    The new Artificial Leaf JCAP system has 3 main components: 2 electrodes–one photoanode and one photocathode, and a membrane. The photoanode uses sunlight to oxidize water molecules, generating protons and electrons as well as oxygen gas. The photocathode recombines the protons and electrons to form H2...
