Abstract

La présente invention concerne un revêtement protecteur de courant appliqué sur le collecteur métallique d'une électrode. Le revêtement protecteur comprend un liant minéral vitreux ou partiellement et optionnellement un additif de conduction électronique. Ce revêtement est appliqué sous forme de solution ou dispersion sur le collecteur de l'électrode, et séché, de façon à couvrir et protéger au moins une partie de la surface du métal du collecteur afin d'éviter la formation de films isolants engendrés par les espèces actives provenant des autres composantes du générateur.
