Polymer Electrolyte–Based Electrochemical Devices: Advances, provides a complete overview of the theoretical and applied aspects of energy-related polymer electrolyte-based technologies. The book presents detailed thermodynamic and other basic requirements for smart materials like fuel cells, electrolyzers, batteries, sensors and devices for the abatement of pollutants. Delving into the physical-chemical, electrochemical, and mechanical properties of smart materials, it covers fundamental analysis and modeling to optimize the application of smart materials in terms of conductivity, chemical stability and kinetic properties. Detailed protocols for operation are suggested and discussed, including component development to optimize functionality, cost and upscaling. By exploring examples of actual prototypes based on recent research findings, analyzing requirements and cost estimate for large-scale production and implementation, as well as for their integration into existing systems, the environmental impact of multiple electrochemical applications is also examined.
