An anode configured for the cathodic protection of reinforced concrete structures and underground metallic structures against corrosion comprises a hollow, mixed-metal-oxide (MMO) coated form, the form having a wall with intentional gaps therethrough. A humectant is disposed in the hollow form, and a conduit between the hollow form and an ambient environment enables gasses produced by the form to escape to the environment while allowing the humectant to be periodically moistened with water or a high pH buffer solution. The form may be composed of titanium, tantalum, zirconium, niobium or alloys thereof, and the MMO coatings may be composed of titanium, tantalum, iridium, ruthenium, palladium, cobalt or mixtures thereof. The form may be a coiled wire or strip, a perforated tube, or other structure having gaps between the interior of the form and the surrounding concrete or soil.
