Polymer Electrolyte Membrane ‎(‎PEM‎)‎ fuel cells hold great promise as a potential alternative to conventional fossil‎-fuel‎-powered energy sources‎.‎ However‎,‎ they produce waste heat‎,‎ and the water used in their system must be carefully controlled and monitored‎.‎ This monograph in Momentum Press‎'‎ ‎'‎Sustainable Energy Series‎'‎ offers the most up‎-to‎-date research on advanced methods for managing both waste heat and monitoring water flows and water concentration in PEM fuel cells‎.‎ The most workable solutions to these problems and the challenges that still lie ahead are emphasized‎.‎ The reader will find‎:‎ a review of multi‎-component mass transport phenomena‎,‎ particularly as they apply to gas flow and hydrogen and air flow‎;‎ coverage of multi‎-phase flow and heat transfer characteristics of PEM fuel cells‎;‎ and unique coverage of solid water phase behavior of PEM fuel cells and subfreezing temperature operation‎.‎
