  • the object of the present invention is to provide a fuel cell system and a method in which operation can be improved in particular at low temperatures, and therefore also the starting behavior can be improved.
  • a first aspect of the invention relates to a fuel cell system having at least one fuel cell whose anode side is connected to a fuel branch via which fuel can be passed to the anode side. Furthermore, the fuel cell system comprises a recirculation branch for off-gas feedback, which is tapped off from the fuel branch at a tapping point downstream from the fuel cell and opens into the fuel branch at an opening upstream of the fuel cell.
  • the fuel cell system furthermore has a heat transfer apparatus, which is thermally coupled to the fuel branch and is designed to heat the fuel flowing in the fuel branch.

  • a metering unit is arranged in the fuel branch upstream of the opening, or directly adjacent to the opening. This allows the fuel flowing in from a fuel container to be supplied in a metered form to the anode side of the fuel cell. If the fuel cell system has been shut down and has been cooled down to low temperatures, in particular to temperatures below O 0 C 1 water can condense out adjacent to the metering unit or, shutdown processes can result in water being introduced into the metering point, and freezing there. This reduces the fuel flow after the fuel cell system has been restarted.
  • water which has collected adjacent to the inlet point of the unused metering component can freeze as a consequence of the cold fuel being supplied, leading to malfunctioning of the metering unit.
  • the fuel cell system is heated within a short time after starting.
  • the temperature falls adjacent to the mixing point and therefore also adjacent to the opening of the recirculation branch into the fuel branch, and water condenses.
  • This production of liquid water can be reduced or even entirely prevented by preheating the fuel as in the fuel cell system according to the invention. This makes it possible to prevent the metering unit from freezing, in particular adjacent to the mixing point in the area of the opening of the recirculation branch.
  • the heat transfer apparatus with its specific arrangement in the fuel cell system can particularly preferably be used to heat the fuel to temperatures of > O 0 C, thus in particular making it possible to thaw out frozen metering units and/or mixing points.

  • the heat transfer apparatus is arranged in the recirculation branch upstream of the separator in the flow direction of the gas, then this makes it possible to change the dew point in the metering unit and/or the mixing point adjacent to the opening of the recirculation branch in the fuel branch, upstream of the separator.
  • the heat transfer apparatus may also have an electrical heating unit. It is also possible to provide for the heat transfer apparatus to have at least one heat exchanger and at least one electrical heating unit.
  • the heat transfer apparatus can be coupled to the fuel cell and/or to a cooling circuit and/or to an electrical heating unit. Heat can also be introduced by means of air that has been heated by a fan or a compressor, and/or by catalytic combustion of hydrogen.

Furthermore, it is possible to reduce water condensation adjacent to the inlet point of the fresh fuel, in particular hydrogen. Furthermore, constant operating conditions can be achieved and the design of the components can be improved, in particular the design of a pressure control valve for pressure regulation of the fuel flowing from the fuel container into the fuel cell. At the moment, this pressure control valve must be designed for fuel temperatures from - 25 0 C to +85°C, while the design of the system according to the invention means that this is no longer necessary, and this value range can be reduced.
