| 摘 要： | 针对向车载制氢机加水带入的金属离子导致制氢效率偏低的问题,在制氢测试系统实验台上研究加入含不同Zn2+、Fe3+和Cu2+质量浓度的溶液对制氢效率的影响.在电解电流为30 A,初始温度为19.7℃,压力恒为0.1 MPa条件下,电解2 L质量分数为30%的KOH溶液与其对应加入50 mL含不同金属离子质量浓度溶液做比较.试验结果表明：随着电解的进行,加入溶液所含的金属离子质量浓度越高,KOH溶液的电解电压越高,制氢速率越低,制氢效率越低.

| Abstract: | In view of the low efficiency of on-board hydrogen generator used in the vehicle with hydrogen-blended gasoline engine due to adding metal ions in water, effects of different concentration of Zn2+, Fe3+ and Cu2+ on performance of the on-board hydrogen generator with KOH liquor were tested on hydrogen generator testing bench in this paper. The experiment was carried out at the electrolytic current of 30 A, the initial temperature of 19. 7 ℃ and the pressure of 0. 1 MPa. The effect of adding 50 mL metal ions liquor to the 2 L KOH liquor which has a KOH mass fraction of 30% was investigated and compared with the pure KOH liquor electrolyzing. Results show that the electrolytic voltage is increased, and the hydrogen producing velocity and efficiency are reduced with the increase of metal ions concentration. |
