Iiseli zamafutha zinokwahlulwa zibeproton utshintsho inwebuiiseli zepetroli (PEMFC) kunye neeseli ze-methanol ezichanekileyo ngokweempawu ze-electrolyte kunye namafutha asetyenzisiweyo
(DMFC), phosphoric acid fuel cell (PAFC), enyibilikisiweyo carbonate fuel cell (MCFC), eqinileyo oxide fuel cell (SOFC), alkaline fuel cell (AFC), etc. Umzekelo, proton exchange inwebu iiseli fuel (PEMFC) ikakhulu bathembele kwiproton utshintsho inwebuukudlulisa iproton medium, iiseli zamafutha ealkaline (AFC) zisebenzisa ialkaline yealkaline electrolyte esekwe emanzini njengesisombululo sepotassium hydroxide njengeproton transfer medium, njl njl. Ukongeza, ngokutsho kobushushu bokusebenza, iiseli zepetroli zinokwahlulwa zibe ziiseli ezinamafutha aphezulu kunye nobushushu obuphantsi. iiseli fuel, yangaphambili iquka ikakhulu iiseli eziqinileyo oxide oxide (SOFC) kunye neeseli ezinyibilikayo carbonate fuel (MCFC), Le yokugqibela ziquka proton exchange inwebu iiseli fuel (PEMFC), iiseli methanol fuel ngqo (DMFC), iiseli ze-alkaline fuel (AFC), iiseli ze-phosphoric acid fuel (PAFC), njl.
Proton utshintsho inwebuiiseli fuel (PEMFC) zisebenzisa amanzi-based polymer inwebu ye-asidi njenge electrolytes zabo. Iiseli ze-PEMFC kufuneka zisebenze phantsi kwegesi ye-hydrogen ecocekileyo ngenxa yobushushu bokusebenza obuphantsi (ngaphantsi kwe-100 ° C) kunye nokusetyenziswa kwee-electrode zetsimbi ezihloniphekileyo (i-electrode esekelwe kwiplatinam). Xa kuthelekiswa nezinye iiseli zepetroli, i-PEMFC ineenzuzo zobushushu obuphantsi bokusebenza, isantya sokuqalisa ngokukhawuleza, ukuxinana kwamandla aphezulu, i-electrolyte engagqwaliyo kunye nobomi benkonzo ende. Ke, iye yaba yitekhnoloji yesiqhelo esetyenziswayo ngoku kwizithuthi zeeseli zamafutha, kodwa ikwasetyenziswa ngokuyinxenye kwizixhobo eziphathwayo nezimileyo. Ngokutsho kwe-E4 Tech, ukuthunyelwa kweeseli ze-PEMFC zamafutha kulindeleke ukuba kufikelele kwiiyunithi ezingama-44,100 ngo-2019, zibalelwa kwi-62% yesabelo sehlabathi; Umthamo oqikelelweyo ofakelweyo ufikelela kuma-934.2MW, nto leyo ethatha i-83% yomlinganiselo wehlabathi.
Iiseli ze-fuel zisebenzisa i-electrochemical reactions ukuguqula amandla ekhemikhali kwi-fuel (i-hydrogen) kwi-anode kunye ne-oxidant (i-oxygen) kwi-cathode ibe ngumbane ukuqhuba yonke isithuthi. Ngokukodwa, amacandelo aphambili eeseli zamafutha abandakanya inkqubo ye-injini, unikezelo lwamandla ancedisayo kunye nemoto; Phakathi kwazo, inkqubo ye-injini ikakhulu ibandakanya injini eyenziwe yi-reactor yombane, inkqubo yokugcina i-hydrogen yemoto, inkqubo yokupholisa kunye ne-DCDC yokuguqula amandla. I-reactor yeyona nto ibaluleke kakhulu. Yindawo apho ihydrogen kunye neoksijini zisabela. Iqulunqwe ngeeseli ezininzi ezidibeneyo ezidibeneyo, kwaye izinto eziphambili ziquka i-bipolar plate, i-membrane electrode, i-end plate kunye nokunye.
