Mu buryo bw'ingufu za elegitoroniki zihora zihinduka,icyuma gikozwe muri grafitiIgaragara cyane nk'ibikoresho bifite imiterere myinshi ishingiye kuri karuboni, ifite imiterere yihariye y'imiterere, amashanyarazi, na chimique. Nubwo atari ko imiterere yose y'uturemangingo twa lisansi ikoresha graphite ku isi hose, uruhare rwayo—cyane cyane mu turemangingo twa lisansi twa lisansi twateye imbere na sisitemu ya lisansi ya lisansi—yarushijeho gukurura ibitekerezo by'abahanga n'abashushanya sisitemu bihaye intego yo kunoza imikorere y'uturemangingo twa lisansi haba ku bikoresho no ku rwego rw'imikorere.
I. Ibiranga by'ibanze bya Graphite felt
Mu rwego rw'ubumenyi bw'ibikoresho, icyuma cya grafiti ni urusobe rw'imirongo itatu rugizwe n'imigozi ya karuboni ivanze, akenshi ikomoka kuri polyacrylonitrile (PAN) cyangwa ibipimo bya pitch kandi bigashyirwa kuri grafiti ku bushyuhe bwinshi. Iyi miterere itanga icyuma cya grafiti gifite imiterere itandukanye y'ingenzi cyane mu bidukikije by'amashanyarazi:
● Ingufu nyinshi z'amashanyarazi: kugenzura ko electron zitwarwa
● Ubwinshi bw'imyenge (>90%): koroshya kwinjira kwa gaze cyangwa amazi mu mazi
● Ubudahangarwa bukomeye mu kwangirika: bushobora kwifashishwa mu guhangana n’ibidukikije birimo aside/oxidation (urugero, PEMFCs)
● Ubushobozi bwiza bwo guhangana n'ingufu: butuma habaho gutuza kw'ingufu
● Ubudahangarwa bw'ubushyuhe bwinshi: bukwiriye sisitemu z'amashanyarazi zikoresha ubushyuhe bwinshi
II. Uruhare rwa Graphite Felt mu tunyangingo dutandukanye twa lisansi
Uburyo grafiti ikoreshwa mu ikoranabuhanga rya lisansi y'ibikomoka kuri peteroli buratandukanye cyane bitewe n'imiterere y'iyi sisitemu.
1. Mu mabatire anyuramo (urugero, bateri za vanadium redox flow) – Ibintu by'ingenzi bya Electrode
Mu buryo bw'amashanyarazi bukoresha amashanyarazi mu gihe cy'amazi - cyane cyane bateri zikoreshwa mu mazi, zikunze kuganirwaho hamwe n'ikoranabuhanga rya selile z'amavuta bitewe n'amahame yazo asa n'ay'amashanyarazi - icyuma cya grafiti gikoreshwa nk'igikoresho cy'ingenzi cya electrode. Ubuso bwayo bufite ubuso bwihariye n'imiterere ifite imyenge ihujwe bitanga ahantu henshi hakora ibikorwa byo gusubiramo umwuka mu gihe bitera imbere urujya n'uruza rwa electrolyte. Imikorere yo guhindura ubuso nko gukoresha ubushyuhe cyangwa oxidation ikunze gukoreshwa kugira ngo yongere ubushobozi bwayo bwo gutonyanga no gukora catalytic, bigira ingaruka ku buryo butaziguye ku mikorere myiza ya sisitemu no kudahungabana kw'uruziga.
2. Muri PEM Fuel Seli (Proton Exchange Membrane Fuel Seli) – Imfashanyigisho/Imfashanyigisho
Mu buryo bunyuranye, muri sisitemu yo gukwirakwiza porotoni (PEM), icyuma cya grafiti si amahitamo asanzwe ku gice cyo gukwirakwiza gazi (GDL). Impapuro za karuboni cyangwa igitambaro cya karuboni byiganjemo bitewe n’uburyo gikoresha neza amashanyarazi, ubukana bwa mekanike, no gukora neza. Ariko, icyuma cya grafiti cyabonye uburyo bwihariye bwo gukoresha PEM, cyane cyane aho hakenewe imicungire myiza y’amazi cyangwa ikwirakwizwa rya gazi. Ubushyuhe bwayo bwinshi bushobora kunoza imikorere yo kohereza ubwinshi bw’amazi mu gihe cy’ubushuhe bwinshi cyangwa mu gihe cy’ubushuhe bwinshi, ariko ibi bitanga inyungu mu kurwanya imikorere no kudahungabana, bigomba kwitabwaho binyuze mu kugenzura neza imiterere y’ibice n’umuvuduko.
