Fuel cell imhando yemagetsi ekugadzira magetsi, inoshandura simba remakemikari muhuturu kuita simba remagetsi nekuita redox kweokisijeni kana mamwe oxidants. Mafuta anonyanya kuzivikanwa ndeye hydrogen, iyo inogona kunzwisiswa seye reverse reaction yemvura electrolysis kune hydrogen uye oksijeni.
Kusiyana neroketi, hydrogen mafuta sero haiburitse kinetic simba kuburikidza nechisimba chekuita kwehydrogen uye oxygen kupisa, asi inoburitsa Gibbs yemahara simba muhydrogen kuburikidza necatalytic mudziyo. Nheyo yekushanda kwayo ndeyokuti haidrojeni yakasvibiswa kuita maerekitironi uye hydrogen ions (protons) kuburikidza nekatani (kazhinji platinum) mu electrode yakanaka yehuni sero. MaProton anosvika kune negative electrode kuburikidza neproton exchange membrane uye anoita neokisijeni kugadzira mvura nekudziya. Maerekitironi anofambirana anoyerera kubva kune yakanaka electrode kuenda kune yakaipa electrode kuburikidza nekunze redunhu kuti abudise simba remagetsi. Iyo haina bhodhoro rekushanda kwemafuta anosvika makumi mana muzana einjini yemafuta, uye kushanda kwehydrogen mafuta cell kunogona kusvika nyore kupfuura 60%.
Kare semakore mashoma apfuura, simba rehydrogen rave richizivikanwa se "yekupedzisira fomu" yemagetsi matsva emagetsi nekuda kwekunakirwa kwayo kwe zero kusvibiswa, simba rinogona kudzokororwa, kukurumidza hydrogenation, yakazara siyana uye zvichingodaro. Nekudaro, iyo tekinoroji dzidziso yehydrogen mafuta sero yakakwana, asi kufambira mberi kwemaindasitiri kwakadzokera kumashure. Imwe yematambudziko makuru ekusimudzirwa kwayo kudzora mutengo. Izvi zvinosanganisira kwete chete mari yemotokari pachayo, asiwo mari yekugadzirwa kwehydrogen uye kuchengetedza.
Kuvandudzwa kwehydrogen mafuta emotokari kunoenderana nekuvakwa kwehydrogen mafuta masisitimu akadai sekugadzirwa kwehydrogen, kuchengetedzwa kwehydrogen, kufambiswa kwehydrogen uye hydrogenation. Kusiyana nematramu akachena, anogona kubhadhariswa zvishoma nezvishoma kumba kana mukambani, mota dzehydrogen dzinogona kubhadhariswa chete pachiteshi chehydrogenation, saka kudiwa kwechiteshi chekuchaja kunonyanya kukurumidza. Pasina yakakwana hydrogenation network, kusimudzira indasitiri yemotokari yehydrogen hazvigoneke.
