The membrane unit (12) has a cathode (14), an anode (16) and a proton-conductive membrane unit (18) arranged between the anode and the cathode. The membrane unit has a catalytic intermediate layer (24) at which water is produced by a catalytic reaction of an oxidator and a fuel. The catalytic intermediate layer is electrically connected with the cathode and the anode, and is arranged between membrane layers. |
