Ukwerekanwa kw'ibicuruzwa
- Mu bijanye n’inguvu z’ubu, ububiko bw’inguvu ku rugero runini buragenda buragira akamaro kanini. Kandi mu bikoresho vyose vy’ingenzi, graphite - cane cane graphite bipolar plates - iriko iraronka ivyiyumviro vyinshi nk’igice nyamukuru mu buryo bwo kubika inguvu. Kubera ko ico kintu gifise akamaro kadasanzwe mu bijanye n’ugukora neza, caratumye habaho iterambere ry’ubuhinga nyaryo mu bijanye n’ubuhinga bwo kubika inguvu.
Ikibanza c'igicuruzwa
- Mu bikoresho vyo kubika inguvu z'umuyagankuba, izo nkoko zibiri zitwa "umutima" w'urutonde, zikora ibikorwa vyinshi bihambaye. Ntibikeneye gusa gutanga inzira nziza y’ugutwara umuriro kugira ngo umuriro ugere ku buryo bumwe, ariko kandi bitegerezwa kuba bifise inkomezi zihagije zo gushigikira ikirundo cose, kandi bitegerezwa kuba bishobora kunanira ukubora kw’umuyagankuba kugira ngo bishobore gukora igihe kirekire-.
- Ikintu kidasanzwe c’amasahani abiri y’ibara ry’agahama y’ubusuku bwinshi -ari mu bushobozi bwayo bwiza cane. Ugereranije n’ibindi bikoresho, graphite irafise ubushobozi bwiza cane bwo gutwara umuyagankuba, ifise ubushobozi bwo gutwara umuyagankuba bushika kuri 150-200 S/cm, ikaba yegera urugero rw’ibikoresho bimwebimwe vy’ivyuma. Muri ico gihe nyene, ibikoresho vy’ibara ry’agahama vyerekana ko bikomeye cane mu bijanye n’imiti, bikaba biguma bikora ataco bihinduye mu bidukikije bifise aside ikomeye canke alkali ikomeye. Vyongeye, graphite irafise ubushuhe bwiza, ishobora guhindura ubushuhe buva mu gihe ikoreshwa.

Iciyumviro: Igicuruzwa cemera guhindura uko umuntu ashaka
Ikiranga igicuruzwa
Ikintu nyamukuru kiranga isahani y’ibipande bibiri vy’ibara ry’agahama ry’ubusuku bwinshi-ni ubusuku bwayo. Uko ubusuku buzoba bwinshi, ni ko n’ubushobozi bw’ico kintu buzoba bwiza. Muri rusangi, umuyagankuba uri mu bikoresho vy’amabuye y’agaciro ni 99,5% canke 99,9%. Iyo ivyuma vy’umuyagankuba bishitse ku bice bine (99,9%) canke bitanu (99,999%), bica bihinduka ico twita igicuruzwa c’ubusuku bwinshi-. Hakoreshejwe mwene iyo graphite isukuye mu guhingura no guhingura, iyo graphite izogira ibintu vyinshi, nk’ugushobora gutwara ubushuhe, gutwara umuyagankuba, guhangana n’ugusenyuka be n’ugushikama.
Ibisabwa
I. Inganda zikora imiti n'ivyuma
Ivyuma bikoresha umuyagankuba n’ibikoresho bikora: Mu bijanye n’ubuhinga bwa chlor-alkali, graphite ni yo ikoreshwa cane nk’ibikoresho vy’umuyagankuba vy’ivyuma bikoresha umuyagankuba. Ikintu ni uko, ubushobozi bwayo bwiza cane bwo guhangana n’ugusenyuka butuma ishobora guhangana n’ivyo bidukikije bikomeye vy’aside n’ivy’amazi, ivyo na vyo bikaba bifasha kwagura cane ubuzima bw’ibikoresho.
Ibikoresho vy'ubucuzi bw'ivyuma: Bikoreshwa kandi nk'ibikoresho vyo gutera canke ibipfukisho vy'ubushuhe bwinshi-. Igituma igaragara aha ni ubushuhe bwayo bukomeye-ishobora guhangana n’ubushuhe burenze degre 2000 mu buryo bworoshe, kandi ivyo ni ngirakamaro cane ku migenderanire y’ugushonga ivyuma.
