摘要 对自行设计的被动式自呼吸直接甲醇燃料电池进行了动态性能实验,分别测试了循环加载/卸载、不同卸载时间、方波脉冲加载以及阶梯加载等多种加载方式中电池的电压和温度响应。实验结果表明:电池的电压和温度对各种负载变化均响应迅速;加载/卸载循环中卸载时间的长短对电池的电压和温度响应影响较大;电池电压和温度在上/下阶梯加载中的响应有所不同。 The experiments on the dynamic performance of a home-made passive direct methanol fuel cell （DMFC） were carried out.The dynamic response of cell voltage and temperature under different loading/unloading circle were investigated,and the effects of unloading time,loading modes including square-wave pulse load,step load,and step load plus high frequency pulse load were analyzed.The experimental results show that the cell voltage and temperature responds rapidly in all loading circle modes.The unloading period in the circle has a significant influence on the cell voltage and temperature dynamic responds,which shows different behaviors in step loading and step unloading.
