Water has Hydrogen |
Hydrogen is the simplest element. An atom of hydrogen
consists of only one proton and one electron. It's also the most plentiful
element in the universe. Despite its simplicity and abundance, hydrogen doesn't
occur naturally as a gas on the Earth - it's always combined with other
elements. Water, for example, is a combination of hydrogen and oxygen (H2O).
Hydrogen is also found in many organic compounds, notably
thehydrocarbons that make up many of our fuels, such as gasoline, natural gas,
methanol, and propane.
Hydrogen fuel cell |
A fuel cell combines hydrogen and oxygen to produce
electricity, heat, and water. Fuel cells are often compared to batteries. Both
convert the energy produced by a chemical reaction into usable electric power.
However, the fuel cell will produce electricity as long as fuel (hydrogen) is
supplied, never losing its charge.
Fuel cells are a promising technology for use as a source of
heat and electricity for buildings, and as an electrical power source for
electric motors propelling vehicles. Fuel cells operate best on pure hydrogen.
