将双氧水加入到阳极燃料甲醇溶液中来研究其对DMFC性能的影响。双氧水作为阳极助氧化剂将甲醇催化氧化产生的中间体CO氧化成气体CO2排出，从而减少中间体在催化层表面的吸附，增强催化剂的催化性能，从而提高电池的输出性能。通过探讨不同双氧水浓度和不同温度情况下，甲醇催化氧化的氧化峰电流密度及自呼吸式燃料电池的极限功率密度，阻抗等性能来分析双氧水在其中的作用。结果表明低浓度的双氧水确实能提高DMFC的输出性能，并且在双氧水的浓度为0.05 mol/L，温度为55℃时DMFC性能最佳。

The effect of hydrogen on the performance of direct methanol fuel cell(DMFC) with hydrogen added in methanol solution was studied. The CO produced by methanol oxidation was oxidized to CO2 with the help of hydrogen as anode pro-oxidant, thus the intermediate absorption on the surface of catalytic layer can be reduced and the catalytic properties can be improved to improve the output performance of DMFC. The oxidation peak current density of methanol oxidation and the maximum power density and impedance of self-breathing type fuel cellwere researched at different concentrations of hydrogen and different temperatures to analyze the function of hydrogen. The results show that the output performance of DMFC is improved by the low concentration of hydrogen, and the optimal performance can be obtained at the hydrogen concentration of 0.05 mol/L and 55℃.
