NOVELTY - Apparatus (10) for storage and liberation of compressed hydrogen gas, comprises a storage tank (11) comprising arrays of hollow micro-cylinders (112); a pre-volume chamber (12) coupled to the storage tank (11); a hydrogen liberating tool (14) comprising heating coils (141) wound around the micro-cylinder ends (115) sealed with plugs (113); and configured for melting the plugs (113); and an adapter module (13) coupled to the pre-volume chamber (12) and configured for coupling the pre-volume chamber.    USE - The apparatus is useful for storage and liberation of compressed hydrogen gas (claimed).    ADVANTAGE - The apparatus demonstrates the flexibility of the technology allowing for the open scaling of arrays-in-size, length and number; easy linkage to a variety of fuel cells; and for the simple shaping of the device using a moldable polymer overwrap for the housing.    DETAILED DESCRIPTION - Apparatus (10) for storage and liberation of compressed hydrogen gas, comprises a storage tank (11) comprising arrays of hollow micro-cylinders (112) defining cavities storing compressed hydrogen gas, each micro-cylinder (112) having an end (115) sealed with a plug (113) made of an easily meltable alloy having a melting temperature lower than the melting temperature of the micro-cylinder material; a pre-volume chamber (12) coupled to the storage tank (11) such that the micro-cylinder ends (115) sealed with the plugs (113) are located within a volume of the pre-volume chamber (12); a hydrogen liberating tool (14) comprising heating coils (141) wound around the micro-cylinder ends (115) sealed with plugs (113); and configured for melting the plugs (113), thus to controllably liberate the hydrogen gas from the arrays of the micro-cylinders into the pre-volume chamber (12); and an adapter module (13) coupled to the pre-volume chamber (12) and configured for coupling the pre-volume chamber to a device utilizing the hydrogen gas stored in the storage tank (11) for supplying the hydrogen gas.
