This invention relates to a fuel cell system with a polyelectrolyte membrane fuel cell and a method by which the pressure inside the fuel cell can be regulated by means of the quantity of fuel introduced. This regulation is accomplished by means of pressure sensors which are controlled by means of an electronic control unit.

Fuel cell system and method for regulating pressure in fuel cell systems

A planar fuel cell system comprising at least two fuel cells which are electrically connected in series in a plane via horizontally overlapping connecting lugs and comprise an anode current collector on the anode side and comprise a cathode current collector on the cathode side is provided. The current collectors are electrically connected to the connecting lugs and a polymer electrolyte membrane, wherein the current path is led around the polymer electrolyte membrane. The fuel cell system is designed with a printed circuit board technique and as a composite of a first, anode-side printed circuit board and a second, cathode-side printed circuit board, and the current collectors and connecting lugs are designed as strip conductors of these printed circuit boards. Methods of manufacturing the fuel cell system are also provided.
