，而且可逆。該基本原理已於2013年申請專利。

可能的細菌儲氫模型：白bai天tian
，在zai太tai陽yang能neng係xi統tong的de幫bang助zhu下xia發fa電dian
，然ran後hou電dian解jie水shui製zhi氫qing。通tong過guo這zhe種zhong方fang式shi產chan生sheng的de氫qing在zai細xi菌jun的de作zuo用yong下xia與yu二er氧yang化hua碳tan結jie合he
，從cong而er形xing成cheng甲jia酸suan。該gai反fan應ying是shi自zi由you可ke逆ni的de，反fan應ying的de方fang向xiang僅jin受shou起qi始shi物wu質zhi和he終zhong產chan物wu質zhi濃nong度du的de控kong製zhi。夜ye間jian
，生sheng物wu反fan應ying器qi中zhong氫qing濃nong度du下xia降jiang，在zai細xi菌jun的de作zuo用yong下xia氫qing開kai始shi從cong甲jia酸suan中zhong被bei釋shi放fang出chu來lai。釋shi放fang出chu來lai的de氫qing可ke以yi用yong作zuo能neng源yuan。 

該(gai)技(ji)術(shu)中(zhong)二(er)氧(yang)化(hua)碳(tan)和(he)甲(jia)酸(suan)之(zhi)間(jian)可(ke)逆(ni)的(de)轉(zhuan)換(huan)速(su)率(lv)是(shi)在(zai)有(you)相(xiang)關(guan)報(bao)道(dao)以(yi)來(lai)最(zui)高(gao)的(de)，比(bi)其(qi)他(ta)生(sheng)物(wu)或(huo)化(hua)學(xue)催(cui)化(hua)劑(ji)的(de)催(cui)化(hua)速(su)率(lv)高(gao)很(hen)多(duo)倍(bei)。與(yu)化(hua)學(xue)催(cui)化(hua)劑(ji)不(bu)同(tong)，這(zhe)種(zhong)細(xi)菌(jun)不(bu)需(xu)要(yao)稀(xi)有(you)金(jin)屬(shu)或(huo)高(gao)溫(wen)高(gao)壓(ya)等(deng)極(ji)端(duan)條(tiao)件(jian)來(lai)進(jin)行(xing)反(fan)應(ying)
，而(er)是(shi)在(zai)30℃且常壓下進行反應。該小組在上述細菌的幫助下開發了一種用於氫存儲的生物電池。
