Abstract
A fuel cell stack comprises a thin process-gas-connection-endplate with a temperature expansion coefficient which is substantially the same as the temperature expansion coefficient of the plurality of fuel cells and interconnects forming the fuel cell stack, the length and width of the thin process-gas-connection-endplate is matching the length and width of the fuel cells and interconnects and the process-gas-connection-endplate is sealed to the stack of cells and interconnects so the process-gas-connection-endplate, cells and interconnects form one integrated unit, wherein process gas distribution tubes are fixed connected, e.g. welded or brazed to the process-gas-connection-endplate.
