Electrochemical Behavior of Metal Bipolar Plate Used to DMAFC,Yang Chun (Hubei University),Contents,Three-Electrode Cell,Parameter Background,Pt，Hg，Hg2Cl2(s) | Cl-(c),E = 0.2415 V,Parameters Setting,Electrochemical Workstation（CHI600B）,The Taguchi method Introduction,Advantage of The Taguchi method 1、Reducing the variation in a process 2、Produce high quality product at low cost to the manufacturer 3、How different parameters affect the mean and variance of a process 4、Performance characteristic defines how well the process is functioning,orthogonal Experimental Design,The collection of the necessary data determine factors most affect product quality with a minimum amount of experimentation, thus saving time and resources. The Taguchi method is best used when there is an inter- mediate number of variables (3 to 50), few interactions between variables, and when only a few variables contribute significantly.,Method Design of Experiments,Orthogonal Experimental Design,Linear Sweep Voltammetry (LSV),Experiments 1-3 (LSV),Experiments 4-6 (LSV),Experiments 7-9 (LSV),Parallel Plot (LSV),Amperometric I-t Curve,Experiments 1-3 (I-t curve),Experiments 4-6 (I-t curve),Experiments 7-9 (I-t curve),Parallel Plot (I-t curve),Conclusion,Plan,1、Evaluation the corrosion resistance performance and service life of SS316L in acid environment 2、Simulated solution of 70 0.5M H2SO4+5ppm F 3、The open circuit potential - time curves, the potentio- dynamic curv
