Fuel Cells: Working Principles

This lecture covers the working principles of fuel cells, including the chemical reactions involved, electrode surfaces, materials, and structures, as well as the role of the electrolyte. It also discusses electrochemical thermodynamics, kinetics, and transport phenomena, with a focus on real electrochemical systems. Examples are provided to illustrate concepts such as thermodynamic efficiency and the effect of temperature on efficiency. The lecture concludes with a detailed explanation of cell potential in fuel cells.
