翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク High-temperature electrolysis ： ウィキペディア英語版 High-temperature electrolysis High-temperature electrolysis (also HTE or steam electrolysis) is a method being investigated for the production of hydrogen from water with oxygen as a by-product. ==Efficiency== High temperature electrolysis is more efficient economically than traditional room-temperature electrolysis because some of the energy is supplied as heat, which is cheaper than electricity, and also because the electrolysis reaction is more efficient at higher temperatures. In fact, at 2500 °C, electrical input is unnecessary because water breaks down to hydrogen and oxygen through thermolysis. Such temperatures are impractical; proposed HTE systems operate between 100 °C and 850 °C.〔(Hi2h2 - High temperature electrolysis using SOEC )〕〔(WELTEMP-Water electrolysis at elevated temperatures )〕 The efficiency improvement of high-temperature electrolysis is best appreciated by assuming that the electricity used comes from a heat engine, and then considering the amount of heat energy necessary to produce one kg hydrogen (141.86 megajoules), both in the HTE process itself and also in producing the electricity used. At 100 °C, 350 megajoules of thermal energy are required (41% efficient). At 850 °C, 225 megajoules are required (64% efficient). 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「High-temperature electrolysis」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.
