Abstract
Hydrogen gas is generated on demand by reacting hydrochloric acid (haloacid) and a pure metal by flowing the acid upwardly through a bed of metal particles held on a distributor plate within a sliding tray. The tray reciprocates in a receiving vessel. A port in the retaining vessel can be aligned with a drain port in the sliding tray (below the distributor plate) so that the solution in the bed can be shunted directly to an annulus between the retaining vessel and the reactor jacket, thereby eliminating contact of acid and metal and stopping the generation of hydrogen. A coolant may be circulated in the base of the retaining vessel to control the temperature of the acid as it enters the bed, thereby helping to control the reaction rate. A hydrogen generator reactor includes one or more sliding trays housed within a jacket.
