These have an enzyme, called hydrogenase, and use it to metabolize hydrogen.

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.
