Development of NaBH4-Based Hydrogen Generator for Fuel Cell Unmanned Aerial Vehicles with Movable Fuel Cartridge

NaBH4-based hydrogen generator for fuel cell Unmanned Aerial Vehicle (UAVs) with movable fuel cartridge was developed in the present study. The main fuel of hydrogen generator is Sodium borohydride (NaBH4) that is a kind of chemical hydride and has a high hydrogen storage density. In the previous studies, hydrogen generators were developed in which hydrogen was directly generated from solid state NaBH4. However, it was a prototype, so inconvenient to replace the fuel after used up and lacked user convenience. Therefore, the performance evaluation and the development procedure of NaBH4-based hydrogen generator that was designed taking user convenience in consideration for commercialization were described in this paper.
