Stanford Scientists Develop Low-Cost Water Splitter

Hydrogen gas is used to power zero-emissions fuel cell vehicles, but most hydrogen is made from fossil fuels that contribute to global warming. Stanford University Professor Hongjie Dai has developed an emissions-free electrolytic device that splits water into hydrogen and oxygen at room temperature. The device runs on an ordinary AAA battery using electrodes made of inexpensive nickel and iron.
