Electrocatalytic hydrogen oxidation by an enzyme at high carbon monoxide or oxygen levels.

Abstract:

Use of hydrogen in fuel cells requires catalysts that are tolerant to oxygen and are able to function in the presence of poisons such as carbon monoxide. Hydrogen-cycling catalysts are widespread in the bacterial world in the form of hydrogenases, enzymes with unusual active sites composed of iron, or nickel and iron, that are buried within the protein. We have established that the membrane-bound hydrogenase from the beta-proteobacterium Ralstonia eutropha H16, when adsorbed at a graphite ele...
