专利汇可以提供Redox flow battery专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent oxidation of active material in electrolytic solution by comprising a pipe-type member that connects a cell for moving the electrolyte to positive and negative liquid tanks with the plastic material whose oxygen transmission coefficient is regulated. CONSTITUTION:A redox flow battery permits positive and negative electrode cells 1a and 1b separated by an ion exchange membrane 2 to supply and exhaust an electrolytic solution to and from electrolytic tanks 11, 12, 21, and 22. In this case, pipe-shaped members 15a, 15b, 25a, and 25b that connect the tanks 11, 12, 21, and 22 to a cell 1 are comprised with the plastic material such as polyvinylidene chloride and poly-4-ethylene fluoride whose oxygen transmission coefficient is 5.0X10 cc.cm/(sec.cm .cmHg) or less. As a result, when external oxygen reacts with the active material in the electrolytic solution, the amount of active material can be prevented from being reduced and battery efficiency can be improved.,下面是Redox flow battery专利的具体信息内容。
