Abstract
A titanium sheet ( ) serving as an anode-forming member is fixed on a tube plate ( ) of a heat exchanger ( ) via a insulting sheet ( ) and an insulating adhesive ( ). The sheet ( ) is coated with a film ( ) of an electrochemically active, stable electrical catalyst. A dc power unit ( ) has a positive electrode ( ) electrically connected to the sheet ( ), and a negative electrode ( ) electrically connected to the tubes ( ). The inner surfaces of the tubes ( ) are used as a cathode for electrolysis for oxygen generation. An automatic potential controller ( ) adjusts potential difference between the electrodes ( ) such that oxygen is generated in seawater while generation of chlorine in seawater is suppressed. An external dc power unit ( ) and a cathodic protection electrode ( ) supply a cathodic protection current to the tubes ( ).
