NOVELTY - A fuel cell has a stack of membrane electrode units separated by bipolar plates and has distributor and collector channels for hydrogen and oxygen running through the stack and end plates. The units and plates are all surrounded by plastic frames which are glued or welded together to form gas tight joints between the channels in the frames.    USE - The fuel cells are used for the production of electrical energy for use e.g. in road vehicles, space vehicles and power stations (for peak load) or as oxygen sensors.    ADVANTAGE - A simple, functional, lightweight and relatively low-cost type of fuel cell is produced more rapidly and cheaply on a continuous basis from individual elements without special seals and clamps.    DETAILED DESCRIPTION - A fuel cell has a stack of membrane electrode units (1) with their flat sides one behind the other and separated from one another by bipolar plates (10). Simple pole flanges are provided as end plates before the first and behind the last membrane unit while distributor (3, 6) and collector (4, 7) channels run through the stack for the supply and discharge of hydrogen and oxygen to and from the cathode and anode spaces between (1) and (10) and between (10) and the end plates, via side branches to these spaces. In this system, the electrode units (1), the bipolar plates (10) and the end plates are each surrounded by a separate plastic frame (2, 12), the channels (3, 6; 4, 7) and their side branches are located in these frames and the frames are glued or welded together to form gas tight joints between the channels in the individual frames.    An INDEPENDENT CLAIM is also included for a vehicle with a fuel cell as described above.    DESCRIPTION OF DRAWING(S) - Plan view of a membrane electrode unit is shown.
