Abstract
A hybrid power and propulsion generation system for a marine vessel is provided that combines a fuel cell with a wave rotor/combustor. A wave rotor that uses gas dynamics (shock and expansion) processes within rotating passages, using a hydrogen and oxygen supply in fluid communication with the wave rotor, is combined with a regenerative fuel cell for power generation for an underwater vessel.

An apparatus for a hybrid power generation system for a marine vessel comprising:
- a fuel cell for powering said marine vessel when a low speed is required by said marine vessel;
- and
- a wave rotor for powering said marine vessel in combination with said fuel cell when a high speed is required by said marine vessel.
A hybrid power generation method for a marine vessel, the method comprising:
- powering a motor of said marine vessel by a fuel cell when a low speed is required by said marine vessel;
- and
- powering a motor of said marine vessel by a wave rotor in combination with said fuel cell when a high speed is required by said marine vessel.
A hybrid propulsion system for a marine vessel comprising:
- a fuel cell for powering said marine vessel when a low speed is required by said marine vessel;
- and
- a wave rotor for powering said marine vessel in combination with said fuel cell when a high speed is required by said marine vessel.
