Chemical hydride hydrogen reactor and generation system

A system for generating hydrogen from a hydride solution in presence of a catalyst, the system comprising:

• a) a reactor vessel defining a reaction chamber and a coolant chamber, the reaction chamber being configured to bring at least a portion of the hydride solution in contact with the catalyst, the coolant chamber being located proximate to the reaction chamber for cooling of the hydride solution;
• b) a solution supply means for delivering the hydride solution to the reaction chamber, the solution supply means being in fluid communication with the reaction chamber;
• and
• c) a coolant supply means for delivering a coolant flow to the coolant chamber, the coolant supply means being in fluid communication with the coolant chamber;
• wherein the coolant supply means is configured to control at least one of the flow rate and the temperature of the coolant flow through the coolant chamber, thereby improving control of the temperature of the hydride solution in the reaction chamber.

A system for generating hydrogen from a hydride solution in presence of a catalyst, the system comprising:

• a) a solution supply means for supplying the hydride solution;
• b) a coolant supply means for supplying a coolant flow;
• and
• c) a reactor vessel defining a reaction chamber and a coolant chamber, the reaction chamber being in fluid communication with the solution supply means, the reaction chamber being configured to bring at least a portion of the hydride solution received from the solution supply means in contact with the catalyst, the coolant chamber being in fluid communication with the coolant supply means;
• and
• at least one reactor plate having a first face and a second face in opposing relation with the first face, wherein the first face defines a portion of the reaction chamber and the second face defines a portion of the coolant chamber.

A method of generating hydrogen comprising the steps of:

• a) contacting a catalyst with a hydride solution;
• and
• b) providing a coolant flow proximate to the hydride solution for controlling the temperature thereof;
• c) controlling at least one of the temperature and the flow rate of the coolant flow to improve temperature control of the hydride solution in contact with the catalyst.
