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.
A hydrogen source comprising one or more hydrogen generating elements arranged in a pressure vessel and an ignition control system associated with the hydrogen generating element(s), wherein the one or more hydrogen generating elements comprise a plurality of pellets of an ignitable chemical mixture that on thermal decomposition evolve hydrogen gas, wherein the ignition control system comprises a plurality of ignitors arranged to ignite the pellets on an individual basis, and wherein the ignition control system is arranged to control the rate of ignition of the pellets.
A hydrogen source comprising one or more hydrogen generating elements arranged in a pressure vessel and an ignition control system associated with the hydrogen generating element(s), wherein the one or more hydrogen generating elements comprise a plurality of pellets of an ignitable chemical mixture that on thermal decomposition evolve hydrogen gas, wherein the ignition control system is arranged to control the rate of ignition of the pellets, and wherein the ignition control system comprises a plurality of ignitors, one or more ignitors being associated with each individual pellet to permit successive or simultaneous ignition of pellets in a controllable manner.
A hydrogen source comprising one or more hydrogen generating elements arranged in a pressure vessel and an ignition control system associated with the hydrogen generating element(s), wherein the one or more hydrogen generating elements comprise a plurality of pellets of an ignitable chemical mixture that on thermal decomposition evolve hydrogen gas, wherein the ignition control system comprises a plurality of ignitors arranged to ignite the pellets on an individual basis and the pellets are sufficiently spaced or separated from one another to prevent cross-ignition, and wherein the ignition control system is arranged to control the rate of ignition of the pellets.
