Abstract
A robotic fuel cell assembly system includes an end-effector, robotic workcell, and fuel cell components that have integrated design features that allow accurate component alignment during the assembly process of a fuel cell stack within a desired tolerance, while avoiding component overlap, which is a major cause of overboard gas leaks during the fuel cell operation. Accurate component alignment is achieved by electrically non-conductive alignment pins that are mounted on a fuel cell base plate, which are configured to be received by guide holes formed on the fuel cell components, and alignment holes provided by an alignment arm attached to the end-effector. The end-effector also includes a passive compliance system that includes two perpendicularly mounted miniature linear blocks and rails, which serve to compensate for the limitations in the ability of the robotic arm to move the end-effector accurately in a repeated manner.
