A fuel cell unit includes a cassette holder for a ceramic fuel cell element sandwiched between interconnects of a novel design. The cassette holder isolates the cell from the surrounding interconnect by means of a pliant seal within a rigid frame, thereby reducing the possibility of breakage of the brittle cells. The cassettes are assembled between an upper and lower interconnect to isolate the upper face of the cell from the lower face of the cell. A fuel cell unit includes an upper and lower interconnect containing a cassette. A fuel cell stack is formed from a plurality of fuel cell units.

Flat plate fuel cell stack

A compression device for use with a solid oxide fuel cell stack is formed from a hermetically sealed cylindrical shell filled with an expansion fluid such as air. The shell has a corrugated sidewall which permits axial deformation as the compression device is heated. The shell applies a compressive frame to the stack when installed in the fuel cell stack.
