Definitions

  • Recirculation blowers are also referred to as anode recirculation blowers or ARB for short.
  • Recirculation fans are components of an anode subsystem of the fuel cell, which usually has a water separator upstream of the recirculation fan to separate the process water of the fuel cell.
  • recirculation blowers can also have an integrated water separator.
  • the combination of two water separators is intended to further increase the proportion of separated process water in order to pump as little water as possible to the fuel inlet through the recirculation blower.
  • process water Even if a large proportion of the process water can be separated in this way, a small amount of process water can still remain within the anode subsystem, for example in pipes or within the recirculation fan.
  • the remaining process water can freeze when the vehicle is parked and temperatures are below 0 °C and may block moving components or small channels in the fuel cell. Especially with the recirculation fan there is a risk that the remaining process water will form ice bridges.
  • Ice bridges are ice connections between two components caused by icing. Ice bridges are particularly problematic in components that have to move relative to each other during operation. Ice bridges can therefore mean that the recirculation fan cannot be controlled or rotated when starting.
  • a common and well-known position where ice bridges often form is a gap between a magnet pot of the recirculation fan and a gap pot of the recirculation fan. The formation of ice bridges at this point prevents a recirculation fan impeller from turning loose. If the torque of the recirculation fan is not sufficient to break the ice bridges, the recirculation fan cannot operate in this state.
  • the heat can be provided, for example, by additional heating cartridges, which can be installed in an impeller housing of the recirculation fan.
  • the heat can be provided by deliberately generating eddy current losses in the recirculation fan. It is also known to control the recirculation fan in a targeted manner to break off the ice bridges, for example by oscillating. All such devices and methods aim to remove the ice that is already present as part of a start-up process for the fuel cell.
  • a method for operating a fuel cell with a recirculation fan comprises:
  • the method is carried out before an ambient temperature of the motor vehicle reaches or falls below freezing point.
  • the heating device provides heat for evaporating the water.
  • providing heat to the recirculation fan can include, for example, providing heat to an outside of the recirculation fan and/or inside the recirculation fan.
  • the heat is preferably provided in such a way that the heat is supplied to process water collection points where process water collects in order to evaporate this process water in a targeted manner.
  • the heat is preferably provided in such a way that the recirculation fan or at least parts of the recirculation fan, in particular which are in contact with process water, are heated to a temperature of at least 100 °C.
  • the water is evaporated at the recirculation fan.
  • the water is therefore supplied with heat in such a way that it evaporates.
  • the predefined evaporation criterion is met, the heat supply for evaporating the water is stopped.
  • the evaporation criterion determines when the heat supply should stop.
  • the evaporation criterion can, for example, specify which amount of water should be safely evaporated or how high the proportion of evaporated water should be in relation to the total remaining amount of water before evaporation.
  • the evaporation criterion can, for example, specify that at least 95% of the remaining water must have evaporated.
  • Compliance with the evaporation criterion can be checked, for example, using characteristic maps, empirical values or the like. After the heat supply has ceased, there is only so much water left in or on the recirculation fan that there is no longer a risk of channels or rotating parts on the recirculation fan becoming blocked by frozen water, or the risk is only such that any ice that has formed can be easily removed by operating the recirculation fan and without any delay in the operation of the recirculation fan.
  • a method according to the invention for operating a fuel cell with a recirculation fan has the advantage over conventional methods that the extent of icing on the recirculation fan can be significantly reduced using simple means and in a cost-effective manner. If the method according to the invention is carried out accordingly, the formation of ice in the area of the recirculation fan can be completely prevented. This means that the fuel cell can be put back into operation without delay when the motor vehicle is started. Complex de-icing processes are no longer necessary.
  • the evaporation of the water has the further advantage that the fuel gas, such as hydrogen, conveyed to the fuel inlet via the recirculation fan contains no or only a very small amount of water.
  • a method can be provided for the heat to be provided while the fuel cell is inactive.
  • the method is preferably carried out immediately after the fuel cell is switched off.
  • switching off the fuel cell means putting the fuel cell into an inactive state.
  • no hydrogen is supplied to the fuel cell for combustion, so that no electrical current is generated and no process water is produced.
  • no oxygen is supplied to the fuel cell in the inactive state.
  • an electric motor of the recirculation fan is operated as a heating device for providing the heat for evaporating the water by specifically controlling the electric motor.
  • the electric motor is preferably controlled in such a way that the iron losses are particularly high. This can be done, for example, via voltage vectors of equal magnitude with a phase shift of 180°, with the voltages being provided at a predetermined frequency, so that a constant change in the flow direction of the magnetic field of the electric motor is thereby caused.
  • the control is preferably carried out in such a way that no rotating field is generated for rotating the rotor.
  • the targeted control of the electric motor causes the stator and/or the rotor of the electric motor to heat up, preferably to a temperature of over 100°C, so that the remaining process water is thereby evaporated.
  • This has the advantage that the heat for evaporating the water is provided using simple means and in a cost-effective manner. Additional heating devices are not required, so that the costs and weight of the fuel cell can be reduced.
  • the heating device is preferably arranged directly on the recirculation fan in order to heat the recirculation fan in a targeted manner.
  • the heating device can have, for example, a heat exchanger and/or a resistance heating element and/or a burner device or the like.
  • the heating device is preferably designed in such a way that the heating device can be controlled independently of the control of the recirculation fan. This means that the rotor of the recirculation fan can continue to operate when the heating device is activated, for example.
  • the heating device that can be controlled separately from the recirculation fan and the recirculation fan are preferably used as the heating device to provide the heat for evaporating the water, so that the dimensioning of the separately controllable heating device can be particularly cost-effective, space-saving and lightweight to provide the required heating energy.
  • This has the advantage that it can be achieved with simple means and in a A particularly efficient evaporation of water is achieved in a cost-effective manner.
  • a method can be provided in which the recirculation fan is operated in fan mode to remove the evaporated water. As the water evaporates, at least part of the evaporated water is removed from the fuel cell. In order to prevent the water from condensing again on the recirculation fan after the heat supply has ended, from depositing on the recirculation fan and from forming ice bridges in the event of frost, the recirculation fan is operated to transport the water out of the recirculation fan. This has the advantage that a particularly large proportion of the water can be removed from the fuel cell using simple means and in a cost-effective manner, thus significantly reducing the risk of ice bridges forming.
  • a specific time period for providing the heat to evaporate the water is used as the evaporation criterion. If the heating output of the heating device is known, it is easy to determine from experience, simulations, algorithms, characteristic maps or the like which amount of water has evaporated after a defined period of time with a defined heating output. By estimating the amount of water present before the heat is provided to evaporate the water, the time period after which the amount of water has evaporated can be determined. A safety factor can be used here so that a higher amount of water is assumed when determining the time period, for example. This ensures that the recirculation fan is also dry after the heat has been provided for the defined period of time.

  • Parallel controls of the recirculation fan and/or the separately designed heating device by the fan control device and the central control device can also be provided within the scope of the method. This has the advantage that reliable control of the heating device to provide the heat is ensured using simple means and in a cost-effective manner.
  • an outside temperature is determined in the area of the fuel cell, whereby the provision of heat for Evaporation of the water occurs specifically when the outside temperature falls below a temperature threshold.
  • the temperature threshold can be between 3 °C and 5 °C, for example. If the outside temperature is higher than the temperature threshold, no heat is provided to evaporate the water.
