NOVELTY - A hydrogen generation system comprises cartridge(s) containing anhydrous hydride reactant, liquid conduit(s) having liquid distribution aperture(s), a cartridge receiver including passages corresponding to gas outlet port(s) and liquid inlet port(s) on the cartridge, and a liquid reactant injection control system reading reaction parameter(s) and adjusting amount of liquid reactant injected from distribution aperture based on reactant parameter.    USE - For producing hydrogen from chemical hydride.    DETAILED DESCRIPTION - A hydrogen generation system comprises cartridge(s) containing anhydrous hydride reactant and having liquid inlet port(s) and gas outlet port(s), liquid conduit(s) extending into the cartridge and having liquid distribution aperture(s), a cartridge receiver removably engaging the cartridge and including passages corresponding to the gas outlet port and liquid inlet port, and a liquid reactant injection control system connected to the cartridge receiver. The control system reads reaction parameter(s) and adjusts an amount of liquid reactant injected from the distribution aperture based on the reactant parameter.    An INDEPENDENT CLAIM is also included for a fuel cartridge for hydrogen generating system, comprising a cartridge having an end cap (12, 15) and containing a bed of anhydrous hydride reactant, and liquid conduit(s) (30) fixed to the end cap, extending into the bed and having liquid distribution aperture(s) (32) with a diameter of 50-1,000 microns so that liquid reactant may pass in liquid form into the bed of hydride reactant. The end cap has a liquid inlet port (21) connected with the liquid conduit, and a gas outlet port (20). Both liquid inlet port and gas outlet port are adapted to seal with a cartridge receiver.    DESCRIPTION OF DRAWING(S) - The figure shows a hydrogen fuel cartridge.
