摘　　要：提出了一种结合超声喷雾技术的新型高性能DMFC电池结构,并测试电池在不同实验条件下的极化曲线并分析实验数据。实验测试结果表明:在4 mol/L浓度下,与液体供给相比,超声喷雾将放电极限功率提高了66.7%;通过实验数据对比得出电池工作的最佳供给浓度、最优雾化速率以及电池的最佳放置方式,为直接甲醇燃料电池结构设计的优化提供了指导。A kind of new high-performance DMFC structure combined with ultrasonic spray technology was proposed,the polarization curves of DMFC under different experimental conditions were tested,and the experimental data were analyzed.The experimental test results show that:compared to the liquid supply,the ultrasonic spray increases the discharge limit power by 66.7%at the concentration of 4 mol/L methanol solution;through the comparison of experimental data,the optimal supply concentration,the optimal atomization rate and the optimal placement mode of the battery are obtained,which provides guidance for the optimization of the structural design of the direct methanol fuel cell.
