An anode assembly having high electrical and heat conductivity and corrosion resistance, comprising a copper member consisting of a substantially horizontal copper anode support plate, copper bus bars connected to said horizontal anode support plate and extending substantially vertically upward therefrom through the cover of an electrolytic cell and sheet titanium bar members extending into slots in said horizontal copper anode support plate and connected by pressure contact to said horizontal copper anode support plate to provide electrical conduction between said horizontal copper anode support plate and said sheet titanium bar members and a corrosion resistant plastic covering extending over said copper member and over the exposed joint between the copper member and said sheet titanium bar members, leaving portions of the titanium bar members extending therefrom, and platinum coated titanium anode plates removably attached to the uncovered parts of said titanium bar members.
