Iiseli zepetroli zingahlulwahlulwa zibei-membrane yokutshintshiselana kweprotoniiseli zamafutha (i-PEMFC) kunye neeseli zamafutha ze-methanol ezithe ngqo ngokweempawu ze-electrolyte kunye namafutha asetyenzisiweyo
(DMFC), i-phosphoric acid fuel cell (PAFC), i-melt carbonate fuel cell (MCFC), i-solid oxide fuel cell (SOFC), i-alkaline fuel cell (AFC), njl. Umzekelo, ii-proton exchange membrane fuel cells (PEMFC) zixhomekeke kakhulu kwii-membrane yokutshintshiselana kweprotonukudluliselwa kweproton medium, ii-alkaline fuel cells (AFC) zisebenzisa i-alkaline water-based electrolyte efana nesisombululo se-potassium hydroxide njenge-proton transfer medium, njl. Ukongeza, ngokweqondo lobushushu lokusebenza, ii-fuel cells zinokwahlulwa zibe zii-fuel cells ezinobushushu obuphezulu kunye nee-fuel cells ezinobushushu obuphantsi, ezo zokuqala ziquka ikakhulu ii-solid oxide fuel cells (SOFC) kunye nee-metalized carbonate fuel cells (MCFC), ezi zokugqibela ziquka ii-proton exchange membrane fuel cells (PEMFC), ii-direct methanol fuel cells (DMFC), ii-alkaline fuel cells (AFC), ii-phosphoric acid fuel cells (PAFC), njl.
I-membrane yokutshintshiselana kweProtonIiseli zepetroli (i-PEMFC) zisebenzisa iimembrane ze-polymer ezisekelwe emanzini njengee-electrolytes zazo. Iiseli ze-PEMFC kufuneka zisebenze phantsi kwegesi ye-hydrogen ecocekileyo ngenxa yobushushu bazo obuphantsi bokusebenza (ngaphantsi kwe-100 ° C) kunye nokusetyenziswa kwee-electrodes zesinyithi ezibalaseleyo (ii-electrodes ezisekelwe kwi-platinum). Xa kuthelekiswa nezinye iiseli zepetroli, i-PEMFC ineengenelo zobushushu obuphantsi bokusebenza, isantya sokuqalisa ngokukhawuleza, uxinano lwamandla aphezulu, i-electrolyte engaboliyo kunye nobomi benkonzo ende. Ke ngoko, iye yaba bubuchwepheshe obuphambili obusetyenziswa ngoku kwizithuthi zeseli zepetroli, kodwa ikwasetyenziswa ngokuyinxenye kwizixhobo eziphathekayo nezizinzileyo. Ngokutsho kwe-E4 Tech, ukuthunyelwa kweeseli zepetroli ze-PEMFC kulindeleke ukuba kufike kwiiyunithi ezingama-44,100 ngo-2019, okubalwa i-62% yesabelo sehlabathi; Umthamo oqikelelweyo ofakiweyo ufikelela kwi-934.2MW, okubalwa i-83% yesabelo sehlabathi.
Iiseli zepetroli zisebenzisa ii-electrochemical reactions ukuguqula amandla eekhemikhali ukusuka kwi-fuel (hydrogen) kwi-anode kunye ne-oxidant (oxygen) kwi-cathode ibe ngumbane ukuqhuba yonke imoto. Ngokukodwa, izinto eziphambili zeeseli zepetroli ziquka inkqubo yenjini, umbane oncedisayo kunye ne-motor; Phakathi kwazo, inkqubo yenjini ibandakanya ikakhulu injini eyenziwe yi-electric reactor, inkqubo yokugcina i-hydrogen yesithuthi, inkqubo yokupholisa kunye ne-DCDC voltage converter. I-reactor yeyona nto ibalulekileyo. Yindawo apho i-hydrogen kunye ne-oxygen zisabela khona. Yenziwe ziiseli ezininzi ezidibeneyo, kwaye izinto eziphambili ziquka i-bipolar plate, i-membrane electrode, i-end plate njalo njalo.
