A protective shield for sensitive enzymes in biofuel cells

Researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is based on oxygen-consuming enzymes that draw their energy from sugar.
