Acid-Doped Polybenzimidazole as a Membrane for Electrochemical Hydrogen Sensors
A proton polymer electrolyte based on polybenzimidazole has been proposed for hydrogen sensors operating at room temperature in air. The potential response in inert gas containing hydrogen conforms to the Nernst equation. In air, the electromotive force is a mixed potential resulting from the combined effects of hydrogen oxidation and oxygen reduction. Regardless of the … Read more
