Phosphoric Acid Fuel Cell History Bus running on an H Power phosphoric acid fuel cell, 1996.   Image #490,001,001 from the ETV Collection, U.S. Department of Energy Original Department of Energy caption: "Bus powered by phosphoric acid fuel cell / battery propulsion system. "This bus was developed by H. Power Corp. of Belleville, NJ for the Department of Energy as part of the Fuel Cell Bus Project. Fuel cells produce electricity by combining hydrogen and oxygen atoms. Since they have no moving parts, they produce little or no noise. Except for ordinary water, they produce near zero emissions and can offer the same performance as conventional gasoline and diesel-fueled vehicles."