3. Mu byuma bitanga lisansi bishyushye cyane (SOFCs, nibindi) – Ifuru y'inyongera ikoresha amashanyarazi/ifunga
Mu buryo bushyuha cyane (urugero: electrolyzers za okiside ikomeye), graphite felt ntabwo ikoreshwa nk'igice cy'ingenzi cya electrochemical bitewe n'ubwiganze bw'ibikoresho bya ceramic muri electrodes na electrolyte. Ariko, ishobora gukora imirimo y'inyongera, harimo gufunga amashanyarazi, gushyigikira gufunga, cyangwa kwakira kwaguka k'ubushyuhe mu bikoresho by'inyongera cyangwa mu duce duhuza imiterere. Nubwo iyi mirimo ari iya kabiri, ni ingenzi cyane mu gutuma habaho kuramba igihe kirekire no kuba imikorere myiza mu gihe cy'imikorere mibi.
III. Incamake y'Inshingano z'ingenzi mu Ikoranabuhanga rya Seli za Fuel
Mu rwego rw’ubuhanga mu mikorere, agaciro ka grafiti ikoze mu ikoranabuhanga gashingiye ku bushobozi bwayo bwo guhuza imirimo myinshi mu kintu kimwe. Imiterere yayo y’ibice bitatu ituma habaho uburyo bwo guhuza amashanyarazi, bikongera neza agace k’imikorere idakomeje kwiyongera cyane. Muri icyo gihe, igira uruhare mu gukwirakwiza amazi mu buryo bumwe, igagabanya ubukana bw’ibice kandi ikagabanya igihombo cya polarization gifitanye isano n’imbogamizi zo kohereza ibintu byinshi. Guhuza neza grafiti ikoze mu ikoranabuhanga byoroshya ishyirwaho ry’umuyoboro uhoraho w’amashanyarazi, bityo bikagabanya ubukana bw’imbere mu mubiri kandi bikanoza imikorere myiza ya sisitemu muri rusange.
Byongeye kandi, igira uruhare runini mu kunoza imikorere ya mekanike n'iy'iteranya. Kuba grafiti ikora neza kandi igakomeza gukomera bituma ibasha kwihuza n'uburyo ikora kandi igakomeza gukorana neza mu gihe cyo gukusanya. Iki kintu ni cyiza cyane mu buryo bwa modular cyangwa bunini, kuko gukwirakwiza kimwe ari ingenzi kugira ngo imikorere irusheho kuba myiza.
IV. Kuki wahitamo VET Energy?
Mu rwego rw'uturemangingo twa lisansi n'ibindi bijyanye nabyo bikoreshwa mu bushyuhe bwinshi, VET Energy, ikoresheje ubunararibonye bwayo buhoraho mu bushakashatsi no mu ikoranabuhanga mu bikoresho bishingiye kuri karuboni, yubatse sisitemu yuzuye y'ibicuruzwa bya grafiti n'ibikoresho bivanze bikubiyemo ibintu bitandukanye bikoreshwa, itanga ibisubizo byihariye ku bwoko butandukanye bw'uturemangingo twa lisansi. Ibisubizo by'ibikoresho bya VET Energy byakoreshejwe cyane mu ikoranabuhanga ritandukanye, harimo uturemangingo twa lisansi twa proton exchange membrane na turemangingo twa lisansi twa oxide, kandi byazamuwe kandi byemezwa mu buryo bwagutse nka bateri zikoreshwa. Niba urimo gusuzuma ubushobozi bwo gukoreshaicyuma gikozwe muri grafitin'ibikoresho bifitanye isano na karuboni mu buryo bw'amashanyarazi, cyangwa wifuza kunoza imikorere n'imikorere isanzweho, mwatwandikira kugira ngo tuganire kandi dufatanye guteza imbere iterambere ry'ikoranabuhanga rya lisansi y'ibikomoka kuri peteroli.
