REMOVABLE LOAD CELL DESIGN FOR FUEL CELL STACK

This invention relates to designs and methods for desirably allowing the incorporation and/or removal of load cells (10) in a fuel cell stack (1) without significantly changing the load on the series stack of fuel cells when doing so. A relevant fuel cell stack (1) is of a simple construction comprising a compression assembly (18) located in an opening in an end-plate (3, 4) in which the assembly comprises a spring cap (11) with an inner shoulder (11a), a load cell button (12) slidable in the stack direction, and a spring assembly (13). A load cell (10) can then be incorporated along with an appropriate load cell cap (15), or removed in a like manner, without a significant change in load.
