Abstract:
A hydrogen gas generating apparatus for providing hydrogen gas to a fuel cell stack is provided. The apparatus includes an expandable reaction chamber containing a solid reactant component and a collapsible receptacle containing a liquid reactant component with a housing. The reaction chamber includes an expandable reactant zone defined by a moveable partition that retains the reactants and reaction products within the reaction chamber. The apparatus also includes a liquid transport control system and a fluid path for transporting the liquid reactant component from the collapsible receptacle to the reactant zone in the reaction chamber, where the liquid and solid reactant components react to generate hydrogen gas. The receptacle collapses with a corresponding expansion of the reaction chamber as liquid reactant component is used, and the reactant zone expands within the reaction chamber in response to pressure from the increasing volume of reaction products on the moveable partition. Volume exchange among the expandable reaction chamber, the expandable reactant zone and the collapsible receptacle provides a high volume of hydrogen gas from a hydrogen generating apparatus of limited volume.
