The role of recombination catalysts in VRLA cells

The lead-acid battery, introduced around the mid-19th century, Palladium is the material of choice for the catalyst, although other noble metals can be used. The metal, in a finely divided form, is coated on the surface of a substrate such as carbon or ceramic in order to maximize its surface area. The catalyst (comprising the noble metal on its substrate) is then
