Igipande cy’ibipolar ni cyo gice cy’ingenzi cy’icyuma gitera umwuka, bigira ingaruka zikomeye ku mikorere n’ikiguzi cyacyo. Kuri ubu, igipande cy’ibipolar gigabanyijemo ibice bibiri: graphite, composite plate n’icyuma hakurikijwe ibikoresho.
Igipande cya Bipolar ni kimwe mu bice by'ingenzi bya PEMFC, inshingano yacyo nyamukuru ni ugutwara gazi mu butaka, gukusanya no kuyobora umuyoboro w'amazi, ubushyuhe n'amazi biva mu gikorwa. Bitewe n'ubwoko bw'ibikoresho, uburemere bw'ibice bya PEMFC ni hagati ya 60% na 80% kandi ikiguzi ni hafi 30%. Dukurikije ibisabwa ku mikorere ya gipande cya bipolar, kandi ukurikije ibidukikije bya PEMFC, igipande cya bipolar gisabwa kugira ibisabwa byinshi mu gutwara amashanyarazi, gukomera k'umwuka, imiterere ya mekanike, kurwanya ingese, nibindi.
Ibyuma bibiri bigizwe ahanini n’ibice bitatu, plaque ya grafiti, plaque ivanze, plaque y’icyuma, plaque ebyiri ya grafiti niyo ikoreshwa cyane muri iki gihe. PEMFC, plaque ebyiri zo mu rugo, amashanyarazi, amashanyarazi, ubwiza no kurwanya ingese hamwe n’indi mikorere ariko imiterere mibi ya mekanike, imbogamizi zo kwangirika no gukora imashini bitera ibibazo bihendutse byugarijwe n’inganda nyinshi.
Grafitiplaque y'ibipolarIntangiriro:
Amasahani ya Bipolar akozwe muri grafiti afite ubushobozi bwo gutwara amashanyarazi neza, ubushobozi bwo gutwara ubushyuhe no kurwanya ingese, kandi ni yo masahani ya bipolar akoreshwa cyane muri PEMFCS. Ariko, ingaruka mbi zayo nazo ziragaragara cyane: ubushyuhe bwa grafiti busanzwe buri hejuru ya 2500℃, bugomba gukorwa hakurikijwe uburyo bwo gushyushya buhamye, kandi igihe ni kirekire; Uburyo bwo gukora buragenda buhoro, uruziga ni rurerure, kandi ubwiza bw'imashini ni bwinshi, bigatuma igiciro cya grafiti gihenda cyane; Grafiti ni ndende, icyuma cyarangiye kigomba gufatwa neza, guteranya biragoye; Grafiti ifite imyenge, bityo amasahani agomba kuba afite ubugari bwa milimetero nke kugira ngo imyuka ishobore gutandukana, bigatuma ubucucike bw'ibikoresho ubwabyo buba buke, ariko bikaba ibicuruzwa biremereye.
Gutegura grafitiplaque y'ibipolar:
Ifu ya toner cyangwa grafiti ivangwa na resin ya grafiti, igashyirwamo, hanyuma igashyirwamo grafiti ku bushyuhe bwinshi (ubusanzwe kuri 2200 ~ 2800C) mu kirere giciriritse cyangwa mu gihe cy'umwuka udafite umwuka. Hanyuma, icyuma cya grafiti gishyirwamo umwuka kugira ngo gifunge umwobo, hanyuma imashini igenzura imibare igakoreshwa mu gutunganya inzira ikenewe ya gaze ku buso bwayo. UBUSHYUHE BUKURU BWA GRAPHITIZATION N'IMIYOBORO YA GAZI NIYO MPAMVU NYAMUKURU ZITUMA IBICURUZWA BYA BIPOLAR BIDASHYIRA HAFI, MU MIYOBORO IFITE HAFI 60% BY'IGICIRO CYOSE CYA SUEL CELL.
Igipande cy'ibipolarni kimwe mu bice by'ingenzi cyane mu gice cy'uturemangingo twa lisansi. Imirimo yacyo y'ingenzi ni iyi ikurikira:
1, Guhuza bateri imwe
2. Gutanga lisansi (H2) n'umwuka (02)
3. Gukusanya no gukoresha ubu
4, inkingi yo gushyigikira na MEA
5. Gukuraho ubushyuhe buterwa n'ingaruka
6. Kuramo amazi yakozwe mu buryo bwo gukora
