Definitions

  • Fuel cell system for a vehicle in particular a motor vehicle
  • the invention relates to a fuel cell system for a vehicle, in particular a motor vehicle, with at least one fuel cell module and / or a fuel cell stack.
  • the latter fuel cell stack is also referred to in technical terminology as a fuel cell stack or in short as a “stack ⁇ ”.
  • Fuel line systems are known for stationary and / or mobile applications.
  • EP 0 677 412 B1 describes such a system specifically for use in a motor vehicle (motor vehicle) in which the fuel cell module itself is in a separate support structure in or below of the vehicle floor is arranged, with all units of the fuel cell system, as well as the ancillary units, being protected in the support structure, but nevertheless being accessible from the outside.
  • the arrangement of the fuel cell system in the support construction serves primarily to mechanically protect the fuel cell modules or the individual stacks in the event of sudden external influences, in particular accidents. That being said, during everyday operation of motor vehicles equipped with fuel cell systems, the fuel cell stacks in the vehicle are stressed by a wide variety of influences from the vehicle. By the automotive operation itself, but also already during idling of the electric motor, the fuel cell stack considerable mechanical 'is exposed to alternating loads.
  • the object of the invention is therefore to propose suitable measures to reduce the mechanical loads on the fuel cell.
  • the invention proposes to attach the fuel cell stack and / or the fuel cell module to the vehicle in a mechanically decoupled manner.
  • the entire fuel cell system can be positioned at a suitable location under the vehicle floor or at the location of the vehicle chassis.
  • the fuel cell module is designed as a ' surface stack, which is mechanically decoupled by means of damping elements on an under or intermediate floor of the vehicle.
  • the surface stack can also be suspended from the vehicle floor, which likewise results in mechanical decoupling from the vehicle.
  • the arrangement of the fuel cell modules or fuel cell stacks is advantageously provided at a suitable point on the vehicle body in such a way that there are no notable aerodynamic changes.
  • undesirable changes in the vehicle's cd value can be avoided, while air can still reach the surface stack when the vehicle is moving.
  • the invention can be implemented in particular with those fuel cell modules which have a flat design, i.e. are constructed as a so-called area stack with HT-PEM fuel cells.
  • the complete fuel cell system can be designed so that only the surface stack with the HT-PEM fuel cells is decoupled at a suitable location on the vehicle body, so that despite the surface stack and airflow feeds, the specific drag coefficient of the motor vehicle achieved by the vehicle design is essentially maintained becomes.
  • FIG. 1 shows a on the underbody of a vehicle with a mechanically decoupled fuel cell module positioned thereon
  • FIG. 2 shows the top view of a fuel cell module from below
  • FIG. 3 shows an alternative arrangement to FIG. 1.
  • 1 denotes a motor vehicle (KFZ) which, for example, has an electric motor 3 as a drive and a fuel cell system 10 for supplying the drive.
  • KFZ motor vehicle
  • a further base plate 2 can also be present as a base plate 2 ′ as the base plate, so that the fuel cell attachments ⁇ ⁇ ro IV) P * h- 1 * (io ⁇ o C ⁇ o C ⁇ s: o ⁇ ⁇ -5 o 3 p> l- 1 2!

  • FIG. 2 An alternative to FIG. 1 with a suspension of the surface stack on the carriage floor 2 results from FIG.
  • damping elements 11 to 14 conventional means such as springs in particular, but also rubber buffers or the like are common. , in question.
  • the damping elements 11 to 14 are matched in detail to the resonance properties of the vehicle body of the motor vehicle 1 on the one hand and the fuel cell system 10 on the other.
  • the running properties of motor vehicle 1, in particular also the idling properties of engine 3, are also taken into account.
  • Effective mechanical decoupling of the structural units can thus be achieved with simple means, with which, in particular, a negative influence of vibrations on the sensitive parts of the fuel stack, in particular the polymer membrane as the core of the fuel cell or - including the electrodes - the so-called membrane electrode Unit-MEA) can be excluded.
  • PEM fuel cells are fuel cells that work with polymer electrolyte membranes based on the principle of proton exchange in the membrane (Proton Exchange Membrane).
  • the working temperatures of the common PEM fuel cells are, for example, 60 ° C, in any case below 100 ° C, because at normal pressure the water necessary for the water balance of the fuel cell evaporates there.
  • so-called HT (high temperature) PEM fuel cells have also been proposed, which promise improved application properties.
  • HT-PEM fuel cells in particular work at temperatures between 60 ° C and 300 ° C, especially at normal pressure between 120 ° C and 200 ° C.
