Beschreibung
Zusammenfassung:	A disposable, compact, and efficient storage apparatus (10) contains a fuel source (24) and water for supplying hydrogen fuel (36) to a micro-fuel cell. The storage apparatus comprises a housing defining a fuel source chamber (14) and a plurality of water chambers (12), and one or more polymer crystals (22) containing water positioned within each of the water chambers (12). The fuel source (24), such as a chemical hydride mixed with a catalyst, is positioned within the fuel source chamber (14), wherein the water in each of the water chambers (12) is selectively allowed to migrate to the fuel source chamber (14) to contact the solid fuel, thereby producing the hydrogen fuel (36) at a desired flow rate and temperature. A conduit (32) supplies the hydrogen fuel (36) produced within the housing to the fuel cell (38).
