Fuel cells runs on the cleanest gas mixture in the world - AIR! Fuel cells may be capable of replacing the battery, because it generates its own
energy both cheaply and in an environmentally friendly way.

Fuel cell technology may contribute to more efficient and environmentally friendly energy use. In a fuel cell the fuel is converted directly to
electricity by oxidation with air in an electrochemical process. The fuel might be hydrogen, natural gas, other hydrocarbons or alcohols. Powered by
hydrogen the fuel cell produces only water in addition to electricity and heat. The efficiency of a fuel cell may be higher than traditional power
conversion utilizing combustion technologies. The low operation temperature and higher efficiency of the fuel cell may contribute to significant
reductions in local emissions of CO2, NOx, CO and VOC. With no moving parts the fuel cell of the future may provide advantages in terms of
maintenance, less noise and increased reliability. In a future energy scenario, where an increasing part of the energy stems from renewable sources,
the fuel cell is expected to play a key role in several areas of application.
