catalyst
A substance that accelerates a chemical change without actually entering into the chemical reaction. A catalyst usually consists of platinum powder very thinly coated onto carbon paper or cloth. The catalyst is rough and porous so that the maximum surface area of the platinum can be exposed to the hydrogen or oxygen. The platinum-coated side of the catalyst faces the membrane in a fuel cell.
