Ibyuma Byinshi - Amavuta ya selile akonje Gutangira kunoza imikorere

Ubucuruziimpumukuri ubu ni uburyo bwiza bushobora gukoreshwa kubisanzwe biruka kuri lisansi bitewe na microstructure ya porositike, imbaraga nyinshi, nimbaraga nziza za mashini.
Ubwa mbere, isesengura rya polarisiyasi ya bateri mubihe bisanzwe byakazi mubushyuhe bwicyumba. Urebye ko cathode ari electrode nyamukuru igabanya imikorere ya bateri, inzira zisanzwe zibangikanye zikoreshwa kuri anode ya selile zombi, kandi inzira zisanzwe zibangikanye zikoreshwa kuri cathode hamwe nikibuga gishya cya nikel-cyuma.
Kugirango ugaragaze neza itandukaniro ryimigendekere nibikorwa bitandukanye mumirima ibiri itemba, ubushakashatsi bwakoresheje umurima utemba utugingo ngengabuzima ufite ubunini bwa cm 1.5 × cm 20 (imyuka yose yatembaga kuruhande rurerure), ibyo bikaba byatakaje selile yumwimerere. imikorere, nuko rero, selile polarisation imikorere ntabwo yari hejuru. Mubyongeyeho, MEA imwe (Nafion-112) yakoreshejwe kuri selile zombi mugupimisha. Bitewe no kugabanuka gukabije k'umuyoboro muto utemba mu murima w'icyuma gitemba, kugabanuka k'umuvuduko ku mpande zombi ni mwinshi ugereranije n'umuyoboro woroheje ugororotse mu murima usanzwe utemba, ibyo bikaba byongera gaze kuri cathode, ikora umuvuduko, nigipimo cyibikorwa bya electrochemic reaction, kandi mugihe kimwe, bigomba gukoresha ingufu za moteri ya gaze yingutu kurwego runaka kandi byongera igihombo cya pompe. Ububasha ntarengwa buri hejuru ya selile hamweifuroimirima itemba, mugihe kumuyoboro muke, ubucucike bwimbaraga buri munsi gato ugereranije nibisanzwe bitemba. Muri rusange, ibyiza byo gukoresha icyuma gitemba icyuma kiracyafite akamaro. Mugihe kirekire, bitewe na gaze imwe hamwe namazi meza atemba mumashanyarazi atemba, umurima mugufi urashobora gukoreshwa mubikorwa bifatika, cyangwa gukoresha cathode na anode vertical cross-itanga (gazi ya anode itemba i uruhande rurerure rwumuyoboro gakondo, gazi ya cathode itembera kuruhande rugufi rwumurima wa furo), ibyo bikagabanya kandi igihombo cyo kuvoma cyatewe na cathode yinjira nigabanuka ryumuvuduko, bityo bikaba byitezwe ko bizageraho byongera imikorere ya bateri , ndetse ndetse gumana imbaraga zingana cyangwa zirenze imbaraga zirenze umuyoboro gakondo utemba, ushobora kugerwaho mugihe kirekire. Kubwibyo, byitezwe ko bizamura imikorere yimikorere ya selile mugihe gikomeza igihombo cya pompe ugereranije cyangwa kiri munsi yumurongo wa gakondo.
Kurundi ruhande, kugirango dukemure impungenge ziterwa na sub-zeru yo gutangira, turagereranya byimazeyo imikorere itangira ya selile yingufu hamwe numurongo wibyuma bitemba hamwe numuyoboro usanzwe ugereranije na cathode munsi yumuriro uhoraho kandi uhoraho.
Kurundi ruhande, kubintu bizwi cyane bya sub-zeru itangira, turagereranya byimazeyo imikorere itangirana ningirabuzimafatizo ya peteroli hamwe nicyuma gitemba cyumuyaga hamwe numuyoboro usanzwe ugereranije na cathode munsi yumuriro uhoraho kandi uhoraho.
Umwanya w'icyuma utemba werekana ibyiza bihebuje, hamwe nimikorere ihamye ya selile mugihe cyo gutangira no gutangira neza, mugihe muburyo bunyuranye, umuyoboro usanzwe wa parallel-flux selile, hamwe na selile ntoya kandi idahindagurika mugihe cyo gukora, bizamura umuvuduko wubushyuhe nubushyuhe umuvuduko wo kuzamuka kurwego runaka, ariko bitewe numuyoboro muke utemba, amahirwe yo gushushanya no gufunga yiyongera kumurongo (bitewe numubare wimiyoboro itemba), ibyo bikaba biganisha kumikorere ya selile ihindagurika Ariko, amahirwe yo gufunga urubura yiyongera kumurongo .
Muncamake, imiterere nziza yububiko bwa lisansi hamweicyumaumurima utemba ufite ibyiza byingenzi kurenza selile hamwe numuyoboro gakondo wa "trench-ridge" munsi yubushyuhe bwibyumba byombi hamwe na sub-zero dinamike yo gutangira.
Umubare ntarengwa w'amashanyarazi n'ubucucike bwa batiri ku bushyuhe bw'icyumba byiyongereyeho 25%;
Munsi ya sub-zeru itangira, imikorere ya batteri hamwe nicyuma gitemba cyumurima cyoroshye mugihe cyo gutangira, kandi ubushobozi buke bwo gutangira ubushobozi bwateye imbere cyane.
Byongeye kandi, gukoresha uburyo bunoze bwo kuvura ibikoresho byuma byinshi, nka plaque ya zahabu kugirango byongerwe neza, hydrophobicity ikwiye no kuvura ruswa, hamwe no gukoreshaibikoresho byinshihamwe nubunini bunini bwa pore ingano, porosity, hamwe na compression ratios, byitezwe ko bizakomeza gushimangira imikorere yimikorere ya selile ya lisansi no kongera igihe cyizuba gikonje.
