Kumenyekanisha ingufu za hydrogène na selile

Ingirabuzimafatizo zishobora kugabanywamoproton yo guhanaselile ya lisansi (PEMFC) hamwe na methanol ya lisansi ikurikije imitungo ya electrolyte na lisansi yakoreshejwe

. (DMFC) kuproton yo guhanaihererekanyabubasha rya proton, selile ya alkaline (AFC) ikoresha electrolyte ishingiye kumazi ya alkaline nka hydroxide ya potasiyumu nkibikoresho byoherejwe na proton, nibindi. Byongeye kandi, ukurikije ubushyuhe bwakazi, selile zishobora kugabanywamo selile yubushyuhe bwinshi nubushyuhe buke selile ya lisansi, iyambere irimo cyane cyane selile ya lisansi ikomeye (SOFC) hamwe na selile ya karubone yashongeshejwe (MCFC), Iyanyuma irimo proton yo guhanahana amavuta ya selile (PEMFC), selile methanol itaziguye (DMFC), selile ya alkaline (AFC), selile ya fosifori ya selile (PAFC), nibindi

Guhindura protonselile ya lisansi (PEMFC) ikoresha amazi ashingiye kuri acide polymer membrane nka electrolytite zabo. Ingirabuzimafatizo za PEMFC zigomba gukora munsi ya gaze ya hydrogène nziza kubera ubushyuhe buke bwo gukora (munsi ya 100 ° C) no gukoresha electrode nziza yicyuma (electrode ishingiye kuri platine). Ugereranije nizindi selile, PEMFC ifite ibyiza byubushyuhe buke bwo gukora, umuvuduko wo gutangira byihuse, ubwinshi bwingufu nyinshi, electrolyte idashobora kwangirika nubuzima bwa serivisi ndende. Kubwibyo, byahindutse tekinoroji yingenzi ikoreshwa mubinyabiziga bitwara lisansi, ariko kandi ikoreshwa mubice bigendanwa kandi bihagaze. Nk’uko E4 Tech ibigaragaza, biteganijwe ko ibicuruzwa byoherejwe na peteroli ya PEMFC bigera kuri 44.100 muri 2019, bingana na 62% by’umugabane w’isi; Biteganijwe ko ubushobozi bwashyizweho bugera kuri 934.2MW, bingana na 83% byisi yose.

Ingirabuzimafatizo zikoresha amashanyarazi kugirango zihindure ingufu za chimique ziva kuri lisansi (hydrogène) kuri anode na okiside (ogisijeni) kuri cathode mumashanyarazi kugirango ikinyabiziga cyose. By'umwihariko, ibice by'ibanze bigize selile zirimo sisitemu ya moteri, amashanyarazi afasha na moteri; Muri byo, sisitemu ya moteri ikubiyemo ahanini moteri igizwe na reaction yumuriro, sisitemu yo kubika hydrogène yimodoka, sisitemu yo gukonjesha hamwe na DCDC ya voltage ihindura. Imashini nicyo kintu gikomeye cyane. Nahantu hydrogène na ogisijeni bigira. Igizwe ningirabuzimafatizo nyinshi zegeranye hamwe, kandi ibikoresho byingenzi birimo bipolar plate, membrane electrode, plaque ya nyuma nibindi.
