NOVELTY - The system has a refillable hydrogen reservoir (12) containing hydrogen in a form, a converter converting the form of hydrogen to hydrogen gas, and another hydrogen reservoir (14) comprising a hydrogen occluding material. A hydrogen transfer interface i.e. device fueling interface (26), including a portable device fluidic coupling is in fluid communication with the latter hydrogen reservoir, where the system is devoid of multiple compressors for compressing hydrogen. The hydrogen occluding material is one of reversible metal hydride, zeolite and carbon based hydrogen occluding material.    USE - Hydrogen supply system for supplying hydrogen to a portable electronic device e.g. hydrogen fuel cell powered electronic device. Uses include but are not limited to music player, media player, global positioning system, portable phone e.g. mobile phone, satellite telephone, radiotelephone and portable telephone handset, compact disk (CD) player, portable computer, ultra-mobile computer, electronic game, personal digital assistant (PDA) and power tool.    ADVANTAGE - The refillable hydrogen reservoir includes a reasonably large mass of hydrogen in a convenient, safe and efficient manner. The hydrogen is transferred to the device in a facilitated manner by multiple synergies between a hydrogen-storing material in the hydrogen reservoir and another hydrogen-storing material in the device, where overall weight of the system can be reduced as the hydrogen-storing materials are not heavy. The latter hydrogen-storing material can filter impurities from the hydrogen before the hydrogen is transferred to the device. The system is simple and devoid of compressors, pumps and heavy, high-maintenance components. The hydrogen can be inexpensively, safely and conveniently introduced into the device.    DETAILED DESCRIPTION - The form of hydrogen is metal or metal alloy. The portable device fluidic coupling is selected from a group consisting of mechanical safety latch, pressure relief valve, pressure regulator, flow regulator, electrical connector and electrical power connector.
