小松：研發氫燃料電池挖掘機！
ー配備豐田FC系統和氫罐ー
小松為配備氫燃料電池的中型液壓挖掘機開發了一款概念車。
20噸重的車身配備了豐田的氫燃料電池系統和多個氫氣罐。
在小山工廠（栃木縣小山市）開始實證試驗。
除了這款氫燃料電池挖掘機，2022年10月還開發了一款20噸的電動挖掘機。
加快量產，減少工程機械作業現場二氧化碳氣體排放。

這款氫燃料電池挖掘機：
概念車的運營時間和車身尺寸沒有透露。
這輛 20 噸的卡車長 9.5 米，寬 2.8 米，高 3.1 米。
自主開發關鍵部件和控制技術，追求“與發動機驅動型相當的挖掘性能和可操作性”。

氫燃料電池挖掘機的優勢：
小鬆開發氫燃料電池挖掘機的主要原因是它可以在比 LiB 更短的時間內充滿氫燃料。
目前的鋰電池缺乏移動大型工程機械的動力。
如果增加電池的數量來增加輸出，充電時間會很長，而且不能在工地使用。
在深山工地作業的工程機械、礦山機械，需要24小時不間斷作業。

Developed a concept machine for a medium-sized hydraulic excavator equipped with a hydrogen fuel cell, and began PoC tests.
For the new concept machine, Komatsu adopted a hydrogen fuel cell system and hydrogen tank, which were produced by Toyota Motor Corporation (Operating Officer, President: Koji Sato) (hereafter “Toyota”), on Komatsu’s medium-sized hydraulic excavator.
In addition to Komatsu’s comprehensive control technology, the combination of Toyota’s hydrogen fuel cell system and Komatsu key components,
Komatsu is working toward zero exhaust emissions and a significant reduction in noise and vibration, while delivering the same powerful digging performance and high operability as engine-driven excavators.
Medium-sized and large construction equipment requires a power source with higher energy density than that of small construction equipment, which has led the move to electrification with batteries.
Because hydrogen has a higher energy density and can be refueled in a shorter time than recharging batteries, Komatsu has been advancing its R&D efforts as a promising electrification choice for medium-sized and large models.
To contribute to realizing a hydrogen society and carbon neutrality, Komatsu will continue its efforts toward the commercial production of medium-sized and large construction machinery equipped with hydrogen fuel cells by conducting PoC tests of this new concept machine.
