Advanced materials are needed to achieve strong storage tanks with the necessary capacity. Fuel Cell Components Fuel Cells Fuel cells generally convert hydrogen and oxygen into water, producing electricity. Because they produce only water vapor as emissions, fuel cells are ideal power sources for transportation, providing power for an electric drive motor. See the Fuel Cell section of the EREN Hydrogen page for information about fuel cell technologies. Fuel Reformers Fuel cells generally convert hydrogen and oxygen into water, producing electricity.
Catalytic converters treat exhaust gases to remove nitrous oxides.
Cost-effective, highly sensitive sensors that are quick to respond are needed. Particulate Filters and Traps Filters and ceramic traps may help remove particulates from diesel engine emissions.
