摘　　要：聚合物电解质膜燃料电池是绿色环保的能源利用技术,电池内部的水热平衡对电池性能至关重要。通过雾化冷却实验、非持续雾化实验、雾化激活电池实验,探究雾化对聚合物电解质膜燃料电池性能和寿命的影响。结果表明:与不使用雾化相比,100 mL/h的雾化量可以将电池内部平均温度降低10℃;非持性雾化后,在全工作电压范围内的电池性能得到明显提升。与未使用雾化相比,在6.0 V条件下雾化20 min的电池的电流输出增加20%。雾化技术还可以重新激活搁置的电池;雾化协同送风使电池性能几乎重新恢复到出厂前的状态,同时促进了电池高电流输出时的稳定性。电池极限输出功率比出厂前高出约24.9%。Polymer electrolyte membrane fuel cell(PEFC)is a green energy utilization technology,and the internal water-heat balance is very important for PEFC performance.Through atomization cooling experiment,non-continuous atomization experiment and atomization activation battery experiment,the effect of atomization on the performance and lifetime of polymer electrolyte membrane fuel cell was explored.The results show that compared with no atomization,the average temperature of PEFC can be reduced by 10℃under 100 mL/h atomization.After non-persistent atomization,the PEFC performance can be obviously improved in the whole working voltage range.PEFC performance at 6.0 V for 20 min of atomization is 20%higher than the current voltage without atomization.Atomization technology can also be used to reactivate the PEFC.The atomization combined with air supply makes the cell almost recover to the pre-factory performance,while also promoting the stability at high current output.The PEFC's ultimate output power is about 24.9%higher than before it is manufactured.
