Prepackaged mmo anode

Description

MMO anodes are composed of a titanium substrate coated with a mixed-metal-oxide catalyst. Because the titanium substrate is naturally passivated by an oxidizing film, the anode remains Dimension stable over time. Direct current transfer is accomplished through the mixed-metal-oxide catalyst, which is highly conductive, and fully oxidized so that the higher current outputs are possible.
