Ipuleti le-bipolar, elaziwa nangokuthi ipuleti lokuqoqa, lingenye yezingxenye ezibalulekile zeseli likaphethiloli. Linemisebenzi nezakhiwo ezilandelayo: ukuhlukanisa uphethiloli kanye ne-oxidizer, ukuvimbela ukungena kwegesi; Ukuqoqa nokuqhuba ugesi, ukuhanjiswa kwamandla aphezulu; Isiteshi sokugeleza esakhiwe futhi sacutshungulwa singasabalalisa igesi ngokulinganayo engqimbeni yokusabela ye-electrode yokusabela kwe-electrode. Kunezinqubo eziningana zokugoqa zamapuleti e-bipolar e-graphite.
1, indlela yokugoqa ipuleti enezingqimba eziningi:
Inqubo yokusebenza yomshini wokugoqa oqhubekayo onezingqimba eziningi: i-veneer ikhishwa endukwini yokugoqa i-veneer, kanye ne-glue ezinhlangothini zombili zomhlabathi nge-roller yokumboza i-binder, kanye ne-winding roll kanye ne-veneer kuhlanganiswa kube yipuleti elinobukhulu obuthathu, bese igebe phakathi kwama-roller ligoqwa libe ugqinsi oluthile. Bese ufaka ku-heater ukuze kufudumale futhi kome. Ngokulawula ukujiya, goqa, lungisa ukujiya ukuze kufinyelele usayizi ocacisiwe, bese uthumela kudivayisi yokugoqa ukuze igoqwe. Lapho i-binder ishiswa i-carbon, ekugcineni icindezelwa ibe sesimweni nge-pressure roller.
Kusetshenziswa indlela yokugoqa eqhubekayo, ipuleti le-graphite eliguquguqukayo elinobukhulu obungu-0.6-2mm lingacindezelwa, okungcono kunomshini wokugoqa onesendlalelo esisodwa, kodwa ngenxa yobukhulu bepuleti kuzoletha nokushiyeka kokuhlukaniswa kwepuleti ngezingqimba, okuzoletha inkinga ekusetshenzisweni. Isizathu ukuthi ukugcwala kwegesi kuhlala phakathi kwesendlalelo ngesikhathi sokucindezela, okuvimbela ukubophana okuseduze phakathi kwezingqimba. Indlela yokuthuthukisa ukuxazulula inkinga yegesi yokukhipha umoya enqubweni yokucindezela.
Ukugoqa ipuleti elinongqimba olulodwa, yize ipuleti lokucindezela libushelelezi, kodwa alilikhulu kakhulu. Uma ukubumba kukhulu kakhulu, ukufana nobuningi balo kunzima ukuqinisekisa. Ukuze kwenziwe amapuleti aqinile, amabhodi anezingqimba eziningi afakwa phezulu bese ecindezelwa emabhodini ahlanganisiwe anezingqimba eziningi. I-binder ifakwa phakathi kwezingqimba ezimbili ngayinye bese igoqwa. Ngemva kokwakheka, iyashiswa ukuze i-binder ibe yi-carbon futhi iqine. Indlela yokugoqa ipuleti elinezingqimba eziningi yenziwa emshinini wokugoqa oqhubekayo onezingqimba eziningi.
2, indlela yokugoqa okuqhubekayo yepuleti elingqimba olulodwa:
Isakhiwo se-roller siqukethe: (1) i-hopper ye-graphite ye-worm; (2) Idivayisi yokudla ngokudlidliza; (3) Ibhande lokudlulisa; (4) Ama-roller amane okucindezela; (5) Ipheya lama-heater; (6) i-roller yokulawula ukujiya kweshidi; Ama-roller okufaka i-embossing noma amaphethini; (8) kanye ne-roll; (9) Ummese wokusika; (10) I-roll yomkhiqizo oqediwe.
Le ndlela yokugoqa ingacindezela i-graphite eguquguqukayo ibe amashidi ngaphandle kwe-binder, futhi yonke inqubo yenziwa ngemishini ekhethekile efakwe ama-roller roller.
Inqubo yokusebenza: i-graphite emsulwa kakhulu ingena kudivayisi yokondla isuka kwi-hopper bese iwela ebhandeni lokuhambisa. Ngemva kokugingqika kwe-roller yokucindezela, kwakha ukujiya okuthile kwengqimba yezinto ezibonakalayo. Idivayisi yokushisa ikhiqiza ukushisa okuphezulu ukuze kususwe igesi esele kungqimba yezinto ezibonakalayo futhi kwandiswe i-graphite enganwetshwa okokugcina. Ngemuva kwalokho izinto eziphambene ezakhiwe ekuqaleni zifakwa ku-roller elawula usayizi wokujiya bese zicindezelwa futhi ngokosayizi ocacisiwe ukuze kutholakale ipuleti eliyisicaba elinobukhulu obufanayo kanye nobuningi obuthile. Ekugcineni, ngemva kokusika ngomsiki, goqa umgqomo oqediwe.
Lokhu okungenhla inqubo yokugoqa yokubumba i-graphite bipolar plate, ngithemba ukukusiza. Ngaphezu kwalokho, izinto ze-carbonaceous zifaka i-graphite, izinto ze-carbon ezibunjiwe kanye ne-graphite enwetshiwe (eguquguqukayo). Ama-bipolar plate avamile enziwe nge-graphite ende futhi afakwe eziteshini zokugeleza kwegesi. I-graphite bipolar plate inezakhiwo zamakhemikhali ezizinzile kanye nokumelana okuncane kokuthintana ne-MEA.
