Techniques for Fuel Cell Characterisation
Module Title - Techniques for Fuel Cell Characterisation
Number of credits – 10
The module aims to develop an understanding of the measurements techniques used in development and study of fuel cells. The course is sub-divided into two sections:
- Electrochemical Techniques
- Material Characterisation Techniques
The first section introduces the electrochemical techniques to understand catalyst performance, durability and electrochemically active surface (ECSA) area. These will include Tafel plot, cyclic voltammetry, chronoamperometry, electrochemical impedance spectroscopy. Working principle and types of fuel cells; concept of power, relation between current and voltage and I-V curve; concepts like reversible and irreversible reaction and two and three electrode systems, Randles-Sevcik equation, overpotential and other electrochemistry concepts relevant to fuel cells are also included.
Material characterisation discusses the principles and importance of techniques available (XRD, TGS, SEM, TEM, IR, NMR) to study composition and surface characteristics of various components (catalysts, supports, MEA, GDL) of fuel cells.
