应用MFC技术成功地实现了醋酸和电的联产。在阳极表面形成醋酸细菌生物膜对提高乙酸产率、最大电流和功率密度具有重要意义。研究了利用等离子体射流对碳材料表面进行改性以提高醋酸细菌与碳表面亲和力的工艺。结果表明，二氧化碳和氩气混合气体的等离子体射流对提高亲和性能最有效。为构建填料床反应器式MFC装置进行了知识积累。除了使用阳极的碳材料的种类和来源外，集流器的设计对产生大电流也很重要。

The coproduction of acetic acid and electricity by applying MFC technology was successfully demonstrated. Formation of acetic acid bacteria biofilm on anode surface was important to increase acetic acid productivity, maximum current and power densities. A modification technology of carbon material surface to improve the affinity between acetic acid bacteria and carbon surface using plasma jet was investigated. It was shown that the exposure of plasma jet using mixture gas of carbon dioxide and argon was the most effective to improve the affinity. The accumulation of knowledge to construct packed bed reactor style MFC setup was carried out. In addition to the kind and from of carbon material using anode, the design of current collector was also important to generate large current.
