Ministry of Education has established a number of new energy related majors in recent years to meet the the national energy strategy and the needs of the new energy industry.Electrochemistry plays an increasingly important role in the field of new energy,so fundamentals of Electrochemistry is the teaching important contents of this major.However,it has been found that it is very difficult for students to understand some concepts solely through classroom teaching.Taking the hydrogen production by water electrolysis process as a model,an electrochemical open experiment was designed and conducted,allowing undergraduate students to complete the preparation,phase composition,and microstructure analysis of NiCoP nanocatalysts,and test the polarization curve of the catalyst in hydrogen produce process to study its electrocatalytic performance in laboratory.By analyzing the characteristic of the polarization curve under different testing conditions,the understanding of the important electrochemical knowledge-polarization effect was deepened,students'scientific research interest was cultivated,their practical ability and innovative thinking were enhanced.
