Ba kamar roka ba, ƙwayoyin man fetur na hydrogen suna samar da makamashin motsa jiki ta hanyar tashin hankali na hydrogen da konewar iskar oxygen, kuma suna sakin makamashin Gibbs kyauta a cikin hydrogen ta hanyar na'urorin motsa jiki. Gibbs makamashi kyauta shine makamashin lantarki wanda ya haɗa da entropy da sauran ka'idoji. Ka'idar aikin tantanin man fetur na hydrogen shine cewa hydrogen yana bazuwa zuwa ions hydrogen (watau protons) da kuma electrons ta hanyar mai kara kuzari (Platinum) a cikin ingantaccen lantarki na tantanin halitta. Ions na hydrogen suna wucewa ta cikin membrane na musayar proton zuwa mummunan electrode kuma oxygen suna amsawa don zama ruwa da zafi, kuma daidaitattun electrons suna gudana daga ingantacciyar wutar lantarki zuwa mummunan lantarki ta hanyar waje don samar da makamashin lantarki.
A cikinman fetur tari, Ana aiwatar da martani na hydrogen da oxygen, kuma akwai cajin canja wuri a cikin tsari, yana haifar da halin yanzu. A lokaci guda, hydrogen yana amsawa tare da oxygen don samar da ruwa.
A matsayin tafkin amsa sinadarai, mabuɗin fasahar ginshiƙi na tarin ƙwayoyin man fetur shine "proton musayar membrane". Bangarorin biyu na fim ɗin suna kusa da Layer na ƙara kuzari don lalata hydrogen zuwa ions da aka caji.
