Abstract
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.
