How the New Alloy Method Works

Caption

Nanoalloys of platinum (grey) and yttrium (blue) are created using sputtering in a vacuum chamber. This is done by directing plasma (purple) at a piece of platinum with small attached pieces of yttrium. The nanometre-thin alloy films effectively transform oxygen (red) and protons (white) into water. It is this reaction that causes the fuel cell to generate electricity.
