Mmepụta hydrogen cell alkaline bụ teknụzụ mmepụta hydrogen tozuru oke. Mkpụrụ ndụ alkaline dị nchebe ma bụrụ ndị a pụrụ ịdabere na ya, na-enwe ogologo ndụ nke afọ 15, ma ejiriwo ya mee ihe n'ọtụtụ ebe azụmahịa. Na-arụ ọrụ arụmọrụ nke alkaline cell bụ n'ozuzu 42% ~ 78%. N'ime afọ ole na ole gara aga, mkpụrụ ndụ electrolytic alkaline enweela ọganihu n'akụkụ abụọ. N'otu aka ahụ, a na-emeziwanye arụmọrụ cell na-emeziwanye ma na-ebelata ụgwọ ọrụ nke metụtara oriri ọkụ eletrik. N'aka nke ọzọ, njupụta na-arụ ọrụ ugbu a na-abawanye na ego ntinye ego na-ebelata.
E gosipụtara ụkpụrụ ọrụ nke alkaline electrolyzer na foto a. Batrị ahụ nwere electrodes abụọ kewapụrụ site na diaphragm na-ekpochi ikuku. A na-emikpu mgbakọ batrị n'ime nnukwu ntinye nke alkaline liquid electrolyte KOH (20% ruo 30%) iji mee ka ionic conductivity dịkwuo elu. Enwere ike iji ngwọta NaOH na NaCl dị ka electrolytes, mana anaghị ejikarị ha eme ihe. Isi mwepu nke electrolytes bụ na ha na-emebi emebi. Igwe ahụ na-arụ ọrụ na okpomọkụ nke 65 °C ruo 100 Celsius. Cathode nke cell na-emepụta hydrogen, na OH na-esi na ya pụta - na-agafe na diaphragm na anode, ebe ọ na-ejikọta ya na-emepụta oxygen.
Mkpụrụ ndụ electrolytic alkaline dị elu dabara adaba maka mmepụta hydrogen buru ibu. Mkpụrụ ndụ alkaline electrolytic mere nke ụfọdụ ndị na-emepụta nwere ikike mmepụta hydrogen dị elu na (500 ~ 760Nm3 / h), yana oriri ike kwekọrọ na 2150 ~ 3534kW. Na omume, iji gbochie mmepụta nke ngwakọta gas na-ere ọkụ, mkpụrụ hydrogen na-ejedebe na 25% ruo 100% nke ọnụọgụgụ, oke ikike ugbu a bụ ihe dịka 0.4A / cm2, okpomọkụ na-arụ ọrụ bụ 5 ruo 100 ° C, na nrụgide electrolytic kachasị dị nso na 2.5 ruo 3.0 MPa. Mgbe nrụgide electrolytic dị oke elu, ego ntinye ego na-abawanye na ihe ize ndụ nke ịmepụta ngwakọta gas na-emerụ ahụ na-abawanye nke ukwuu. Na-enweghị ngwaọrụ nhicha enyemaka ọ bụla, ịdị ọcha nke hydrogen nke electrolysis cell alkaline mepụtara nwere ike iru 99%. Alkaline electrolytic cell electrolytic mmiri ga-adị ọcha, iji chebe electrode na nchekwa ọrụ, mmiri conductivity bụ ihe na-erughị 5S / cm.
