The present invention is concerned with an improved fuel cell stack assembly comprising a metal base plate on which is mounted at least one fuel cell stack and a metal end plate, each stack comprising at least one fuel cell stack layer that comprises at least one fuel cell and at least one electrically insulating compression gasket, wherein a skirt is attached to the base and end plates enclosing the stack and is under tension therebetween so as to maintain a compressive force through the stack, thereby obviating the need for tie-bars.

Fuel cell stack assembly

The present invention is concerned with an improved fuel cell stack assembly () comprising a metal base plate () on which is mounted at least one fuel cell stack () and a metal end plate (), each stack comprising at least one fuel cell stack layer () that comprises at least one fuel cell () and at least one electrically insulating compression gasket (), wherein a skirt () is attached to the base and end plates enclosing the stack and is under tension therebetween so as to maintain a compressive force through the stack, thereby obviating the need for tie-bars.

A fuel cell stack assembly apparatus comprising a base and a stack alignment feature extending generally perpendicular to said base for aligning ferritic fuel cell units stacked against it into a fuel cell stack assembly, wherein each fuel cell unit comprises a respective first alignment feature complimentary in shape to said stack alignment feature. Other features include a magnetic abutment extending generally perpendicular to said base for attracting the plurality of fuel cell units towards the stack alignment feature, and an alignment slider slidable generally perpendicular to said base for aligning ferritic fuel cell units stacked against the stack alignment feature. A method of using the assembly apparatus comprises stacking fuel cell units upon each other on the base with their respective first alignment features against the stack alignment feature, and attracted towards the same by virtue of the magnetic force of the at magnetic abutment.
