Ingufu za hydrogen hamwe na plaque bipolar plate

Kugeza ubu, ibihugu byinshi bikikije impande zose z’ubushakashatsi bushya bwa hydrogène birakomeje, ingorane za tekinike mu guhaguruka ngo tuneshe. Hamwe no kwaguka kwinshi kwingufu za hydrogène itanga umusaruro nububiko n’ibikorwa remezo byo gutwara abantu, igiciro cy’ingufu za hydrogène nacyo gifite umwanya munini wo kugabanuka. Ubushakashatsi bwerekana ko muri rusange hateganijwe ko igiciro rusange cy’inganda zikoresha ingufu za hydrogène kizagabanukaho kimwe cya kabiri mu 2030. Nk’uko raporo yashyizwe ahagaragara na komisiyo mpuzamahanga ishinzwe ingufu za hydrogène na McKinsey ibivuga, ibihugu n’uturere birenga 30 byashyize ahagaragara igishushanyo mbonera cy’iterambere ry’ingufu za hydrogène, n'ishoramari ku isi mu mishinga y'ingufu za hydrogène rizagera kuri miliyari 300 z'amadolari ya Amerika muri 2030

Amavuta ya hydrogène selile igizwe na selile nyinshi za selile zegeranye zikurikirana.Icyapa cya bipolar na membrane electrode MEA iruzuzanya, kandi kashe yashyizwe hagati ya buri monomer. Nyuma yo gukanda ku isahani yimbere ninyuma, barayizirika kandi bayizirikaho imigozi kugirango babe ingirabuzimafatizo ya hydrogène.

Isahani ya bipolar na membrane electrode MEA iruzuzanya, kandi kashe yashyizwe hagati ya buri monomer. Nyuma yo gukanda kumasahani yimbere ninyuma, barayiziritse kandi bayomekaho imigozi kugirango babe ingirabuzimafatizo ya hydrogène. Kugeza ubu, gusaba nyirizina niisahani ya bipolar ikozwe muri grafite.Isahani ya bipolar ikozwe muri ubu bwoko ifite ibikoresho byiza kandi birwanya ruswa. Nyamara, bitewe nibisabwa kugirango ikirere gikomere cyane kuri plaque bipolar, inzira yo gukora ikenera inzira nyinshi zibyara umusaruro nko gutera inda, karuboni, gushushanya no gutunganya imirima ikurikira, bityo rero uburyo bwo gukora buragoye kandi ikiguzi ni kinini cyane, Ifite ube ikintu cyingenzi kibuza ikoreshwa rya selile.

Guhindura protonselile ya lisansi (PEMFC) irashobora guhindura ingufu za chimique ingufu zamashanyarazi muburyo bwa isothermal na electrochemic. Ntabwo igarukira kuri Carnot cycle, ifite umuvuduko mwinshi wo guhindura ingufu (40% ~ 60%), kandi ifite isuku kandi idafite umwanda (ibicuruzwa ahanini ni amazi). Bifatwa nkuburyo bwa mbere bukora neza kandi busukuye bwo gutanga amashanyarazi mu kinyejana cya 21. Nkibice bigize selile imwe murwego rwa PEMFC, plaque bipolar igira uruhare runini mugutandukanya gaze hagati ya selile, gukwirakwiza lisansi na okiside, gushyigikira electrode ya membrane no guhuza selile imwe murukurikirane kugirango ibe umuzenguruko wa elegitoroniki.
