    The platinum nanoframes have 22 times the sepcific catalytic activity of standard electrodes © Science/AAASUS scientists have created an exceptional fuel cell catalyst that contains far less platinum – conventional catalysts need 36 times more platinum to hit the same levels of activity. The manufacturing process, which was discovered by accident, uses simple techniques that the researchers believe can be easily scaled-up. The work could help to make fuel cells economically viable for applications such as cars as the precious metal makes up much of the cost of the cell.Fuel cells react hydrogen with oxygen to produce water, using the...
