Lecture

Electrochemical Thermodynamics: Efficiency and Potentials

Description

This lecture delves into electrochemical thermodynamics, focusing on the connection between free energy and electrochemical parameters. Topics covered include the Nernst equation for non-standard conditions, thermodynamic efficiency in fuel cells, Carnot efficiency in heat engines, and the concept of potential in electrochemistry. The lecture also explores the thermoneutral cell potential, conversion and electrochemical efficiencies, and the relationship between equilibrium constant, free energy, and cell potential. Examples are provided to illustrate the application of these concepts in solid electrolyte fuel cells and non-standard conditions.
