Claim Text:
1. A hydrogen gas generator comprising: a housing including a plurality of sidewalls and a rear wall, wherein the plurality of sidewalls and rear wall form a cavity configured to receive one or more fuel units; and a heater assembly configured to be at least partially housed within the cavity, the heater assembly comprising a support member, at least one heating element capable of converting electrical to thermal energy, and at least one temperature-sensitive actuator, the at least one heating element and temperature-sensitive actuator being disposed adjacent to one another, in a stacked arrangement with respect to the support member, and said actuator capable of transforming from a first dimensionally retracted state to a second dimensionally expanded state when heated by the at least one heating element, wherein the at least one actuator is in the first state when a temperature of the at least one actuator is below a first prescribed temperature and the at least one actuator is in the second state when a temperature of the at least one actuator is above a second prescribed temperature that is equal to or higher than the first prescribed temperature, and wherein at least one of the at least one heating element and or the at least one actuator is displaced closer in proximity to the one or more fuel units when the at least one actuator is in the second state than when the at least one actuator is in the first state.
