液流电池，钒电池交流
液流电池使用的质子交换膜主要有氟化聚合物膜、磺化聚苯醚膜、复合膜和生物膜。选择哪种膜取决于电池的工作条件、电压、能量和功率需求以及成本等因素。The main types of proton exchange membranes used in flow batteries include fluoropolymer membranes (such as Nafion membrane), sulfonated polysulfone membranes, composite membranes, and bio-membranes. The choice of membrane depends on the battery's operating conditions, voltage, energy and power demands, and cost considerations.
