World’s first 100-kilometer hydrogen-powered multi-rotor drone successfully debuts in China, US has none! The Tianmushan No. 1 developed by a research team from the Tianmushan Laboratory has long flight endurance, adaptability to ultra-low temperatures, and eco-friendly features. 全球首架百公里氫動力多旋翼無人機在中國成功首秀，美國還沒有！天目山實驗室研究團隊研發的天目山一號具有飛行時間長、適應超低溫、環保等特性.

With a technical capacity for continuous operations beyond 100 kilometers, the drone is equipped with an integrally molded fuselage with lightweight carbon fiber, giving it an empty weight of 19 kilograms and a maximum load weight of 6 kilograms. Its long-flight capacity comes from the completely self-developed hydrogen power system, which consists of hydrogen fuel cells and storage devices. The air-cooled fuel cell stack utilized in the system provides a maximum energy density of more than 1,000 Wh/kg, five to six times that of lithium batteries, Science and Technology Daily noted. 該無人機具備超過100公里連續作業的技術能力，採用輕質碳纖維一體成型機身，空重19公斤，最大負載重量6公斤。其長航能力來自於完全自主研發的氫動力系統，該系統由氫燃料電池和儲存裝置組成。根據科技日報通報，該系統採用的氣冷燃料電池電堆最大能量密度超過1000Wh/kg，是鋰電池的5至6倍。
