英國科學家研發出尿液燃料電池

據http://www.supergenfuelcells.co.uk/網站報道，英國科學家研發出尿液燃料電池，這種尿液燃料電池可以使用人或動物尿液發電
，同時還可以回收其中的必需營養元素。

該研究團隊由來自於布裏斯托爾機器人實驗室的Ioannis Ieropolous和John Greenmangongtongzhuchi，jizhongyanfaweishengwuranliaodianchi

，因此，由成千上萬個細胞構成的燃料電池堆棧可以使用來自家庭、農場或公廁的尿液製造大量電能。

尿液在廢水處理過程中特別難處理，因為尿液中不但包含有機化合物，還含有較高水平的氮、linhejiayingyangyuansu，wushuichulichangxuyaohuafeidaliangdeshijianhenengliangcainengjiangzhexieyuansucongfeishuizhongquchu。ruguofeishuizhongzhexieyuansubujingchulijipaifanghaihuizaochenghouxuhuanjingwuran，yuguolianghuafeicongnongtianturangzhonglinrongchulaijinrushuitizaochengdewuranleixingyiyang，zhexieyingyangyuansuhuicijishuitizhongdezaoleidaliangfanzhizusaiheliushuidao
