Definitions

  • the present invention relates to a media distribution device for distributing gaseous media to an arrangement of several fuel cell stacks, in particular a high-temperature fuel cell system such as a SOFC system (solid oxide fuel cell system) with high operating temperatures.
  • a high-temperature fuel cell system such as a SOFC system (solid oxide fuel cell system) with high operating temperatures.
  • fuel cell systems must be supplied with media in order to operate.
  • gaseous operating media in the form of anode feed gas, anode exhaust gas, cathode feed gas and cathode exhaust gas.
  • fuel cells are operated with air and fuel, so that air must be supplied to the respective fuel cell and the corresponding exhaust gas generated from the air must be removed. To the same extent, fuel must be supplied to the fuel cell and the resulting exhaust gas must be removed.
  • a fuel cell system has a large number of individual fuel cells in the form of several fuel cell stacks, these are often arranged modularly in rows next to one another and functionally similar media flows are combined into a central media flow at various branching points to simplify the design, but also to ensure a uniform supply when the fuel cell stacks are operated in parallel.
  • waste heat from anode exhaust gas is mainly transferred to fresh fuel and waste heat from cathode exhaust gas to fresh air using heat exchangers.
  • the term fuel supply includes the supply of both a pure fuel gas and a fuel gas with any proportion of a recirculation gas that introduces a lower fuel concentration due to prior reactions of the fuel at an anode.
  • the media distribution device is used to distribute gaseous media to an arrangement of several fuel cell stacks.
  • the media distribution device comprises at least, among other things, an air supply section for supplying the fuel cell stacks with air and a fuel supply section for supplying the fuel cell stacks with fuel.
  • the air supply section has a common air supply chamber for distributing supplied air from an upstream, supplying flow path to several downstream, discharging flow paths.
  • the fuel supply section has a common fuel supply chamber for distributing supplied fuel from an upstream, supplying flow path to several downstream, discharging flow paths.
  • the air and/or the fuel is supplied centrally.
  • a central air duct in particular benefits from this heat exchange, although an axial air supply could also benefit from it. It can therefore also be advantageous for the air to be supplied axially.
  • at least a portion of the fuel supply chamber is accommodated within the air supply chamber, wherein the air supply chamber, at least at the accommodated portion of the fuel supply chamber, surrounds a boundary of the fuel supply chamber.
  • surrounding is to be understood in particular as contacting or contacting for the purpose of conscious heat exchange.
  • the invention thus provides for the first time a system technology for fuel cells, in particular for high-temperature fuel cell stacks, in which a volume of the gas duct for the air and a volume of the gas duct for the fuel are arranged in a spatial overlap with one another on a distributor, i.e. immediately in front of connections for supplying the gases to the fuel cells, i.e. in particular a circumference of the volume of one gas duct surrounds or encloses a circumference of the volume of the other gas duct at least in sections.
  • a major advantage of the invention is that the arrangement and design of the fuel supply chamber within the air supply chamber according to the invention provides intensive heat transfer from the gas flow of the fuel, which usually has a higher temperature due to a recirculation flow, to the gas flow of the air.
  • the temperature difference between the supplied fuel and the supplied air i.e. a temperature at a membrane of the fuel cell
  • this can vary between different operating points of the fuel cell system, whereby, for example, a temperature gradient can also be in the opposite direction. This is the case, for example, with preheating, where the air is significantly warmer than an anode exhaust gas.
  • the gas flow of the fuel on a line section upstream of the fuel cells loses no or only a reduced amount of heat to the environment, since this is at least partially surrounded by the gas flow of the air.
  • the media supply system loses less thermal energy to the environment and the efficiency of energy generation is again improved.

  • the fuel supply chamber and the air supply chamber can be substantially cylindrical and with different circumferential radii, and the fuel supply chamber can be accommodated substantially coaxially with respect to the circumferential radii within the air supply chamber.

  • the fuel supply chamber comprises two external sections, which both enter the internal section of the fuel supply chamber together, particularly at the rear end, in order to maximize the contact area between the air and fuel-carrying parts.
  • At least one peripheral section of a boundary of the outer section of the fuel supply chamber can be formed by the boundary of the air supply chamber.
  • a boundary for the heat transfer is reduced to the thickness of a chamber wall of the air supply chamber.
  • a flow direction of the outer portion of the fuel supply chamber can run substantially parallel to an axial direction of the cylindrical air supply chamber.
  • the entire axial length of the air supply chamber is used.
  • a flow direction of the outer section of the fuel supply chamber can run essentially spirally around the cylindrical boundary of the air supply chamber. In this way, a flow path is lengthened and an area for heat transfer is increased.
  • media-carrying sections at least the air supply chamber and the fuel supply chamber, as well as
  • the air supply channels and the fuel supply channels are made of welded tubular bodies, preferably made of high-temperature-resistant steel.
