摘要
为了研究葡萄糖循环电解制氢性能,在液体催化燃料电池的基础上,搭建了葡萄糖电解制氢系统,对比研究了加热反应时长及反应次数对系统电解制氢性能的影响。结果表明:阳极电解液在120℃下加热24h后,电解制氢系统在常温及1V恒电压下的初始电流密度可达232mA/cm^2,且首次电解制氢的制氢量达到173mL。当阳极电解液在相同温度下加热不同时长时,随着加热反应时长缩短,葡萄糖的制氢效果逐渐变差;随着阳极电解液循环加热反应次数增加,虽然系统的制氢量逐渐减小,但分解后的葡萄糖仍有一定的制氢效果,验证了葡萄糖循环电解制氢的可行性。
In order to study the hydrogen production performance from glucose with cyclic reaction electrolysis,aglucose electrolysis hydrogen production system on the basis of liquid-catalyst fuel cell was set up.The effect of heating duration and reaction times on the hydrogen production performance was comparatively studied.The results shown that after the anolyte was heated under 120℃for 24 h,the initial current density and the amount of hydrogen production were 232 mA/cm^2 and 173 mL respectively with the constant voltage(1 V).Besides,the hydrogen production performance will be worse if the heating duration decreased.The degradation product of glucose also can be the material to produce hydrogen,which verified the feasibility of hydrogen production from glucose with cyclic reaction-electrolysis.
