Definitions

  • the fuel cells are connected in parallel and / or in series and have a common inlet opening and gas outlet opening. If the fuel cell stacks are not fed with pure operating gases, there is a concentration gradient of the operating gas on the anode side from the gas inlet opening to the gas outlet opening. This is the case, for example, when operating with an upstream methanol reformer for generating hydrogen.
  • the anode gas consists of approx. 55% H 2 , 22% N 2 , 22% CO and 1% O 2 at the gas inlet, whereas the H 2 concentration at the gas outlet may have decreased to up to 10%.
  • the volume parts of the other gases are then correspondingly larger.
  • the operating gas is passed through two or more fuel cell stacks connected in series to all available fuel cells, so that ideally the concentration at the gas outlet is zero.
  • the fuel cell power decreases with the operating gas concentration at the anode, ie the fuel cells before the gas outlet have a lower output power than the first fuel cells directly behind the gas inlet.
  • the fuel cell stack 1 comprises twelve fuel cells 2, which are combined in three groups 3, each with four fuel cells 2.
  • the fuel cells 2 are connected in series with one another.
  • the first fuel cell 2 has a gas inlet opening 4 and the last fuel cell 2 has a gas outlet opening 5.
  • Each group 3 is assigned a further gas inlet opening 6 with a closable gas flap 7 and a gas outlet opening 8 with gas flap 9, the first group 3 using the gas inlet opening 4 and the last group 3 using the gas outlet opening 5.
  • All gas flaps 8, 9 are preferably actuated by a common actuating signal. If an operating mode with high efficiency is desired, the gas flaps 8, 9 are controlled in such a way that they close the associated gas inlet openings 6 and gas outlet openings 8.
  • the anode gas to be converted in the fuel cell stack 1 is introduced into the gas inlet opening 4 and flows successively through all the fuel cells 2. The anode gas then exits the fuel cell stack through the gas outlet opening 5.
  • the gas flaps 8, 9 are opened and the anode gas flow is diverted accordingly, so that the groups 3 are each filled with anode gas in parallel. If the pressure drop in the fuel cell stack is large enough to supply sufficient fresh anode gas to the fuel cells 2 via the gas inlet openings 4, 6, the additional gas outlet openings 8 can be dispensed with.
  • the control signal for the gas flaps 8, 9 is preferably generated by an engine control unit and / or a battery manager, of which the required power can be easily detected. The changeover does not affect the cathode side when the cathode gas is normal ambient air. In other cases, e.g. when operating with pure oxygen, a switching of the gas streams corresponding to the anode can be provided for the cathode.
  • the electronic connection of the fuel cell stack 1 remains unaffected by all measures.
