A pyrolytic hydrogen generator comprising a pressure vessel containing a plurality of cardboard receptacles for the thermally decomposable hydrogen generating material and an associated ignition system. Also, a modular pellet tray assembly for use in the generator comprises a plurality of trays having pellet holders and associated igniters and held in a stack by support rods that also provide electrical connectivity to the trays.

Hydrogen generators

A pyrolytic hydrogen generator comprising a pressure vessel containing a plurality of cardboard receptacles for the thermally decomposable hydrogen generating material and an associated ignition system. Also, a modular pellet tray assembly for use in the generator comprises a plurality of trays having pellet holders and associated igniters and held in a stack by support rods that also provide electrical connectivity to the trays. Also, a pellet tray assembly comprises a plurality of pellet holders, wherein some of more outwardly disposed pellet holders contain only outwardly facing vents and are fired first. Also, the generator has an array of hydrogen generating elements arranged side by side and separated from one another into cells by partitioning provided with directional venting that only permits laterally exiting gases to vent outwardly. Alternatively, the elements can be separated into cells by a baffle system comprising gas confining and gas venting elements, which may be heat conductive.

A hydrogen generator includes a plurality of fuel sticks each of which includes a hydrogen release compound configured to generate hydrogen by a chemical reaction, a pressure-resistant container configured to store therein the plurality of fuel sticks, and a controller configured to carry out control in such a manner that hydrogen is generated selectively from the plurality of fuel sticks.

Hydrogen generator and fuel stick

A man portable hydrogen source, the source comprising one or more hydrogen generating elements, an ignition control system and a pressure vessel. Each hydrogen generating element comprises a pellet holder provided with one or more recesses and a thermal insulation layer to reduce heat transfer to adjacent hydrogen generating elements; wherein at least one recess contains a pellet of a chemical mixture which on thermal decomposition evolves hydrogen gas; wherein the ignition control system comprises one or more igniters, associated with an individual pellet, and activation means to activate the igniters; and wherein the evolved hydrogen and hydrogen generating elements are contained within the pressure vessel.
