Ci gaban fasahar samar da hydrogen da nazarin tattalin arziki - samar da hydrogen a cikin kwayar halitta ta alkaline

Samar da hydrogen cell Alkaline fasaha ce ta samar da hydrogen da balagagge balagagge. Tantanin alkaline yana da aminci kuma abin dogaro, yana da tsawon rayuwa na shekaru 15, kuma ana amfani da shi sosai a kasuwa. Aiki yadda ya dace na alkaline cell shine gabaɗaya 42% ~ 78%. A cikin 'yan shekarun da suka gabata, kwayoyin halitta na alkaline electrolytic sun sami ci gaba ta hanyoyi biyu. A gefe guda, an inganta ingantaccen aikin tantanin halitta kuma an rage farashin aiki da ke tattare da amfani da wutar lantarki. A gefe guda, yawan aiki na yanzu yana ƙaruwa kuma farashin saka hannun jari yana raguwa.

An nuna ka'idar aiki na alkaline electrolyzer a cikin adadi. Baturin ya ƙunshi na'urorin lantarki guda biyu waɗanda ke raba su da diaphragm mai ɗaukar iska. An nutsar da taron baturi a cikin babban taro na alkaline ruwa electrolyte KOH (20% zuwa 30%) don haɓaka haɓakar ionic. Ana iya amfani da mafita na NaOH da NaCl azaman electrolytes, amma ba a saba amfani da su ba. Babban hasara na electrolytes shine cewa suna da lalata. Tantanin halitta yana aiki a zafin jiki na 65 ° C zuwa 100 ° C. Cathode na tantanin halitta yana samar da hydrogen, kuma sakamakon OH - yana gudana ta cikin diaphragm zuwa anode, inda ya sake haɗuwa don samar da oxygen.

Advanced alkaline electrolytic Kwayoyin sun dace da manyan sikelin hydrogen samar. Kwayoyin alkaline electrolytic da wasu masana'antun suka yi suna da ƙarfin samar da hydrogen sosai a (500 ~ 760Nm3/h), tare da daidaitaccen ƙarfin 2150 ~ 3534kW. A aikace, don hana ƙirƙirar gaurayawan gas mai ƙonewa, yawan amfanin hydrogen yana iyakance zuwa 25% zuwa 100% na kewayon da aka ƙididdigewa, matsakaicin ƙyalli na yanzu yana kusan 0.4A/cm2, zafin aiki shine 5 zuwa 100 ° C, kuma matsakaicin matsa lamba na electrolytic yana kusa da 2.5 zuwa 3.0 MPa. Lokacin da matsa lamba na electrolytic ya yi yawa, farashin saka hannun jari yana ƙaruwa kuma haɗarin samuwar cakuda gas mai cutarwa yana ƙaruwa sosai. Ba tare da kowane na'ura mai tsarkakewa ba, tsabtar hydrogen da aka samar ta hanyar electrolysis cell alkaline zai iya kaiwa 99%. Alkaline electrolytic cell electrolytic ruwa dole ne ya kasance mai tsabta, don kare wutar lantarki da kuma aiki mai lafiya, rashin ruwa bai wuce 5S / cm ba.
