Lub peev xwm ntawm hydrogen ua lub zog huv si tau txais kev lees paub thoob ntiaj teb, thiab Tuam Tshoj tab tom ua qhov zoo tshaj plaws hauv daim teb no. Thaum electrolyzing dej nrog lub zog tauj dua tshiab tau ua cov xov xwm, Suav cov kws tshawb fawb tau coj nws ib kauj ruam ntxiv los ntawm kev ncaj qha electrolyzing dej hiav txwv, ib qho kev tsim kho tshiab.
Coj los ntawm tus kws tshawb fawb Wang Erdong los ntawm Dalian Institute of Chemical Physics, ib ceg ntawm Suav Academy ntawm Kev Tshawb Fawb, pab pawg tsis ntev los no tau tshaj tawm qhov kev ua tiav loj: ntau dua 2000 teev sib law liag ntawm cov khoom siv hydrogen ruaj khov los ntawm dej hiav txwv. Dab tsi ua rau lawv lub cev sib nrug tsis yog tsuas yog nws cov txiaj ntsig tab sis kuj tseem ua rau nws lub zog ua tau zoo, nrog rau qhov nruab nrab DC fais fab noj tsuas yog 4.04 kWh ib cubic meter ntawm hydrogen.
Direct electrolysis ntawm seawater yuav suab yooj yim, tab sis nws ua rau muaj teeb meem loj. Lub hiav txwv yog ib tug complex sib tov ntawm ntau yam ionic ntsiab, xws li chloride, magnesium, thiab calcium ions. Cov ions no tau paub tias ua rau muaj kev cuam tshuam tsis zoo, ua rau muaj teeb meem xws li chlorine nag lossis daus thiab cov khoom siv corrosion, uas cuam tshuam rau kev ntseeg siab thiab kev ua haujlwm ntawm cov txheej txheem.
Txhawm rau kov yeej cov teeb meem no, pab pawg tau siv txoj hauv kev zoo. Lawv tau tshawb fawb ntau, tsim cov ntaub ntawv tshwj xeeb, thiab tsim cov tshuab ua ke. Lawv cov kev siv zog tau tsom mus rau kev txhim kho catalyst, cov tshuaj tiv thaiv electrode, thiab kev tswj cov electrolyte.
Lawv cov kev ua tiav suav nrog kev tsim cov tshuaj chlorine-resistant electrodes rau oxygen evolution, electrodes uas tiv thaiv calcium thiab magnesium ion deposition thaum hydrogen evolution, ib tug heev npaum electrolyzer tsim tailored rau seawater, thiab automated tswj technology rau electrolyte concentration. Cov kev tsim kho tshiab no tsis yog theoretical xwb; pab neeg no tau ua ntawv thov 17 daim ntawv thov patent cuam tshuam nrog seawater electrolysis, tsim kom muaj cov cuab yeej cuab tam muaj zog.
Qhov kev ua tau zoo ntawm lawv 1 cubic meter ib teev seawater electrolysis chav tsev yog qhov tshwj xeeb tshaj plaws. Siv cov dej hiav txwv ntuj los ntawm Hiav Txwv Dalian, chav tsev tau nthuav tawm cov txiaj ntsig zoo thaum nws 2000- teev kev sim khiav: qhov nruab nrab chamber voltage ntawm 1.69V, lub zog ua haujlwm ntawm 4.04 kWh ib cubic meter ntawm hydrogen, thiab cov ntsiab lus oxygen chlorine tsawg dua. ntau tshaj 20 feem ntawm ib billion.
Tsav los ntawm lawv txoj kev xav, Wang Erdong thiab nws pab neeg tau ua haujlwm rau qhov kev ua haujlwm tom ntej, txhawm rau ua ob npaug ntawm qhov tam sim no ntom ntom ntawm cov electrolyzer nyob rau hauv tib qhov voltage, ntxiv dag zog rau nws cov efficiency.
