Abstract
A hydrogen generation system includes a fuel container, a spent fuel container, a catalyst system and a control system for generating hydrogen in a manner which provides for a compact and efficient construction while producing hydrogen from a reaction involving a hydride solution such as sodium borohydride.
Claims35
A hydrogen generator system comprising:
- a first container, said first container having at least one side;
- a second container, said second container having at least one side;
- a catalyst system, said catalyst system being in fluid communication with said first container and said second container;
- a pumping system, said pumping system being in fluid communication with said catalyst system;
- wherein at least a portion of said at least one side of said first container is shared with at least a portion of said at least one side of said second container thereby defining a shared partition, and
- wherein at least a portion of said shared partition is flexible.
3 more elements
A hydrogen generator system comprising:
- a first container, said first container having at least one side;
- a second container, said second container having at least one side, wherein said second container is contained at least partially within said first container, and wherein at least a portion of said at least one side of said second container is outside said first container, thereby defining an outside portion;
- a catalyst system, said catalyst system being in fluid communication with said first container and said second container;
- a pumping system, said pumping system being in fluid communication with said catalyst system;
- and
- a spent fuel line, said spent fuel line being in fluid communication with said catalyst system and at least a portion of said spent fuel line being wrapped around at least a portion of said outside portion of said second container.
3 more elements
A hydrogen generator system comprising:
- a first container;
- a second container;
- a catalyst system, said catalyst system being in fluid communication with said first container and said second container;
- a pumping system, said pumping system being in fluid communication with said catalyst system;
- and
- a spent fuel line, said spent fuel line being in fluid communication with said catalyst system and at least a portion of said spent fuel line being wrapped around at least a portion of said outside portion of said second container,
- wherein said catalyst system and said pumping system are disposed between said first container and said second container.
4 more elements
Apparatus for use in a system for generating hydrogen, said apparatus comprising
- a first container containing a reactant material capable of generating hydrogen and a spent material, said first container also having an exit port which provides said reactant material;
- and
- a second container configured to receive said hydrogen and said spent material generated by said reactant material, said first and second containers sharing a common portion and wherein said common portion responds to reactant material exiting through said exit port so as to decrease the volume of said first container and increase the volume of said second container, and said second container having an output port configured to output said hydrogen.
A method for use in a system for generating hydrogen, said method comprising the steps of
- providing a first container containing a reactant material capable of generating hydrogen and a spent material, said first container also having an exit port which provides said reactant material;
- and
- providing a second container configured to receive said hydrogen and said spent material generated by said reactant material, said first and second containers sharing a common portion and wherein said common portion responds to reactant material exiting through said exit port so as to decrease the volume of said first container and increase the volume of said second container, and said second container having an output port configured to output said hydrogen.
