In the second exothermic step cerium(III) oxide reacts at – in a fixed bed reactor with water and produces hydrogen and cerium(IV) oxide. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cerium(IV) oxide–cerium(III) oxide cycle」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
