electrolyte for a solid oxide fuel cell comprising the steps of:
- providing an electrolyte plate having an upper surface and a lower surface;
- providing a second plate constructed from substantially the same material as the electrolyte plate;
- forming at least one opening through the second plate;
- positioning the second plate on one of the upper and the lower surface of the electrolyte plate in a desired orientation;
- associating the electrolyte plate with the second plate;
- and
- trimming the associated electrolyte plate and second plate so as to render a plurality of independent non-intersecting support members on the electrolyte plate.
