摘要/Abstract

摘要： 针对掺氢汽油机汽车使用的车载制氢机效率偏低问题，在制氢机性能实验台上研究加入添加剂对制氢机效率的影响。在电解电流为40 A，初始温度为23.7 ℃，初始压力为0.1 MPa条件下，对电解质量分数分别为20%、30%和40%的KOH溶液与其对应单位体积中含有0.3 g重铬酸钾KOH溶液的电解电压与制氢效率进行比较。实验结果表明：在质量分数分别为20%、30%和40% KOH溶液中加入重铬酸钾电解电压分别降低0.16 V、0.19 V和0.09 V，制氢效率分别提高2.14%、2.78%和1.46%，制氢效率比分别提高5.23%、6.71%和3.47%；在质量分数为30% KOH溶液中加入重铬酸钾效果最好，可以有效提高制氢效率。

Abstract: In view of the low efficiency of on-board hydrogen generator used in the vehicle with hydrogen-blended gasoline engine, the effect of additive on the performance of on-board hydrogen generator with different mass fractions of KOH liquor is tested on a hydrogen generator testing bench. The experiment is carried out under the conditions of electrolytic current of 40 A, initial temperature of 23.7 ℃ and initial pressure of 0.1 MPa. The mass fractions of KOH are kept at 20%, 30% and 40% in the KOH liquor. For each KOH mass fraction, the effect of addition of 0.3 g K₂Cr₂O₇ on the electrolytic voltage and hydrogen production efficiency is investigated. The experimental results indicate that, when 20%, 30% and 40% KOH liquors are added into K₂Cr₂O₇, respectively, the electrolytic voltages are reduced by 0.16 V, 0.19 V and 0.09 V, the hydrogen efficiencies are increased by 2.14%, 2.78% and 1.46%, respectively, and the hydrogen efficiency ratios are increased by 5.23%,6.71% and 3.47%. The hydrogen production efficiency is effectively increased by adding 30% KOH liquor into K₂Cr₂O₇.
