摘要
研究甲醇浓度、甲醇溶液温度、电池温度以及阴极空气状态对被动式直接甲醇燃料电池电化学性能的影响。结果表明,在常压条件下,甲醇浓度、甲醇溶液温度、阴极空气状态以及电池温度对电池性能存在着明显的影响。被动式直接甲醇燃料电池最佳甲醇浓度为1.5mol/L,电池性能随着甲醇溶液温度和电池温度的上升而迅速提高,阴极空气状态的改变也有利于电池性能的提高。
The effects of methanol concentration, methanol temperature, cell temperature and air state on the performance of self-installed passive DMFC are investigated. The results show that there are the significantly effects of methanol concentration, methanol temperature, cell temperature and air state on the performance of the passive DMFC at ambient atmosphere. The optimal methanol concentration in cell is 1.5mol/L. The cell performance is increased with the increase of the temperature of methanol and cell. The change of air state is also propitious to the performance of cell.
