low overpotentialとは 意味・読み方・使い方

To provide an electrode for generating hydrogen which has sufficiently low hydrogen overpotential, is not poisoned by iron ions, further does not increase the hydrogen overpotential and does not drop a carried substance therein even during operation and when starting/stopping electrolysis, and has superior durability; a method for manufacturing the electrode for generating hydrogen; and an electrolysis method using the electrode for generating hydrogen as a cathode.例文帳に追加

水素過電圧が十分に低く、且つ、鉄イオンによる被毒の影響がなく、さらに、運転中や起動・停止中にも水素過電圧の上昇や担持物の脱落がなく耐久性に優れた水素発生用電極、該水素発生電極の製造方法、並びに、該水素発生用電極を陰極に用いた電解方法を提供する。 - 特許庁

In the fuel cell system 100, when the fuel cell 10 is started at low temperature of 0 (°C) or less, while a control unit 50 supplies a fixed amount of hydrogen to an anode 14, it restricts a supply amount of air to a cathode 16 so that a concentration overpotential of the fuel cell 10 becomes a higher value than that in normal starting process.例文帳に追加

燃料電池システム１００において、制御ユニット５０は、燃料電池１０の温度が０（℃）以下である低温起動時に、一定量の水素をアノード１４に供給しつつ、カソード１６への空気の供給量を、燃料電池１０の濃度過電圧が通常起動処理時よりも高くなる値に制限する。 - 特許庁
