Contamination of fuel-cell membranes with metal ions, resulting from the use of ferrous alloys, leads to corrosion and ultimately failure of the device. By using a combination of X-ray spectroscopy techniques, the corrosion processes of Ni and Fe electrodes in contact with a hydrated Nafion film are investigated. The results show diffusion of corrosion products within the film only in the case of the Fe electrodes, whereas Ni electrodes appear corrosion resistant.

Abstract
Contamination of fuel-cell membranes with metal ions, resulting from the use of ferrous alloys, leads to corrosion and ultimately failure of the device. By using a combination of X-ray spectroscopy techniques, the corrosion processes of Ni and Fe electrodes in contact with a hydrated Nafion film are investigated. The results show diffusion of corrosion products within the film only in the case of the Fe electrodes, whereas Ni electrodes appear corrosion resistant.File in questo prodotto:
