1. A method of manufacturing a metal hydride fuel source that reduces fuel source expansion during fuel release, comprising: providing a first and a second malleable repository, each defining an open end and a closed end opposing the open end;depositing metal hydride powder into the first repository;encapsulating the metal hydride powder between the first and second repository by nesting the second repository with the first repository;applying a compressive force to the closed ends of the first and second deformable repositories, the compressive force sufficient to compress the powder into a substantially cohesive pellet; andencapsulating the pellet between the first repository and a cap and then nesting the second repository over the first repository such that the cap and the pellet are encapsulated between the first and second repositories. 2. The metal hydride fuel source of claim 1, wherein encapsulating the metal hydride powder further comprises sealing the metal hydride powder between the first and second repositories by folding an edge defining the open end of the second repository over the closed end of the first repository. 3. The metal hydride fuel source of claim 1, further comprising compacting and regrinding the metal hydride powder prior to depositing the metal hydride powder into the first repository. 4. The metal hydride fuel source of claim 1, wherein applying a compressive force to the closed ends of the first and second repository comprises compressing an uncompressed fuel source with a die press. 5. The metal hydride fuel source of claim 1, wherein the compressive force is sufficient to fuse one or more particulates of the metal hydride powder to the first repository. 6.
