Sero remafuta imhando yemudziyo wekugadzira simba, unoshandura simba remakemikari mumafuta kuita simba remagetsi kuburikidza ne redox reaction yeokisijeni kana zvimwe zvinooxidative. Mafuta anonyanya kushandiswa ihydrogen, iyo inogona kunzwisiswa se reverse reaction ye electrolysis yemvura kune hydrogen neokisijeni.
Kusiyana neroketi, hydrogen fuel cell haiburitse simba remagetsi kuburikidza nekuita kwakasimba kwehydrogen ne oxygen combustion, asi inoburitsa simba reGibbs free muhydrogen kuburikidza ne catalytic device. Musimboti wayo unoshanda ndewekuti hydrogen inosanganiswa kuita maerekitironi nemaion ehydrogen (maprotoni) kuburikidza ne catalyst (kazhinji platinum) mu positive electrode ye fuel cell. Mapurotoni anosvika pa negative electrode kuburikidza ne proton exchange membrane uye anoita oxygen kuti agadzire mvura nekupisa. Maerekitironi anoenderana anoyerera kubva pa positive electrode kuenda ku negative electrode kuburikidza ne external circuit kuti agadzire simba remagetsi. Haina thermal efficiency bottleneck yeinjini yemafuta inosvika 40%, uye hydrogen fuel cell inogona kusvika nyore nyore kupfuura 60%.
Kare kare, simba rehydrogen rave richizivikanwa se "chimiro chepamusoro" chemotokari itsva dzesimba nekuda kwezvakanaka zvaro zvekusasvibisa, simba rinogona kudzokororwa, hydrogenation nekukurumidza, huwandu hwakazara nezvimwewo. Zvisinei, dzidziso yehunyanzvi yehydrogen fuel cell yakakwana, asi kufambira mberi kwemaindasitiri kwaderera zvakanyanya. Chimwe chezvinetso zvikuru zvekusimudzira kwayo kudzora mutengo. Izvi zvinosanganisira kwete chete mutengo wemotokari pachayo, asiwo mutengo wekugadzira hydrogen nekuchengetedza.
Kugadzirwa kwemotokari dzinoshandisa hydrogen fuel cell kunoenderana nekuvakwa kwezvivakwa zvehydrogen fuel zvakaita sekugadzirwa kwehydrogen, kuchengetwa kwehydrogen, kutakurwa kwehydrogen uye hydrogenation. Kusiyana nematramu emhando yepamusoro, anogona kuchajwa zvishoma nezvishoma kumba kana mukambani, mota dzinoshandisa hydrogen dzinogona kuchajwa chete pachiteshi chehydrogenation, saka kudiwa kwechiteshi chekuchaja kwakakosha. Pasina network yakakwana yehydrogenation, kuvandudzwa kweindasitiri yemotokari dzinoshandisa hydrogen hakugoneki.
