據fuelcellworks網站報道，美國西北太平洋國家實驗室(PNNL)開kai發fa了le一yi種zhong新xin型xing的de鎳nie基ji催cui化hua劑ji。這zhe種zhong催cui化hua劑ji可ke以yi使shi電dian子zi和he質zhi子zi結jie合he形xing成cheng氫qing分fen子zi，以yi較jiao小xiao的de體ti積ji儲chu存cun能neng量liang。而er在zai需xu要yao能neng量liang時shi，催cui化hua劑ji破po壞huai氫qing分fen子zi中zhong的de單dan鍵jian並bing釋shi放fang能neng量liang。
