摘要
本文介绍了一个材料化学专业实验。该实验通过制备一种空心状的铂基合金催化剂,使学生了解直接甲醇燃料电池的工作原理,掌握砂芯抽滤装置和冷冻干燥机的使用方法。实践证明通过该实验的学习,学生不但巩固了理论课所学的燃料电池知识,而且提高了基本实验技能。
In this paper, a material chemistry experiment is introduced. By synthesizing a Pt-based nano-catalyst with hollow structure, the college students not only learn how a direct methanol fuel cell works, but also learn how to use freezer dryer and vacuum filtration device. It is shown that students not only consolidate the fuel cell knowledge which studied in theory course, but also improve their basic experimental skills.
