A fuel cell stack assembly comprises a plurality of fuel cells in a stack, the stack defining two opposing parallel end faces. An end plate assembly is provided at each opposing end face of the stack. The end plate assemblies are coupled together to thereby maintain the fuel cells in the stack under compression. At least one, and preferably both, of the end plate assemblies comprises: a master plate 2 defining a master compression face; a slave plate 3 defining a slave compression face, the slave compression face facing the master compression face and being in compressive relationship therewith; and a plastic or viscoplastic interface disposed between the master compression face and the slave compression face. The plastic or viscoplastic interface may be bounded by a containment structure extending along a peripheral edge of the interface. The interface may be acrylic putty, silicone paste , grease or hydraulic bladder containing water or glycerine |
