A step towards artificial photosynthesis

Fuel cells generate electrical energy through a chemical reaction of hydrogen and oxygen. To obtain clean energy, the splitting of water into its components of hydrogen and oxygen is critical. Researchers at Empa and the University of Basel study how sunlight can be used for this purpose. The scientific journal Chemical published their latest results. Artificial photosynthesis is one of the most promising approaches to create clean energy. With the aid of sunlight water is photo-electrochemicallyseparated into its components H? and O? and stored. When the chemical elements are later combined in a fuel cell, electrical energy can be created.
