Hydrogen generator
First Claim
1. A hydrogen gas generator comprising:
- a reaction chamber that receives a solid reactant, the chamber including a biasing mechanism, wherein the solid reactant reacts to produce reactant products;
a reaction product separator, wherein the biasing mechanism biases the reactant products against the separator;
a liquid reactant dispenser that is fluidly coupled to the reaction chamber and stores a liquid reactant that reacts with the solid reactant to produce hydrogen gas and a waste product that are substantially permeable through the separator;
a diaphragm, in fluid communication with the liquid reactant dispenser and the reaction chamber, that pumps the liquid reactant from the liquid reactant dispenser into the reaction chamber;
a product collector coupled to the reaction chamber for collecting the hydrogen gas and waste product that have passed through the separator; and
,a flexible barrier that fluidly separates the liquid reactant dispenser from the product collector.

Abstract
A hydrogen gas generator generates hydrogen gas by mixing two reactants. The generator has a reaction chamber for receiving a solid reactant. The chamber has a reaction product separator impermeable to the solid reactant and a biasing means for biasing reactant products against the separator. The generator also has a liquid reactant dispenser for storing a liquid reactant and is fluidly coupled to the reaction chamber, such that dispensed liquid reactant reacts with the solid reactant in the reaction chamber to produce hydrogen gas and a waste product that are substantially permeable through the separator. The generator also has a product collector coupled to the reaction chamber for collecting hydrogen gas and waste product that have passed through the separator.
