Ihame ry'imikorere n'ibyiza bya hydrogen fuel cell stack

Seli ya lisansil ni ubwoko bw'igikoresho gihindura ingufu, gishobora guhindura ingufu za electrochemical za lisansi mo ingufu z'amashanyarazi. Cyitwa lisansi kuko ari igikoresho gitanga ingufu za electrochemical hamwe na bateri. Akanyabutabire gakoresha hydrogen nk'amavuta ni hydrogène fuel cell. Akanyabutabire gashobora kumvikana nk'uburyo electrolysis y'amazi ihinduka hydrogen na ogisijeni. Uburyo hydrogène fuel cell ikora ni bwiza kandi bunoze. Akanyabutabire gashobora kugabanywa n'ubushobozi bwa 42% by'ubushyuhe bwa Carnot cycle ikoreshwa muri moteri y'imodoka isanzwe, kandi ubushobozi bushobora kugera kuri 60%.

Bitandukanye na roketi, uturemangingo twa hydrogene dukora ingufu za kinetic binyuze mu buryo bukomeye bwa hydrogene na ogisijeni, kandi tugasohora ingufu za Gibbs muri hydrogene binyuze mu bikoresho bya catalytic. Ingufu za Gibbs ni ingufu za electrochemical zirimo entropy n'izindi nyigisho. Ihame ry'imikorere rya hydrogene fuel cell ni uko hydrogen ihinduka iyoni za hydrogene (ni ukuvuga protons) na electron binyuze muri catalyst (Platinum) muri electrode nziza y'akaremangingo. Iyoni za hydrogène zinyura mu membrane ya proton zijya kuri electrode negative hanyuma ogisijeni igakora ikaba amazi n'ubushyuhe, kandi electron zijyanye nazo zituruka kuri electrode negative zijya kuri electrode negative binyuze mu ruziga rwo hanze kugira ngo zikore ingufu z'amashanyarazi.

Muriububiko bw'uturemangingo twa lisansi, imikorere ya hydrogen na ogisijeni irakorwa, kandi habaho kwimura umuriro muri icyo gikorwa, bigatera umuriro. Muri icyo gihe, hydrogen ikorana na ogisijeni kugira ngo itange amazi.
Nk'ikigega cy'ubuhanga bw'ibinyabutabire, ikoranabuhanga ry'ingenzi ry'ifatizo ry'uturemangingo twa lisansi ni "urukiramende rwo guhererekanya porotoni". Impande ebyiri za firime zegereye urwego rwa catalyst kugira ngo ziboze hydrogen mo iyoni zishyushye. Kubera ko molecule ya hydrogen ari nto, electron zitwara hydrogen zishobora kunyura mu mwobo muto wa firime. Ariko, mu gihe electron zitwara hydrogen zinyura mu mwobo wa firime, electron zikurwa muri molecules, hagasigara gusa porotoni za hydrogen zishyushye neza kugira ngo zigere ku rundi ruhande binyuze muri firime.
Porotoni za hydrogèneBikururwa na electrode iri ku rundi ruhande rwa filime kandi bihurirana na molekile za ogisijeni. Amasafuriya ya electrode ku mpande zombi za filime agabanya hydrogen mo ions nziza za hydrogen na electrons, maze agacamo ogisijeni mo atome za ogisijeni kugira ngo afate electrons maze azihindure ions za ogisijeni (amashanyarazi mabi). Electron zikora umuyoboro w'amashanyarazi hagati ya electrode, maze ions ebyiri za hydrogen na ion imwe ya ogisijeni bihurira hamwe bigakora amazi, aba ari yo "myanda" yonyine mu gikorwa cyo gusubiza. Muri make, igikorwa cyose ni igikorwa cyo gutanga ingufu. Uko ogisijeni igenda itera imbere, electrons zihora zimurwa kugira ngo zikore umuyoboro w'amashanyarazi ukenewe kugira ngo utware imodoka.
