Treating an at least partially unconsumed hydrogen generator cartridge

A method of treating an at least partially unconsumed hydrogen generator cartridge comprising water and a metal hydride, the method comprising:

• treating the at least partially unconsumed hydrogen generator cartridge comprising removing the water from the hydrogen generator cartridge,
• adding a chemical barrier to the metal hydride as a physical barrier to slow or prevent further reaction of the metal hydride,
• dissolving the metal hydride in a solvent comprising tetrahydrofuran, a (C1-C10) alcohol, ethyl acetate, a di(C1-C10)alkyl ether, benzene, toluene, or a combination thereof, and removing the solvent from the cartridge,
• reacting the metal hydride with a protic solvent in a non-reactive miscible solvent, reacting the metal hydride with tetrahydrofuran, a (C1-C10) alcohol, ethyl acetate, or a combination thereof,
• reacting the metal hydride with a reactive gas or vapor comprising a (C1-C10) alcohol, or a combination thereof,
• reacting the metal hydride with a metal hydride poison,
• heating the metal hydride to decompose the metal hydride,
• or a combination thereof,
• to form a treated hydrogen generator cartridge;
• wherein when subjected to testing conditions the treated hydrogen generator cartridge produces no hydrogen gas or produces hydrogen gas at a lower rate than the at least partially unconsumed hydrogen generator cartridge subjected to the testing conditions, and wherein the testing conditions comprise heating at less than or equal to 300° C., agitation, exposing the metal hydride to a protic solvent, or a combination thereof.
