デンキウナギは敵から身を守るために600ボルトの電圧を作り出すことができる。デンキウナギの体の長さの約半分は発電できる細胞（電気細胞）でできており、1個の電気細胞は約140ミリボルトの電圧を作ることができる。たとえば、4500個の電気細胞が直列につながれば、630ボルトの電圧を作り出すことができる。デンキウナギの電気細胞はきれいに整列した状態で並んでおり、同じ方向に電気が流れている。デンキウナギの頭側がプラスだとすると尻尾側はマイナスという関係で、頭から尻尾側に電気が流れている。エサとなる小さい魚を発見したときは弱い電気で魚をしびれさせて食べる。
新しい電気の供給装置の開発に応用できる。電気細胞を利用して、体内に埋め込むタイプの医療要員プラントへの電力供給源になる技術の開発に応用できる。
