This second edition reference provides full and updated coverage of fuel cell principles and applications as well as examples of the modeling and design of actual fuel cell systems. Larminie (Oxford Brookes U., UK) and Dicks (U. of Queensland, Australia) cover major fuel cell types, future technologies, direct methanol fuel cells, fuel cell operation and thermodynamics, fuel processing, and hydrogen storage and generation. System components such as compressors, turbines, regulators, inverters, grid inter-ties, electric motors, and hybrid fuel cell/battery systems also receive attention. The audience will be students and researchers in electrical, power, chemical, and automotive engineering. No prior knowledge of fuel cell chemistry is required.
