The hydrogengas could then be fed into a storage system and used to generate electricity when additional or backup power is needed.
然后可以将氢气输入到存储系统中，并在需要附加或备用电源时用于发电。

Combined with another catalyst, such as platinum, that can produce hydrogengas from water, the system can duplicate the water splitting reaction that occurs during photosynthesis.
结合上其他从水中产生氢气的催化剂如铂，这个系统就能复制在光合作用中所发生的水分解反应。
