Abstract

The invention relates to a fuel cell stack comprising a base plate supporting fuel cells and a cap of an electrically insulating material, particularly of ceramics, for electrically insulating the fuel cells stacked on top of each other partially enveloping the fuel cells stacked on top of each other. According to the invention it is contemplated that a metal cap provided for guiding cathode gas envelops the cap including the fuel cells together with the base plate and that the metal cap is attached to the base plate in a sealed manner. The invention further relates to a method for producing a fuel cell stack.
