ABSTRACT:
A clamping structure for a planar solid oxide fuel cell stack comprising a flexible sheet and a rigid, thermally insulating end block, the flexible sheet being capable of bending into a primarily convex shape, the rigid, thermally insulating end block shaped as a rectangular base with a planar surface and an opposing surface that is primarily convex in shape, the flexible sheet being placed adjacent to the opposing surface of the rigid, thermally insulating end block, the flexible sheet thereby bending to obtain a shape that is primarily convex. The invention also relates to a solid oxide fuel cell stack and a process for the compression of the stack.
