铁-杂多酸液流电池的研究(英文)

STUDIES ON AN IRON HETEROPOLYACID REDOX FLOW BATTERY

本文报道的氧化还原流动池，负极活性物质为ＦｅＳＯ４，正极为Ｈ３ＰＭｏ１２Ｏ４０（ＨＰ）．具有选择性的阳离子交换膜将两个经活化的多孔碳毯电极分开，两个氧化还原电对在碳和石墨电极上都具有相适应的电化学可逆性．电池的活性物质很稳定。

This paper reports a new Fe HP redox flow cell. The positive and negative electrodes active materials are phosphomolybdic acid and acidified ferrous sulphate solutions respectively. Two activated porous carbon felt electrodes where the electrochemical reactions take place, are separated by a selective cation exchange membrane. The both couples have a suitable electrochemical reversibility on carbon and graphite electrodes. The active materials of the cell have very high stability. Moreover the cell has no life cycle limiting.
