ʻO ka holomua o ka ʻenehana hana hydrogen a me ka nānā ʻana i ka hoʻokele waiwai - ʻO ka hana hydrogen i loko o ka cell electrolytic alkaline

ʻO ka hana ʻana o ka hydrogen cell alkaline kahi ʻenehana hana electrolytic hydrogen ʻoi loa. He palekana a hilinaʻi ʻia ka cell alkaline, me ke ola o 15 mau makahiki, a ua hoʻohana nui ʻia ma ke kālepa. ʻO ka hana kūpono o ka cell alkaline he 42% ~ 78%. I nā makahiki i hala iho nei, ua holomua nā cell electrolytic alkaline i ʻelua mau mea nui. Ma kekahi ʻaoʻao, ua hoʻomaikaʻi ʻia ka hoʻomaikaʻi ʻana o ka cell phone a ua hoʻemi ʻia nā kumukūʻai hana e pili ana i ka hoʻohana uila. Ma ka ʻaoʻao ʻē aʻe, piʻi ka nui o ka hana o kēia manawa a ke emi nei ke kumukūʻai kālā.

Hōʻike ʻia ke kumu hana o ka electrolyzer alkaline ma ke kiʻi. Aia ka pākaukau i ʻelua electrodes i hoʻokaʻawale ʻia e kahi diaphragm paʻa ea. Hoʻokomo ʻia ka hui ʻana o ka pākaukau i kahi kiʻekiʻe o ka alkaline wai electrolyte KOH (20% a 30%) e hoʻonui i ka conductivity ionic. Hiki ke hoʻohana ʻia nā hopena NaOH a me NaCl e like me nā electrolytes, akā ʻaʻole hoʻohana mau ʻia. ʻO ka hemahema nui o nā electrolytes ʻo ia ka corrosive. Ke hana nei ke kelepona ma kahi mahana o 65 °C a i 100 °C. Hoʻopuka ka cathode o ke kelepona i ka hydrogen, a ʻo ka hopena OH - kahe i ka diaphragm i ka anode, kahi e hui hou ai e hana i ka oxygen.

He kūpono nā keena electrolytic alkaline kiʻekiʻe no ka hana hydrogen nui. ʻO nā kinikini electrolytic alkaline i hana ʻia e kekahi mau mea hana he kiʻekiʻe loa ka mana hana hydrogen ma (500 ~ 760Nm3/h), me ka hoʻohana ʻana i ka mana o 2150 ~ 3534kW. I ka hoʻomaʻamaʻa, i mea e pale ai i ka hana ʻana o nā hui ʻana o ke kinoea, ua kaupalena ʻia ka hua hydrogen i 25% a 100% o ka pae helu ʻia, ʻo ka nui o ka nui o kēia manawa e pili ana i 0.4A / cm2, ʻo ka mahana hana he 5 a 100 ° C, a ʻo ke kaomi electrolytic kiʻekiʻe kokoke i 2.5 a 3.0 MPa. Ke kiʻekiʻe loa ke kaomi electrolytic, piʻi ke kumukūʻai hoʻopukapuka a piʻi nui ka hoʻokumu ʻana o ka hui kino kino. Me ka ʻole o kahi mea hoʻomaʻemaʻe kōkua, hiki i ka maʻemaʻe o ka hydrogen i hana ʻia e ka electrolysis cell alkaline hiki ke hiki i 99%. Pono e maʻemaʻe ka wai electrolytic cell alkaline, i mea e pale ai i ka electrode a me ka hana palekana, ʻoi aku ka emi o ka conductivity wai ma mua o 5S / cm.
