1. A fuel supply device for supplying a fuel to an internal combustion engine comprising:
a fuel store for storing a primary fuel;
and at least two parallel fuel supply paths that are connected to the fuel store, and to the internal combustion engine, wherein
the primary fuel can be suppled from the fuel store to the internal combustion engine by means of a first fuel supply path for the purpose of combustion; and
a second fuel supply path has at least one reforming device by means of which the primary fuel supplied from the fuel store is reformable into a secondary fuel and at least a portion of the secondary fuel can be supplied to the internal combustion engine for the purpose of combustion,
wherein a secondary fuel store for storing the reformed secondary fuel is provided and/or at least one compressor/pump is included downstream after the reforming device to be able to supply the reformed secondary fuel at an elevated pressure to at least one of the internal combustion engine, the secondary fuel store, and an exhaust aftertreatment device, and
wherein the second fuel path has at least one branching downstream after the reforming device to be able to provide the reformed secondary fuel as a reducing agent to an exhaust aftertreatment system, with the secondary fuel being able to be provided to the exhaust aftertreatment system directly by the reforming device and/or from the secondary fuel store.
