Abstract
A powertrain that operates with hydrogen includes a hydrogen tank, an internal combustion engine supplied with hydrogen by the hydrogen tank, and an electric motor operating from a fuel cell supplied with hydrogen from this hydrogen tank. The powertrain includes an air-circulation connection circuit provided with an opening/closing device and connecting an air outlet of the fuel cell to an air inlet of the internal combustion engine to allow oxygen-depleted air from the fuel cell to supply the internal combustion engine.

1-10. (canceled)
A powertrain operating with hydrogen, said powertrain comprising:
- a hydrogen tank;
- an internal combustion engine supplied with the hydrogen by said hydrogen tank;
- an electric motor operating from a fuel cell supplied with the hydrogen originating from the hydrogen tank;
- a first air-circulation circuit opening into an air inlet of the fuel cell so as to supply air to said fuel cell;
- and
- an air-circulation connecting circuit that is equipped with an opening/closing means and connects an air outlet of the fuel cell to an air inlet of the internal combustion engine in order to allow oxygen-depleted air originating from the fuel cell to supply the internal combustion engine, the internal combustion engine being supplied with air by a second air-circulation circuit.
