Ingufu za hydrogen na graphite bipolar plate

Muri iki gihe, ibihugu byinshi bikikije impande zose z’ubushakashatsi bushya bwa hydrogen biri mu nzira ikomeye, ingorane za tekiniki ziri mu nzira yo kubyikemurira. Bitewe no kwaguka gukomeye k’urwego rw’ingufu za hydrogen, ibikorwa remezo byo kubika no gutwara, ikiguzi cy’ingufu za hydrogen nacyo gifite umwanya munini wo kugabanuka. Ubushakashatsi bwerekana ko ikiguzi rusange cy’uruhererekane rw’ingufu za hydrogen cyitezwe kugabanukaho kimwe cya kabiri mu 2030. Nk’uko raporo yashyizwe ahagaragara ku bufatanye na Komisiyo Mpuzamahanga ishinzwe Ingufu za Hydrogen na McKinsey ibigaragaza, ibihugu birenga 30 n’uturere byashyize ahagaragara gahunda yo guteza imbere ingufu za hydrogen, kandi ishoramari ku isi mu mishinga y’ingufu za hydrogen rizagera kuri miliyari 300 z’amadolari y’Amerika mu 2030.

Agace k'uturemangingo twa lisansi ya hydrogen kagizwe n'uturemangingo twinshi twa lisansi dushyizwe hamwe mu buryo butandukanye.Igipande cy'ibipolar plate na membrane electrode MEA birahurirana, kandi ibifunga bishyirwa hagati ya buri monomer. Nyuma yo gukandagirwa n'ibipande by'imbere n'inyuma, birahambirwa kandi bigahambirwa n'amakuru kugira ngo bikore agace k'uturemangingo twa hydrogen fuel.

Igikoresho cya bipolar plate na membrane electrode MEA birahurirana, kandi ibifunga bishyirwa hagati ya buri monomer. Nyuma yo gukandagirwa n'ibice by'imbere n'inyuma, bihambirwa kandi bigahambirwa n'amakuru kugira ngo bikore agace k'uturemangingo twa hydrogen fuel. Kuri ubu, ikoreshwa nyaryo niIcyapa cy'ubuhumekero gikozwe muri grafiti y'ubukorano.Igikoresho cya bipolar plate cyakozwe muri ubwo bwoko bw'ibikoresho gifite ubushobozi bwo gutwara ibintu neza no kurwanya ingese. Ariko, bitewe n'ibisabwa kugira ngo icyuma cya bipolar plate gikomeze gufunga umwuka, igikorwa cyo kugikora gikenera ibikorwa byinshi nko gutera resin, gushyiramo karubone, gushyiramo grafiti ndetse no gutunganya flow field nyuma yaho, bityo uburyo bwo kugikora ni bugoye kandi igiciro ni kinini cyane, byabaye ikintu cy'ingenzi kibuza ikoreshwa rya lisansi.

Ururenda rw'ihererekanya rya porotoniSelile y'ibikomoka kuri peteroli (PEMFC) ishobora guhindura ingufu za shimi mu buryo butaziguye ingufu z'amashanyarazi mu buryo bwa isothermal na electrochemical. Ntabwo igengwa na Carnot cycle, ifite igipimo cyo guhindura ingufu nyinshi (40% ~ 60%), kandi isuku kandi nta mwanda (ibicuruzwa ahanini ni amazi). Ifatwa nk'uburyo bwa mbere bwo gutanga ingufu nziza kandi zisukuye mu kinyejana cya 21. Nk'igice gihuza uturemangingo twinshi muri PEMFC stack, bipolar plate ahanini igira uruhare mu gutandukanya impuzandengo hagati y'uturemangingo, gukwirakwiza lisansi na okisideri, gushyigikira electrode ya membrane no guhuza uturemangingo twinshi mu buryo bukurikiranye kugira ngo habeho electron circuit.
