Abstract
Description
本実施形態に係る微生物燃料電池システム100は、図1及び図2に示すように、単一槽の給排室1を備える。給排室1は、処理液である電解液4の供給口2と、電解液4の排出口3とを有し、電解液4の供給及び排出を適宜行うことができる。供給口2及び排出口3の位置は図1の場合に限られず、電解液4の供給及び排出を行うことが出来れば、任意の場所でよい。本実施形態においては、給排室1が供給口2及び排出口3を有する場合について示したが、給排室1が供給口2及び排出口3を有さない場合には、給排室1に直接電解液4の供給、排出を行ってもよい。また、供給口2及び排出口3として共通の給排出口を一つ設けてもよい。
本実施形態に係る正極5は、多孔性の導電体によって形成される。具体的には、カーボンペーパー、カーボンフェルト、カーボンクロス、または活性炭シートなどの炭素材料や、アルミニウム、銅、ステンレス鋼、ニッケル、またはチタンなどの金属メッシュなどが挙げられる。正極5は多孔質や織布状の材料によって形成されることで、多孔性を有してもよい。また、正極5は全体が多孔性を有していてもよいし、一部が多孔性であってもよい。
[硝化反応]
[式1]2NH4 ++3O2→2NO2 −+2H2O+4H+
[式2]2NO2 −+O2→2NO3 −
[脱窒反応]
[式3]NO3 −+2H++2e−→NO2 −+H2O
[式4]2NO2 −+6H++6e−→N2+2H2O+2OH−
式1及び式2のように、本実施形態に係る微生物燃料電池システム100の正極5では、気相に露出した一方の面51から酸素が供給され、硝化菌の触媒作用により、硝化反応が起きる。電解液4が保持する脱窒菌は、正極5の近傍に集まり、触媒として作用する。
本実施形態における負極6は、後述する微生物を担持し、さらに微生物の触媒作用により、電解液4中の有機物から水素イオン及び電子を生成する作用を有する。そのため、本実施形態の負極6は、このような作用を生じさせる構成ならば特に限定されない。
[式5]C6H12O6+6H2O→6CO2+24H++24e−
式5のように、本実施形態に係る微生物燃料電池システム100の負極6では、有機物が、負極6に担持された電流生成菌による触媒作用によって分解され、二酸化炭素、水素イオン及び電子を生成する。式5の反応により、負極6においては電解液4中の有機物処理を行うことが出来る。
本実施形態の微生物燃料電池システム100は、負極6と正極5との間に配置され、少なくとも水素イオンを透過するイオン透過膜7をさらに備える。そして、図1に示すように、負極6は、イオン透過膜7を介して正極5と隔てられている。イオン透過膜7は、負極6で生成した水素イオンを透過し、正極5側へ移動させる機能を有している。
次に、第二実施形態に係る微生物燃料電池システムについて、図面に基づき詳細に説明する。なお、第一実施形態と同一構成には同一符号を付し、重複する説明は省略する。
