Fuel cells, are expensive, though, and their price is due to platinum, which is a rare metal.

In the search for finding better materials for making fuel cells, researchers have already found alternatives to the expensive platinum a long time ago, but they were not as efficient. One of this substitute materials is palladium - far cheaper and much more abundant, but that didn't have enough surface area to make the fuel cell catalysis efficient.
