ʻO ka hana ʻana o ka hydrogen cell alkaline he ʻenehana hana hydrogen electrolytic i ʻoi aku ka maikaʻi. Palekana a hilinaʻi hoʻi ke kelepona alkaline, me ke ola he 15 mau makahiki, a ua hoʻohana nui ʻia ma ke kālepa. ʻO ka pono hana o ke kelepona alkaline maʻamau he 42% ~ 78%. I nā makahiki i hala iho nei, ua holomua nā kelepona electrolytic alkaline ma nā ʻano nui ʻelua. Ma kekahi ʻaoʻao, ua hoʻomaikaʻi ʻia ka pono o ke kelepona i hoʻomaikaʻi ʻia a ua hoʻemi ʻia nā kumukūʻai hana e pili ana i ka hoʻohana ʻana i ka uila. Ma kekahi ʻaoʻao, piʻi ka nui o ke au hana a emi ke kumukūʻai hoʻopukapuka kālā.
Ua hōʻike ʻia ke kumumanaʻo hana o ka electrolyzer alkaline ma ke kiʻi. Aia ka pākahiko i ʻelua mau electrodes i hoʻokaʻawale ʻia e kahi diaphragm paʻa ea. Hoʻokomo ʻia ka ʻākoakoa pākahiko i loko o kahi electrolyte wai alkaline kiʻekiʻe KOH (20% a 30%) e hoʻonui i ka conductivity ionic. Hiki ke hoʻohana ʻia nā hopena NaOH a me NaCl ma ke ʻano he electrolytes, akā ʻaʻole lākou i hoʻohana pinepine ʻia. ʻO ka hemahema nui o nā electrolytes, ʻo ia ka corrosive. Hana ka cell ma kahi mahana o 65 °C a 100 °C. Hoʻopuka ka cathode o ke kelepona i ka hydrogen, a ʻo ka hopena OH - e kahe ana ma o ka diaphragm i ka anode, kahi e hui hou ai e hana i ka oxygen.
He kūpono nā cell electrolytic alkaline holomua no ka hana hydrogen nui. Loaʻa i nā cell electrolytic alkaline i hana ʻia e kekahi mau mea hana ka mana hana hydrogen kiʻekiʻe loa ma (500 ~ 760Nm3/h), me ka hoʻohana ʻana i ka mana like o 2150 ~ 3534kW. I ka hana maoli, no ka pale ʻana i ka hana ʻana o nā hui kinoea lapalapa, ua kaupalena ʻia ka hua hydrogen i 25% a 100% o ka pae i helu ʻia, ʻo ka nui o ke au i ʻae ʻia ma kahi o 0.4A/cm2, ʻo ka mahana hana he 5 a 100°C, a ʻo ke kaomi electrolytic kiʻekiʻe loa kokoke i 2.5 a 3.0 MPa. Ke kiʻekiʻe loa ke kaomi electrolytic, piʻi ke kumukūʻai hoʻopukapuka kālā a piʻi nui ka pilikia o ka hoʻokumu ʻana i ka hui kinoea ʻino. Me ka ʻole o kekahi mea hoʻomaʻemaʻe kōkua, hiki i ka maʻemaʻe o ka hydrogen i hana ʻia e ka electrolysis cell alkaline ke hiki i ka 99%. Pono ka wai electrolytic cell electrolytic alkaline e maʻemaʻe, i mea e pale ai i ka electrode a me ka hana palekana, ʻoi aku ka liʻiliʻi o ka conductivity wai ma mua o 5S/cm.
