面向氢能产业的Fe-N-C催化剂制备与燃料电池器件综合实验教学探索
Exploration of a Comprehensive Experimental Teaching for Fe-N-C Catalyst Preparation and Fuel Cell Device toward the Hydrogen Energy Industry
【摘要】 为解决物理化学电化学实验“重验证、轻探究”“理论与前沿脱节”的教学痛点,响应氢能产业对创新人才需求,本文基于“科研反哺教学”理念,设计Fe-N-C氧还原电催化剂制备及性能测试综合实验。通过气相沉积碳化方法合成Fe-N-C催化剂,在0.1 M HClO4溶液中,其半波电位达到0.78 V(vs. RHE),随后运用于质子交换膜燃料电池,其峰值功率密度为761 mW·cm-2。教学中,实验将电极过程动力学等理论融入全流程,通过基础操作-关联探究-自主优化训练,强化设备实操与理论应用能力,培养学生科研思维。该实验实现物理化学教学与前沿科研、产业需求的衔接,为课程改革提供可行范式,对提升学生综合素养具有重要意义。
【Abstract】 To address the teaching drawbacks of “prioritizing verification over inquiry” and “disconnect between theory and cutting-edge research” in physical chemistry electrochemical experiments, and respond to the demand for innovative talents in the hydrogen energy industry, this study designed a comprehensive experiment on the preparation and oxygen reduction reaction(ORR) performance testing of Fe-N-C electrocatalysts based on the concept of “scientific research feeding back into teaching”. Fe-N-C catalysts were synthesized via vapor deposition carbonization. In 0.1 M HClO4 electrolyte, the catalyst exhibited a half-wave potential(E1/2) of 0.78 V(vs. RHE). When applied in proton exchange membrane fuel cells(PEMFCs), it achieved a peak power density of 761 mW·cm-2. In teaching practice, the experiment integrates theories such as electrode process kinetics throughout the entire workflow. Through the training system of “basic operationcorrelative exploration-independent optimization”, it enhances students’ abilities in equipment operation and theoretical application, and cultivates their scientific research thinking. This experiment realizes the connection between physical chemistry teaching, cutting-edge scientific research and industrial needs, provides a feasible paradigm for curriculum reform, and is of great significance for improving students’ comprehensive literacy.
