Iterambere ry'ikoranabuhanga mu gukora imashini ya hydrogen n'isesengura ry'ubukungu - Ikorwa rya hydrogen mu turemangingo twa electrolytic ya alkaline

Gutunganya hydrogen ya selile za alkali ni ikoranabuhanga rigezweho ryo gukora hydrogen ya electrolytic. Selile za alkali ni nziza kandi zizewe, zimara igihe cy'imyaka 15, kandi zakoreshejwe cyane mu bucuruzi. Imikorere myiza ya selile za alkali muri rusange ni 42% ~ 78%. Mu myaka mike ishize, selile za alkali za electrolytic zateye imbere mu ngingo ebyiri z'ingenzi. Ku ruhande rumwe, imikorere myiza ya selile yarushijeho kuba myiza kandi ikiguzi cy'imikorere kijyanye n'ikoreshwa ry'amashanyarazi cyaragabanutse. Ku rundi ruhande, ubucucike bw'amashanyarazi mu mikorere buriyongera kandi ikiguzi cy'ishoramari kiragabanuka.

Ihame ry'imikorere ya electrolyzer ya alkaline rigaragara ku ishusho. Bateri igizwe na electrodes ebyiri zitandukanyijwe na diaphragm idahumeka. Guteranya bateri byinjizwa mu gipimo kinini cya electrolyte y'amazi ya alkaline KOH (20% kugeza 30%) kugira ngo byongere imikorere ya ionic. Ibisubizo bya NaOH na NaCl nabyo bishobora gukoreshwa nk'electrolytes, ariko ntibikunze gukoreshwa. Ingorane nyamukuru ya electrolytes ni uko zitera kwangirika. Seli ikora ku bushyuhe bwa 65 °C kugeza 100 °C. Cathode y'seli ikora hydrogen, naho OH ivamo - inyura muri diaphragm ijya kuri anode, aho yongera kwihuza kugira ngo ikore ogisijeni.

Uturemangingo tw’amashanyarazi twa alkaline duteye imbere turakwiriye gukorwa mu buryo bunini bwa hydrogen. Uturemangingo tw’amashanyarazi twa alkaline twakozwe n’inganda zimwe na zimwe dufite ubushobozi bwo gukora hydrogen bwinshi cyane kuri (500 ~ 760Nm3/h), hamwe n’ingufu zikoreshwa 2150 ~ 3534kW. Mu by’ukuri, kugira ngo hirindwe ko habaho uruvange rw’umwuka ushobora gushya, umusaruro wa hydrogen ugarukira kuri 25% kugeza 100% by’urugero rw’ifatizo, ubucucike bw’amashanyarazi bwemewe ni hafi 0.4A/cm2, ubushyuhe bwo gukora ni 5 kugeza 100°C, kandi umuvuduko ntarengwa wa electrolytic uba uri hagati ya 2.5 na 3.0 MPa. Iyo umuvuduko wa electrolytic uri hejuru cyane, ikiguzi cy’ishoramari kiriyongera kandi ibyago byo kurema uruvange rwa gazi mbi biriyongera cyane. Hatabayeho igikoresho cy’inyongera cyo gusukura, ubuziranenge bwa hydrogen bukorwa na electrolysis y’uturemangingo twa alkaline bushobora kugera kuri 99%. Amazi ya electrolytic y’uturemangingo twa alkaline agomba kuba meza, kugira ngo arinde electrode kandi ikore neza, imikorere y’amazi iba iri munsi ya 5S/cm2.
