Proton Exchange Membranes Fuel Cells: Thermodynamics, Electrochemistry, Component Design and Applications delivers a rigorous integration of thermodynamic and electrochemical principles underpinning Proton Exchange Membrane Fuel Cells (PEMFCs), Direct Methanol Fuel Cells (DMFCs), and PEM electrolyzers. The reference addresses a critical pedagogical gap by uniting foundational irreversible thermodynamics, electrokinetics, and transport theory with practical materials science for real-world device design. It is intended for graduate-level students, researchers, and engineers who require quantitative frameworks to predict fuel-cell behavior, design high-conductivity ion-exchange membranes, and analyze coupled heat, mass, and charge transport in operational systems. The book is structured in two parts spanning fourteen chapters. Part I develops the scientific foundations-thermodynamics, electrochemical kinetics, transport phenomena, membrane thermodynamics, and Nernst-Planck-based formulations of ionic motion and irreversible processes. Part II transitions to applied technologies, including membrane synthesis and characterization, nanocatalyst design with rotating disk and rotating ring-disk electrode diagnostics, membrane-electrode assembly (MEA) fabrication, bipolar-plate flow-field simulation, single-cell testing, PEM electrolyzer performance and hydrogen storage, and emerging microbial and plant-based fuel cell systems. This reference highlights the value of integrating theoretical derivations with experimental methodologies and simulation case studies. Readers learn to select and characterize ion-exchange membranes, rationalize catalyst composition and loading for MEAs, and optimize bipolar-plate geometries through finite-element modeling.The book provides detailed experimental methods-electrochemical impedance spectroscopy (EIS), conductivity and permeability measurements, scanning electron microscopy (SEM), RDE/RRDE diagnostics-and offers durability-assessment frameworks that bridge academic training and industrial prototyping. By combining fundamentals with applied design tools, it supports the global energy transition toward efficient, low-carbon hydrogen technologies and serves as both a graduate-level textbook and a practical reference for laboratory instruction and R&D teams worldwide.Equip readers with first-principles thermodynamics and electrochemistry to design, size, and evaluate proton exchange membrane (PEM) fuel cells and PEM electrolyzersProvide step-by-step synthesis and rigorous characterization of ion-exchange membranes and ORR/OER nanocatalysts, directly tied to measurable membrane-electrode assembly (MEA) performanceUse simulation-based methods (including FEM) to optimize bipolar-plate flow channels and predict single-cell polarization and losses before prototypingDeliver practical MEA assembly, activation, testing, and durability-assessment protocols for both PEMFCs and PEM electrolyzers

Global warming switches our reliance from fossil fuels to green, sustainable renewable energy sources. Because of its promising nature, high-efficiency nano-electrocatalysts have sparked interest in renewable energy. Hydrogen fuel cell/polymer electrolyte membrane (PEM) vehicles are the most environmentally conscious electromobility vehicles, with a high energy density and quick refuelling technology, prompting the auto industry to launch a variety of PEM fuel cell vehicles around the world. Oxygen reduction reaction (ORR) primary research interests include fuel cells and metal-air batteries. The sluggish kinetic reaction of ORR, which is responsible for the rate-limiting reaction at the PEM fuel cell cathodic system, further decreases energy efficiency. Optimising ORR for market expansion with cost-effective and efficient nano-electrocatalysts, on the other hand, remains a challenge.The book covers fundamental ORR reaction kinetics theories, tools, and techniques. It also explains the nano electrocatalysts for ORR made of noble, non-noble, and nanocarbon materials. Finally, the book explores the applications of PEM fuel cells and metal-air batteries.
