摘要
《普通高中化学课程标准(2017年版)》中将"制作简易的燃料电池"列为学生必做实验。针对实验现象不明显的问题,采用铅笔芯做电极,用浸有Na2SO4溶液的海绵代替传统电解液。改进后氢氧燃料电池电流、电压大而且稳定,二极管发光时间长。
"Making Easy Fuel Cells" was listed as a compulsory experiment in the General High School Chemistry Curriculum Standards(2017 edition). Because the experimental phenomena were not obvious, this paper used the pencil lead as electrode and used the sponge immersed in sodium sulfate solution to replace the traditional electrolyte. The improved hydrogen-oxygen fuel cell had high current and stable voltage, and long diode luminescence time.
