Patent Abstract

The stack has a component carrier comprising a groove-spring system that is provided for accommodation of components in the form of fuel cells, cooling cells and fuel cell-compartments. The fuel cells are formed from a membrane-electrode unit comprising two electrodes, an anode, a cathode and a membrane that is arranged between the anode and the cathode. Supply lines are arranged on a side of the component carrier and provided for separately supplying the components with operating resources. An independent claim is also included for a method for insertion of a component in the form of a fuel cell or cooling cell into a fuel cell stack.
