ABSTRACT:
The invention relates to a contact device which is arranged in a terminal compartment of a fuel cell stack and is used to electrically contact the fuel cell stack. According to the invention, the surface of said contact device is at least partially provided with a hydrophobic surface layer, facilitating the removal of water, e.g., condensation water, from the terminal compartment and thus from the fuel cell stack.