II. Gukora ibikoresho vy'amashanyarazi
Ama switch y’umuriro mwinshi{0}}n’ibikoresho bigabanya umuriro: Kubera ubushobozi bwayo bwiza bwo gutwara umuriro n’inkomezi zikomeye z’ubuhinga, graphite yacitse ihitamwo ryiza ry’ibikoresho vy’umuriro mwinshi-. Nk’akarorero, birashobora gufasha kugabanya ukubura kw’umuriro mu bikoresho bica umuriro, bigatuma ivyo bikoresho bikora neza.
Uburyo bwo kubika inguvu: Mu bikoresho vy’amashanyarazi n’amabateri ya litiyumu-ion, graphite ikora nk’ikintu c’amashanyarazi. Ivyo mu vy’ukuri birafasha kwongerera ubushobozi amabateri kandi bikaba bituma n’ubushobozi bwo gucagura no gukuraho amabateri butera imbere.
III. Ugukingira ibidukikije no gusubira gukoresha ibikoresho
Gusukura amazi mabi: Mu bikoresho vyo gusukura amazi mabi bikoresheje ubuhinga bw’amashanyarazi, graphite ikora biciye ku guhindura amazi mabi kugira ngo isenyure ibintu bihumanya. Ivyo ntibisukura neza amazi mabi gusa, ariko kandi birafasha no kugabanya amahera yo kuyasukura.
Uguhingura ihydrogène n’ukubika inguvu: Kubera iterambere rikomeye- ry’ubuhinga bwo gukoresha amazi mu guhingura ihydrogène, ugushaka graphite kuraguma kwiyongera-cane cane mu buryo bwo kubika inguvu zishobora gusubirwamwo, aho ifise uruhara runini.
IV. Inguvu nshasha n'ubuhinga bushasha
Bateri za litiyumu-ion n’ibikoresho bikomeye cane: Mu bikoresho vy’inguvu z’amabateri, uburebure bw’ubutaka bwihariye bwa graphite n’ubushobozi bwiza bwo gutwara umuyagankuba bituma igikorwa co kwinjiza no gukuraho litiyumu-ion kigenda neza, ivyo bikaba bituma amabateri akora neza muri rusangi.
Ivyuma vy’izuba: Mu bijanye n’amashanyarazi, bikoreshwa nk’igikoresho co gufasha amashanyarazi. Ivyo ntibifasha gusa guhindura neza amashanyarazi y’umuyagankuba, ariko kandi, kubera ko ishobora guhangana n’ibihe vyiza, bituma ishobora kumenyera ibidukikije bikomeye vyo hanze, bikagabanya ivy’ugusanasana kenshi be n’amahera ajanye navyo.
V. Ivyuma vyo mu kirere n’ivyo mu buvuzi
Biroroshe kandi bikomeye cane: Mu bihimba vy’indege zo mu kirere, graphite iriko irasubirira ibikoresho vya kera vy’ivyuma. Ivyo ntibigabanya gusa uburemere bwose bw’ico kirere, ariko kandi biratuma gishobora guhangana n’ubushuhe, ivyo bikaba ari ngirakamaro mu bikorwa vyo mu kirere.
Biocompatibility: Ku bijanye n’ibikoresho vy’ubuvuzi nk’ibikoresho bishobora guterwa mu mubiri, ibikoresho vya graphite ntibigira ubumara kandi ntibishobora gusenyuka-ivyo bituma bishobora gukoreshwa igihe kirekire mu mubiri w’umuntu.
Ingorane z'ubuhinga
Naho amabarabara y’ivyuma bita graphite afise ivyiza vyinshi, aracari n’ingorane zimwezimwe zo mu vy’ubuhinga. Ikibazo c’ugusenyuka cama ari ikibazo ku gukoresha ibikoresho vya graphite, cane cane mu bikoresho vy’amavuta binini, aho amasahani abiri akeneye kwihanganira umukazo munini wo gukoranya.Ikindi kibazo ni ukugenzura igiciro. Igiciro c’ibikoresho vya graphite vy’ubusuku bwinshi-ni kinini cane, kandi kubera ibisabwa kugira ngo bikoreshwe neza, igiciro c’amasahani y’ibipande bibiri gifise igice kinini c’igiciro cose c’urutonde.
