Researchers from Rice University have discovered an efficient, robust way of drawing hydrogen and oxygen from water.
The researchers have developed a new catalyst of a cobalt-based thin film, which pumps out hydrogen and oxygen to feed fuel cells.
This from Rice University:
The inexpensive, highly porous material invented by the Rice lab of chemist James Tour may have advantages as a catalyst for the production of hydrogen via water electrolysis. A single film far thinner than a hair can be used as both the anode and cathode in an electrolysis device.
