A method of making a package for a fuel unit, a fuel unit including the package, and a hydrogen generator including one or more of the fuel units are disclosed. The package includes a package strip made by forming apertures in a nonconductive substrate strip, forming conductor sections in a conductor strip, aligning the substrate and conductor strips, bonding the conductor sections to the substrate strip to cover the apertures, and removing non-bonded portions of the conductor strip. A package enclosing a hydrogen generating reactant is formed by securing a segment of the package strip to itself, to one or more other segments and/or to one or more other package components. One or more conductor sections in the package strip are in thermal contact with one or more quantities of reactant composition so heat can be transferred thermally decompose the reactant composition and generate hydrogen gas.

1. A method of making a package for a hydrogen generator fuel unit, the method comprising the steps: (a) providing a substrate strip made of an electrically nonconductive material with a thermal conductivity less than 10 watts/meter⋅Kelvin;(b) forming an array of apertures in the substrate strip;(c) providing a conductor strip made of an electrically conductive material with a thermal conductivity greater than 10 watts/meter⋅Kelvin;(d) forming an array of conductor sections in the conductor strip;(e) aligning individual conductor sections in the conductor strip with apertures in the substrate strip;(f) bonding a peripheral portion of each of the individual conductor sections to a portion of the substrate strip surrounding one or more of the apertures to form a bonded strip; and(g) removing nonbonded portions of the conductor strip from around the bonded conductor sections of the bonded strip to form a package strip;(h) providing an array of compartments, each compartment including a reactant composition; and(i) securing the package strip to the array of compartments to form the package for the hydrogen generator unit. 2. The method according to claim 1, wherein the substrate strip is made from at least one high temperature polymer, the high temperature polymer having a heat distortion temperature, per ASTM D648 at 18.56 kg/cm2, of at least 250° C. 3. The method according to claim 2, wherein the at least one high temperature polymer comprises two or more high temperature polymers. 4. The method according to 2, wherein the at least one high temperature polymer comprises polymer selected from polyetheretherketone, polyimides, phenolics, and derivatives thereof. 5. The method according to claim 1, wherein the conductor strip is made from a material selected from metals, metal alloys and non-metallic materials. 6. The method according to claim 1, wherein at least one of the substrate strip, the conductor strip and the package strip is provided in a roll. 7. The method according to claim 1, wherein the package strip is cut into segments for a subsequent batch process. 8. The method according to claim 1, wherein the array of apertures comprises apertures arranged in at least one longitudinal row extending parallel to a longitudinal axis of the substrate strip. 9. The method according to claim 1, wherein the substrate strip and the conductor strip have registration features for aligning the individual conductor sections in the conductor strip with the corresponding apertures in the substrate strip. 10. The method according to claim 1, wherein the step of forming an array of conductor sections in the conductor strip comprises creating weak areas around the conductor sections to facilitate removing nonbonded portions of the conductor strip from around the bonded conductor sections of the bonded strip. 11. The method according to claim 10, wherein the weak areas comprises one or more of narrow bands connecting the conductor sections to surrounding conductor strip, and coined areas between the conductor sections and surrounding conductor strip. 12. The method according to claim 1, wherein the step of forming an array of conductor sections in the conductor strip comprises removing some portions of the conductor strip around the conductor sections and leaving a non-bonded web of conductor strip material connected to the conductor sections. 13. The method according to claim 12, wherein the non-bonded web of conductor strip material is removed by breaking the web near the conductor sections to disconnect the web from the conductor sections and separating the disconnected web from the remainder of the bonded strip. 14. The method according to claim 1, wherein the step of removing nonbonded portions of the conductor strip from around the bonded conductor sections of the bonded strip is performed while a bonding tool is in contact with the conductor strip. 15. The method according to any one of the preceding claims, wherein more than one aperture is covered by a single conductive section. 16. The method according to claim 15, wherein after bonding a peripheral portion of each of the individual conductor sections to a portion of the substrate strip surrounding each of the corresponding apertures, a portion of the conductor material between adjacent apertures covered by the single conductive section is removed so each of the apertures that was covered by a single conductive section is covered by a separate conductive section. 17. The method according to claim 1, wherein the substrate strip and the conductor strip are aligned with their longitudinal axes parallel to each other. 18. The method according to any one of claim 1, wherein the substrate strip and the conductor strip are aligned with their longitudinal axes perpendicular to each other during bonding.
