| Summary: | 碩士 === 元智大學 === 機械工程學系 === 105 === The lightweight unmanned aerial vehicle (UAV), integrated network of things, artificial intelligence, sensors and new energy technologies, is one of the future innovation industry, which can be applied to the military, commercial and entertainment industry. Such as aerial photography, agriculture, environmental and traffic monitoring VAV machines, and the most critical future network transport service UAV. Among them, the energy technology, how to use fuel cells to extend flight time can be more practical for the logistics industry and long-time detection applications.
The high power density of fuel cell module (> 500W / Kg) and the high energy density of hydrogen storage technology (> 5wt%) are required in the range of 50 ~ 300W for the modularized fuel cell power system. Although the current fuel cell vehicle technology has exceeded this specification, but in the small watt system, there is no mature commercial fuel cell technology and products. The membrane electrodes used in open cathode stacks and required high-performance at low-humidity environments, which are used in prototypes of companies such as Intelligent Energy EnergyOR, Horizon fuel cell Tech., Etc. or literatures. In addition to reducing the size of the power pack and system, it also need to reduce its weight and costs of parts. This technology and products also may be applied to other portable power and lightweight mobile carriers.
The goal of the project is to build a research and development platform for this unmanned fuel cell stack and component technology, integrating parts and systems technology from Taiwan’s academic and industrial technology to enhance the power density, stability and longevity of UAV applications. A collection of personal expertise in the low-temperature diffusion layer and fuel cell technology, as well as industry components such as carbon energy technology Co. of carbon paper and Yang-ze Tech.CO. of membrane electrode assemblies, and the Asia-Pacific fuel cell technology Co. on the fuel cell stack and system experience, used in this high-performance open cathode type fuel cell stack design. The first year, the establishment of open cathode stack design, and testing of domestic and foreign component materials, so that the fuel cell power density can be up to 300W / Kg. The next year, the improved fuel cell stack and system design, has high performance, stability and life time, and also improved material component technology to have optimized stable power performance> 500 W / Kg, and its low humidity MEA has power density of 500mW / cm2.
