Abstract
The present invention relates to a monopropellant system for a regenerative fuel cell (RFC) and a method for mono-propulsion using same and, more specifically, to a monopropellant system for an RFC which can, when operating an electrically propelled airplane adopting an RFC system, secure more energy via a monopropellant than conventional methods and use same as a propulsion source for airplane takeoff and so on, and to a method for mono-propulsion using the monopropellant system for an RFC.
Claims4
A monopropellant flying system comprising:
- (1) a power supply configured to supply electricity:
- (2) a fuel cell configured to use hydrogen and oxygen to generate electricity and water as byproduct;
- (3) a propeller configured to use electricity from the power supply and/or the fuel cell;
- (4) a storage configured to store a monopropellant and further configured to receive the water from the fuel cell such that, upon receiving water from the fuel cell, the monopropellant is mixed with the water in the storage;
- and
- (5) a propulsion device configured to use the monopropellant or a mixture of the monopropellant and water from the storage to generate propulsion force at the time of take-off.
