ABSTRACT:
A method and apparatus for reducing corrosion on the interior and exterior of a fuel storage tank. A galvanic anode assembly is placed within the interior of or exterior to the fuel storage tank and is surrounded by a layer of hydrophilic gel. The hydrophilic gel absorbs water in the fuel storage tank, thus removing it from contact with the tank. The hydrophilic gel also absorbs metal ions produced as the anode is consumed. The hydrophilic gel is maintained around the anode assembly by a porous container. The anode, hydrophilic gel, and porous container are maintained within a flexible container that allows water and fluid contained within the fuel storage tank to contact the hydrophilic gel. In one embodiment, the hydrophilic gel includes a polyacrylamide material.
