Proton exchange membrane fuel cell (PEMFC) operation involves multiphase mass, charge, and heat transport, complex electrochemical reactions, and physical processes that occur at multiple spatial and time scales, e.g., from double-layer effects occurring in milliseconds to catalyst degradation...
Devices employing the concept of kinetic energy storage date back to ancient times. Pottery wheels and spinning wheels are early examples of systems employing kinetic energy storage in a rotating mass. With the advent of modern machinery, flywheels became commonplace as steam engines and internal...
