Development of Light-Weight Fuel Cell Electric Vehicle without High-pressure Hydrogen Tank

本研究开发了一种以粉末硼氢化钠为燃料的车载制氢系统。该系统可以连续产生氢气。此外，对永磁同步电机的控制方案进行了研究，开发了逆变器与燃料电池或双电层电容器连接的DC-DC转换器。此外，将燃料电池和逆变器之间的氢气发电系统、燃料电池和DC-DC转换器安装在轻型电动汽车上，取代了高压电池，并成功地进行了试驾。

An on-vehicle hydrogen generation system fueled by powdered sodium borohydride was developed in this research. The system can generate hydrogen continuously. In addition, control schemes for permanent magnet synchronous motor were investigated and dc-dc converters which were connected between inverter and fuel cell or electric double layer capacitor were developed. Moreover, the hydrogen generation system, fuel cell, and dc-dc converter connected between fuel cell and inverter were mounted on a light-weight electric vehicle instead of high voltage battery and the test driving were successful.
