Iterambere rya tekinoroji ya hydrogène nisesengura ryubukungu - Umusaruro wa hydrogène muri selile ya electrolytike ya alkaline

Umusemburo wa hydrogène ya alkaline ni tekinoroji ikuze ya electrolytike ikora. Alkaline selile ifite umutekano kandi yizewe, hamwe nubuzima bwimyaka 15, kandi yakoreshejwe mubucuruzi. Imikorere ikora ya alkaline selile ni 42% ~ 78%. Mu myaka mike ishize, selile ya electrolytike ya alkaline yateye imbere mubice bibiri byingenzi. Ku ruhande rumwe, imikorere myiza ya selile yaratejwe imbere kandi amafaranga yo gukora ajyanye no gukoresha amashanyarazi yagabanutse. Kurundi ruhande, ibikorwa byubu bigenda byiyongera kandi igiciro cyishoramari kigabanuka.

Ihame ryakazi rya alkaline electrolyzer irerekanwa mumashusho. Batare igizwe na electrode ebyiri zitandukanijwe na diaphragm ifata ikirere. Iteraniro rya bateri ryinjijwe cyane murwego rwa alkaline yamazi ya electrolyte KOH (20% kugeza 30%) kugirango ionic itwarwe neza. Ibisubizo bya NaOH na NaCl birashobora kandi gukoreshwa nka electrolytite, ariko ntibisanzwe bikoreshwa. Ingaruka nyamukuru ya electrolytite nuko yangirika. Ingirabuzimafatizo ikora ku bushyuhe bwa 65 ° C kugeza 100 ° C. Cathode ya selile itanga hydrogène, hanyuma OH ikavamo - ikanyura muri diafragma ikagera kuri anode, aho yisubiraho kugirango ikore ogisijeni.

Utugingo ngengabuzima twitwa alkaline electrolytike dukwiranye n’umusaruro munini wa hydrogène. Alkaline electrolytike selile yakozwe nababikora bamwe bafite ubushobozi bwo kubyara hydrogène cyane kuri (500 ~ 760Nm3 / h), hamwe ningufu zingana na 2150 ~ 3534kW. Mubikorwa, kugirango hirindwe ko havangwa imvange ya gaz yaka, umusaruro wa hydrogène ugarukira kuri 25% kugeza 100% byurwego rwagenwe, ubwinshi bwokwemerera ubu ni hafi 0.4A / cm2, ubushyuhe bwo gukora ni 5 kugeza 100 ° C, n'umuvuduko ntarengwa wa electrolytike uri hafi ya MPa 2.5 kugeza 3.0. Iyo umuvuduko wa electrolytike ari mwinshi, igiciro cyishoramari kiriyongera kandi ibyago byo gushiraho imvange ya gaze yangiza byiyongera cyane. Hatariho igikoresho cyo kweza gifasha, ubuziranenge bwa hydrogène ikorwa na alkaline selile electrolysis irashobora kugera kuri 99%. Amazi ya alkaline electrolytike selile electrolytique amazi agomba kuba meza, kugirango arinde electrode kandi ikore neza, imiyoboro y'amazi iri munsi ya 5S / cm.
