Abstract
Official abstract text for this publication.
Systems, devices, and methods combine thermally stable reactant materials and aqueous solutions to generate hydrogen and a non-toxic liquid by-product. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Springs and other pressurization mechanisms pressurize and deliver an aqueous solution to the reaction. A check valve and other pressure regulation mechanisms regulate the pressure of the aqueous solution delivered to the reactant fuel material in the reactor based upon characteristics of the pressurization mechanisms and can regulate the pressure of the delivered aqueous solution as a steady decay associated with the pressurization force. The pressure regulation mechanism can also prevent hydrogen gas from deflecting the pressure regulation mechanism.
First claim
Opening claim text (preview).
The claimed invention is: 1. A method of generating hydrogen gas, the method comprising: imparting a force on a solution chamber with a spring to pressurize an aqueous solution contained in the solution chamber; delivering the pressurized aqueous solution with a water feed system via a solution inlet fill port to a reactant material contained in a reactor to form a mixture comprising aqueous solution and reactant material that reacts to generate hydrogen gas; and, routing the ge…
