A fluid-jet precision-dispensing device includes a layer, one or more first holes within the layer, and one or more second holes within the layer. The first holes are adapted to pass fluid therethrough during usage of the device to precisely dispense the fluid at accurately specified locations. The second holes are adapted to not pass the fluid therethrough during usage of the device to precisely dispense the fluid at the accurately specified locations. The second holes may be adapted to at least substantially maximally pass gaseous bubbles therethrough during performance of a priming operation of the device. The second holes may be adapted to at least substantially maximally pass sludge and/or contaminants therethrough during performance of the priming operation of the device.

A hydrogen generation cartridge preferably includes a munitions casing, a hydrogen producing chemical reactant within the casing, and an outlet for releasing hydrogen produced in the casing. A portable hydrogen generator preferably includes a chamber for receiving a plurality of hydrogen generation cartridges, and control electronics for selectively operating the hydrogen generation cartridges in the chamber. The cartridges individually produce hydrogen under control of the control electronics.
