Amaseli kaphethiloli angahlukaniswa abei-membrane yokushintshana kweprotoniamaseli kaphethiloli (i-PEMFC) kanye namaseli kaphethiloli e-methanol aqondile ngokuya ngezakhiwo ze-electrolyte kanye nophethiloli osetshenzisiwe
(DMFC), iseli likaphethiloli le-phosphoric acid (PAFC), iseli likaphethiloli le-carbonate elincibilikisiwe (MCFC), iseli likaphethiloli le-oxide eqinile (SOFC), iseli likaphethiloli le-alkaline (AFC), njll. Isibonelo, amaseli kaphethiloli e-proton exchange membrane (PEMFC) athembele kakhulu ku-i-membrane yokushintshana kweprotoniAmaseli kaphethiloli adluliswayo, amaseli kaphethiloli e-alkaline (AFC) asebenzisa i-electrolyte esekelwe emanzini e-alkaline njengesisombululo se-potassium hydroxide njenge-proton transfer medium, njll. Ngaphezu kwalokho, ngokusho kwezinga lokushisa lokusebenza, amaseli kaphethiloli angahlukaniswa abe amaseli kaphethiloli asezingeni eliphezulu kanye namaseli kaphethiloli asezingeni eliphansi, owokuqala uhlanganisa ikakhulukazi amaseli kaphethiloli aqinile (SOFC) kanye namaseli kaphethiloli e-carbonate ancibilikisiwe (MCFC), Lawa ahlanganisa amaseli kaphethiloli e-proton exchange membrane (PEMFC), amaseli kaphethiloli e-methanol aqondile (DMFC), amaseli kaphethiloli e-alkaline (AFC), amaseli kaphethiloli e-phosphoric acid (PAFC), njll.
I-membrane yokushintshana kwe-protonAmaseli kaphethiloli (i-PEMFC) asebenzisa ama-membrane e-polymer acidic asekelwe emanzini njengama-electrolyte awo. Amaseli e-PEMFC kumele asebenze ngaphansi kwegesi ye-hydrogen emsulwa ngenxa yokushisa kwawo okuphansi kokusebenza (ngaphansi kuka-100 ° C) kanye nokusetshenziswa kwama-electrode ensimbi ahloniphekile (ama-electrode asekelwe eplatinum). Uma kuqhathaniswa namanye amaseli kaphethiloli, i-PEMFC inezinzuzo zokushisa okuphansi kokusebenza, isivinini sokuqala okusheshayo, ubuningi bamandla aphezulu, i-electrolyte engagqwali kanye nokuphila isikhathi eside kwenkonzo. Ngakho-ke, sekuwubuchwepheshe obujwayelekile obusetshenziswa njengamanje ezimotweni zamaseli kaphethiloli, kodwa futhi busetshenziswa kancane kumadivayisi aphathekayo nasebenza. Ngokusho kwe-E4 Tech, ukuthunyelwa kwamaseli kaphethiloli e-PEMFC kulindeleke ukuthi kufinyelele amayunithi angu-44,100 ngo-2019, okubalwa u-62% wesabelo somhlaba wonke; Umthamo olinganiselwe ofakiwe ufinyelela ku-934.2MW, okubalwa u-83% wesilinganiso somhlaba wonke.
Amaseli kaphethiloli asebenzisa ukusabela kwe-electrochemical ukuguqula amandla amakhemikhali kusuka kuphethiloli (i-hydrogen) ku-anode kanye ne-oxidant (i-oxygen) ku-cathode abe ugesi ukuze ashayele yonke imoto. Ngokukhethekile, izingxenye eziyinhloko zamaseli kaphethiloli zifaka phakathi uhlelo lwenjini, ukunikezwa kwamandla okusiza kanye nenjini; Phakathi kwazo, uhlelo lwenjini luhlanganisa kakhulu injini eyakhiwe yi-reactor kagesi, uhlelo lokugcina i-hydrogen yemoto, uhlelo lokupholisa kanye ne-DCDC voltage converter. I-reactor iyingxenye ebaluleke kakhulu. Yindawo lapho i-hydrogen ne-oxygen kusabela khona. Yakhiwa ngamaseli amaningi angawodwa ahlanganiswe ndawonye, futhi izinto eziyinhloko zifaka phakathi ipuleti le-bipolar, i-membrane electrode, ipuleti lokugcina njalo njalo.
