Amaseli amafutha angahlukaniswa abeI-membrane ye-proton exchangeama-fuel cell (PEMFC) futhi aqondise amaseli kaphethiloli e-methanol ngokuya ngezakhiwo ze-electrolyte nophethiloli osetshenzisiwe
(DMFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC), solid oxide fuel cell (SOFC), alkaline fuel cell (AFC), njll. Isibonelo, i-proton exchange membrane fuel cell (PEMFC) ithembele kakhulu kuI-membrane ye-proton exchangedlulisa i-proton medium, ama-alkaline fuel cell (AFC) asebenzisa i-electrolyte esekelwe emanzini ane-alkaline njengesixazululo se-potassium hydroxide njengendlela yokudlulisa i-proton, njll. Ngaphezu kwalokho, ngokusho kwezinga lokushisa elisebenzayo, amaseli kaphethiloli angahlukaniswa ngamaseli okushisa aphezulu kanye nezinga lokushisa eliphansi. amaseli kaphethiloli, owokuqala ahlanganisa ikakhulukazi ama-solid oxide fuel cell (SOFC) namaseli kaphethiloli we-carbonate ancibilikisiwe (MCFC), Lawa ahlanganisa i-proton exchange membrane fuel cell (PEMFC), amaseli e-methanol fuel cell (DMFC), ama-alkaline fuel cell (AFC), I-phosphoric acid fuel cell (PAFC), njll.
I-membrane yokushintshanisa i-protonama-fuel cell (PEMFC) asebenzisa ulwelwesi lwe-acidic polymer olusekelwe emanzini njengama-electrolyte awo. Amaseli e-PEMFC kufanele asebenze ngaphansi kwegesi ye-hydrogen emsulwa ngenxa yamazinga okushisa aphansi okusebenza (angaphansi kuka-100 ° C) kanye nokusetshenziswa kwama-electrode ensimbi ahloniphekile (ama-electrode asekelwe eplatinamu). Uma kuqhathaniswa namanye amaseli kaphethiloli, i-PEMFC inezinzuzo zokushisa okuphansi kokusebenza, isivinini sokuqalisa ngokushesha, ukuminyana kwamandla aphezulu, i-electrolyte engagqwali kanye nempilo ende yesevisi. Ngakho-ke, isiphenduke ubuchwepheshe obujwayelekile okwamanje obusetshenziswa ezimotweni zamangqamuzana kaphethiloli, kodwa futhi isetshenziswa kancane kumadivayisi aphathekayo kanye nalawo amile. Ngokusho kwe-E4 Tech, ukuthunyelwa kwamaseli kaphethiloli e-PEMFC kulindeleke ukuthi kufinyelele kumayunithi angama-44,100 ngo-2019, okubalelwa ku-62% wesabelo somhlaba wonke; Isilinganiso somthamo ofakiwe sifinyelela ku-934.2MW, okwenza ama-83% engxenye yomhlaba wonke.
Amaseli kaphethiloli asebenzisa ukusabela kwe-electrochemical ukuguqula amandla amakhemikhali asuka kuphethiloli (i-hydrogen) ku-anode kanye ne-oxidant (i-oxygen) ku-cathode ibe ugesi ukuze ishayele yonke imoto. Ngokukhethekile, izingxenye eziyinhloko zamaseli kaphethiloli zifaka isistimu yenjini, ukunikezwa kwamandla okusizayo kanye nemoto; Phakathi kwazo, uhlelo lwenjini ikakhulukazi luhlanganisa injini eyakhiwe i-reactor kagesi, isistimu yokugcina i-hydrogen yemoto, uhlelo lokupholisa kanye ne-DCDC voltage converter. I-reactor iyingxenye ebaluleke kakhulu. Yindawo lapho i-hydrogen nomoya-mpilo kusabela khona. Yakhiwe ngamaseli amaningi angawodwa ahlanganiswe ndawonye, futhi izinto eziyinhloko zihlanganisa ipuleti le-bipolar, i-electrode ye-membrane, i-end plate nokunye.
