So far, as a part of NaBH<sub>4</sub>-H<sub>2</sub>-Fuel Cell study we have been through optimization of hydrogen production reactor size and operating conditions to reach 100% of hydrogen production rate. Moreover, the potential of NaBH<sub>4</sub>-H<sub>2</sub>-Fuel Cells were verified by testing a 1000mL pressurebuffer for steady hydrogen supply under variable load conditions within maximum limit of 1.2kW. However, the buffer used gives rise to decreased energy density of the system due to its big size relatively to other components. Hence, minimized buffer volume under the limit of applied conditions is required to compact the system. In this study, the pressurebuffer volume which satisfies load following as well as compact size is found. Load following ability is approved as a result of hydrogen generation system operation, which has 325mL and 170mL buffer volume at 0°C and 20°C respectively within load variation of the average load 700W, peak load 1200W and 2 seconds of load cycle. Furthermore, NaBH<sub>4</sub>-H<sub>2</sub>-Fuel Cell's energy density is calculated. At last, all these come into the result that NaBH<sub>4</sub>-H<sub>2</sub>-Fuel Cell has high usefulnessas a high density mobile power source over 2.7kWh.
