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 stack () of intermediate temperature, metal-supported, solid oxide fuel cell units (), each unit comprising a metal support substrate (), a spacer () and an interconnect () that each have compression bolt holes (), fuel inlet port (), fuel outlet port () and air outlet () therein, wherein bolt voids () are formed by aligning the bolt holes and a further void () by aligning the air outlets, and the voids are vented, for example, to the environment or further void to prevent the build-up of fuel, moisture or ions.
