COMPRESSION METHOD FOR SOLID OXIDE FUEL CELL STACKS

Abstract:

A system for a solid oxide fuel cell stack disposed between and in contact with a fixed top compression plate and a movable compression plate. At least one tension rod can be inserted through an opening on a movable locking plate, wherein the top end of the tension rod is connected to the bottom of the movable compression plate and the bottom end of the tension rod is connected to a fixed bottom compression plate. At least one nut can be used in conjunction each tension rod and disposed below the movable locking plate to secure the movable locking plate in position. Additionally, at least one spring can be disposed around the at least one tension rod and connected to the bottom of the movable compression plate and the top of the fixed bottom compression plate. Finally, at least one pneumatic cylinder can be in contact with the bottom of the movable locking plate and the fixed bottom compression plate.
