  • Another problem of producing hydrogen for the fuel cell with the aid of the reforming of higher hydrocarbons or alcohols arises from the complexity of the chemical processes taking place during the reforming and the associated reaction procedure which is difficult to handle.
  • Known units for reforming the hydrocarbons or alcohols provide complex control devices for handling the complicated reaction processes and are therefore not suitable for use in mobile devices, for example automobiles.
  • the object of the invention is therefore to provide an improved method and an improved device for the reforming of higher hydrocarbons or alcohols, for example gasoline, diesel, methanol or methane, which (facilitates) hydrogen production for a fuel cell in mobile devices, in particular vehicles ,
  • microreactor network is particularly suitable as a device for generating hydrogen for non-industrial applications, since the space requirement has been considerably reduced in comparison with known (industrial) plants.
