Fuel cells produce electricity from a number of domestic fuels, including hydrogen and renewables, and can provide power for virtually any application -- from cars and buses to commercial buildings. The Fuel Cell Technologies Office (FCTO) focuses on applied research, development, and innovation to advance hydrogen and fuel cells for transportation and diverse applications enabling energy security, resiliency, and a strong domestic economy in emerging technologies.
