Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 ハイブリッド自動車及び電車やエレベーター 等の短時間に繰り返し起動と停止を行うパワ−貯蔵装置 としての高出力バナジウムレドックス電池を提供するこ とにある。 【解決手段】 極室に電解液を封じて充放電を行う液静 止型バナジウムレドックス電池において、電解液を保持 しうる伝導性の良い多孔性電極およびバナジウムイオン の電子交換反応活性の高い反応性電極からなる2層電極 を構成し、該多孔性電極はバイポーラ板側に、一方該反 応性電極はイオン交換膜側に配置することにより、電流 密度が10〜2500mA/cm 2 、単セルの電圧が1.70 V〜0Vの広い範囲に亙って急速な充放電を繰り返すこ とを可能にした。 (57) [Problem] To provide a high-output vanadium redox battery as a power storage device that repeatedly starts and stops a hybrid vehicle, a train, an elevator, and the like in a short time. SOLUTION: In a liquid stationary type vanadium redox battery in which an electrolyte is sealed in an electrode chamber and charged and discharged, a porous electrode having good conductivity capable of holding the electrolyte and a reactive electrode having a high electron exchange reaction activity of vanadium ions. By arranging the porous electrode on the bipolar plate side and the reactive electrode on the ion exchange membrane side, the current density is 10 to 2500 mA / cm 2 , and the voltage of the single cell is 1.70 Rapid repetition of charging and discharging over a wide range from V to 0 V is enabled.
