Iodide salts stabilize biocatalysts for fuel cells

Contrary to theoretical predictions, oxygen inactivates biocatalysts for energy conversion within a short time, even under a protective film. A research team has found out why: Hydrogen peroxide forms on the protective film. The addition of iodide salts to the electrolyte can prevent this from happening and considerably extend the life of the catalysts. https://www.sciencedaily.com/releases/2020/02/200214134735.htm
