摘要
介绍了一种特殊结构的锌空气电池。空气极是拼接而成的,面积可达到5 m2;单电池是没有密封部件的开放结构,方便燃料锌和生成物氧化锌的更换;单电池输出功率5 kW,大大减少了组成电站的电池个数。该电站在电网负荷高时通过电池组向电网送电,在用电低谷时电解氧化锌蓄能填谷,能量转换效率为42％～52％,且转换效率与电站规模无关,无污染,无噪声。
A novel structure of zinc-air cell is described. The area of the air electrode is as large as 5 m2 by splicing. To facilitate replacement of the fuel zinc and product ZnC), the single cell is designed in open structure without a seal part. It greatly reduces the number of cells in a power station because the output of one cell is 5 kW. The cell stacks supply power during the peak time of the network load and electrolyzes ZnO to store energy at the trough time. The energy efficiency is about 42%-52% and independent of the scale of the station. This kind of power station is free from pollution and noise.
