1つの例において、0.7cmの最小直径を伴う8cmの長さの、鋳造亜鉛陽極を、導電性セラミックの印加電流陽極管の内部でパックされる、ZnO/チキソトロピックのペーストに位置付けた。亜鉛ペーストを、カルボキシメチルセルロースナトリウムの増粘剤と共に、2M KOH及び20%ZnOを備えたLiOHで飽和させた溶液から作成した。亜鉛陽極と28mmチューブの内側との間の空間において、ペーストをパックした。イオンが多孔性の管壁を通過することができ、その結果、たとえ印加電流陽極の内部に位置つけられたとしても、亜鉛陽極は外部鋼鉄筋上に電流を通すことができることが、試験によって示された。続いて、亜鉛の充電は、印加電流陽極と犠牲陽極の間に外部電圧を適用することにより、印加電流の多孔性管状陽極を通るイオンの流れを逆にすることによって、達成され得る。約6-8ボルトの印加電圧は、ちょうど40,000クーロン未満の合計の充電/再充電を達成する内部亜鉛陽極に送達される、1.6Aまでの電流を、結果としてもたらした。驚くことに、亜鉛陽極は、元のものよりも、再充電後に行われた方が優れていた。亜鉛陽極の充電後、亜鉛陽極が鋼に再度接続された時、鋼へと通じる多孔性の管状の印加電流陽極により充電した亜鉛陽極の電流出力及び蓄積した充電出力は、本来の亜鉛陽極と比較して、増大した。性能におけるこの改善の正確な理由は知られていないが、充電後の陽極の電流出力は増大する。
原位置で陽極を充電/再充電する能力を実証するための組立体(49)を、図11に示されるように構築した。それは、非常にアルカリ性の(7モーラー OH-)ゲル(51)に部分的に浸された、亜鉛ワイヤー(50)から成る。原位置で形成される犠牲陽極のための銅線コネクタ(53)も、同じゲルに浸した。繊維織物(55)及びイオン導電性膜(56)の層によって、内面的及び外面的の両方で並べられる、穿孔したプラスチックチューブ(54)内にゲルが包含された。外部織物とチューブの間で、混合金属酸化物(MMO)でコーティングしたチタンメッシュ(57)が周辺に固定され、それは、片側に取り付けられるチタン接続ワイヤー(58)を備えた。全体の組立体を、LiOHが豊富なモルタル(59)で覆った。
