A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. In order to produce energy, fuel cells use oxygen and hydrogen. Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. It’s also the most plentiful known element in the universe. Despite its simplicity and abundance, hydrogen doesn’t occur naturally as a gas on the Earth. However scientists have discovered how oxygen stops green algae from producing hydrogen. The findings could help those working towards “solar H2-farms” in which microorganisms produce hydrogen fuel from sunlight and water.
