“…Most cells are equipped with coated titanium anodes [181], and only some 5 -10 % of all chlorate cells still use graphite anodes. Older cells have also been operated with anodes of magnetite (Fe 3 O 4 ) [182], [183], platinum [184], graphite [185][186][187][188], or lead dioxide [189], [190]; reviews on these older anodes can be found in [39] and [191][192][193]. The following survey is restricted to modern cells with coated titanium anodes.…”
