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.
Claims43
A hydrogen generator comprising:
- a fuel container adapted to contain fluid reactants;
- a catalyst chamber in fluid communication with the fuel container, wherein the catalyst chamber is configured to catalyze reaction of the fluid reactants to produce reaction products comprising hydrogen and non-gaseous products;
- a spent fuel container adapted to receive the reaction products from the catalyst chamber;
- a pump configured to pump the fluid reactants from the fuel container through the catalyst chamber into the spent fuel container;
- and
- a hydrogen outlet in fluid communication with the spent fuel container;
- wherein at least a portion of the spent fuel container is configured to retain the non-gaseous products.

A hydrogen generator comprising:
- a fuel container containing a fuel capable of generating products comprising hydrogen and non-gaseous products, said fuel being one of a hydride solution and a stabilized metal hydride solution;
- a spent fuel container for retaining the non-gaseous products separate from the fuel;
- a catalyst chamber in fluid communication with the fuel container and the spent fuel container, wherein the catalyst chamber is configured to catalyze reaction of the fuel to produce reaction products comprising hydrogen and non-gaseous products;
- a pump means for pumping fluid from the fuel container through the catalyst chamber to the spent fuel container;
- and
- a hydrogen outlet in fluid communication with the spent fuel container;
- wherein at least a portion of the spent fuel container is configured to retain the non-gaseous products.
