Produced by College of the Desert and SunLine Transit Agency with funding from the U.S. Federal Transit Administration, this course manual features technical information on the use of hydrogen as a transportation fuel. It covers hydrogen properties, use, and safety as well as fuel cell technologies, systems, engine design, safety, and maintenance. It also presents the different types of fuel cells and hybrid electric vehicles.

Based on Phase 3 and 4 Ballard fuel cell buses, the system descriptions and maintenance procedures focus on proton-exchange-membrane (PEM) fuel cells for heavy-duty transit applications. The PEM fuel cell engine is the most promising for automotive applications; its transit application is the most advanced.
