A fuel cartridge and a hydrogen generator are provided for supplying hydrogen gas to a hydrogen gas device. The fuel cartridge includes a fuel composition disposed in a container and a multi-layer package material, such as a laminate, enclosing the fuel composition therein. The laminate includes a polymer layer distal the fuel composition and a conductor layer proximate the fuel composition and including a preformed portion. The hydrogen generator includes a punch thermally coupled to a heater assembly and is configured to move between a retracted state and a puncture state. When the fuel cartridge is disposed in the hydrogen generating apparatus, the punch is configured to puncture the polymer layer and bring the coined portion into contact with the fuel composition. Heat is applied to a hydrogen containing material in the fuel composition through the punch and preformed portion to release hydrogen gas.

1. A method of generating hydrogen gas, comprising: inserting a fuel cartridge into a hydrogen generator, the hydrogen generator comprising a housing that houses a holder configured to retain the fuel cartridge, a heater assembly, and a punch thermally coupled to the heater assembly, and the fuel cartridge comprising: a container defining an interior volume and comprising an open portion;a fuel composition disposed within the interior volume of the container, the fuel composition comprising a hydrogen containing material configured to release hydrogen gas when heated; anda multi-layer package material at the open portion of the container and enclosing the fuel composition within the container;puncturing the multi-layer package material by moving the punch from a retracted state to a puncture state, wherein the puncture state of the punch provides a heat conductive path from the heat source to the surface of the fuel composition through the punch; andapplying heat to the fuel composition through the punch to release hydrogen gas from the hydrogen generating material. 2. The method of claim 1, wherein the multi-layer package material comprises: a conductor layer proximate the fuel composition, a portion of the conductor layer being a preformed portion; and,a polymer layer distal the fuel composition. 3. The method of claim 2, wherein the step of puncturing the multi-layer package material comprises puncturing the polymer layer, separating the preformed portion of the conductor layer from the remainder of the conductor layer, and bringing the preformed portion of the conductor layer into contact with the fuel composition. 4. The method of claim 2, wherein the step of puncturing the multi-layer package material comprises puncturing the polymer layer and bringing the preformed portion of the metal layer into contact with the fuel composition. 5. The method of claim 1, wherein the conductor layer comprises at least one of aluminum, copper, stainless steel, steel, or nickel; and,the polymer layer comprises polyether ether keytone. 6. The method of claim 5, wherein the fuel composition comprises multiple segregated portions disposed within the interior volume of the container, the conductor layer comprises multiple preformed portions, each preformed portion adjacent a respective segregated portion of the fuel composition, and the hydrogen generator comprises multiple punches, each punch arranged so as to be adjacent a respective segregated portion of a fuel composition within the fuel cartridge when the fuel cartridge is retained by the holder, and, wherein the step of puncturing the multi-layer package material comprises controlling one of the multiple punches to puncture one of the respective preformed portions.
