Summary:A stack for a fuel cell system which can include a simplified fastening structure and a fuel cell system having the stack are shown. The stack includes at least one electricity generator, a housing, and a cover. The electricity generator includes a MEA and separators located on both surfaces of the MEA. The housing has an internal space in which the electricity generator is positioned, and a cover coupled to the housing to fix the electricity generator in place. A number of various mechanisms are shown for holding the housing and the cover together and for fixing the stacks in place. A number of reinforcing elements and structural shapes are also shown that yield a stronger housing and cover assembly that resists buckling and other forms of stress.
