Ọganihu nke teknụzụ mmepụta hydrogen na nyocha akụ na ụba - Mmepụta hydrogen na mkpụrụ ndụ alkaline electrolytic

Mmepụta hydrogen nke mkpụrụ ndụ alkaline bụ teknụzụ mmepụta hydrogen electrolytic tozuru oke. Mkpụrụ ndụ alkaline dị nchebe ma bụrụ nke a pụrụ ịtụkwasị obi, na-adịru afọ 15, a na-ejikwa ya nke ukwuu n'ahịa. Ọrụ nke mkpụrụ ndụ alkaline na-arụkarị bụ 42% ~ 78%. N'ime afọ ole na ole gara aga, mkpụrụ ndụ alkaline electrolytic enweela ọganihu n'akụkụ abụọ bụ isi. N'otu aka, arụ ọrụ nke mkpụrụ ndụ ka mma emeela ka ọ dịkwuo mma ma belata ọnụ ahịa ọrụ nke metụtara oriri ọkụ eletrik. N'aka nke ọzọ, njupụta ọkụ eletrik na-abawanye ma ọnụ ahịa itinye ego na-ebelata.

E gosiri ụkpụrụ ọrụ nke alkaline electrolyzer n'ihe osise a. Batrị ahụ nwere electrodes abụọ nke diaphragm ikuku na-anaghị ekwe ka ikuku kewapụ. A na-etinye mgbakọ batrị n'ime nnukwu njupụta 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 a naghị eji ha eme ihe n'ọtụtụ oge. Isi ihe na-adịghị mma nke electrolytes bụ na ha na-emebi emebi. Cell ahụ na-arụ ọrụ na okpomọkụ nke 65 °C ruo 100 °C. Kathode nke sel ahụ na-emepụta hydrogen, OH nke na-esi na ya apụta - na-agafe na diaphragm gaa na anode, ebe ọ na-ejikọtaghachi iji mepụta oxygen.

Mkpụrụ ndụ elektrolytic alkaline dị elu dabara adaba maka mmepụta hydrogen buru ibu. Mkpụrụ ndụ elektrolytic alkaline nke ụfọdụ ndị nrụpụta mepụtara nwere ikike mmepụta hydrogen dị elu na (500 ~ 760Nm3/h), yana oriri ike kwekọrọ na ya nke 2150 ~ 3534kW. N'ọrụ, iji gbochie imepụta ngwakọta gas na-ere ọkụ, a na-ebelata mmepụta hydrogen na 25% ruo 100% nke oke ọkwa, njupụta ugbu a kachasị ekwe omume bụ ihe dị ka 0.4A/cm2, okpomọkụ ọrụ bụ 5 ruo 100°C, nrụgide electrolytic kachasị dịkwa nso na 2.5 ruo 3.0 MPa. Mgbe nrụgide electrolytic dị oke elu, ọnụ ahịa itinye ego na-abawanye ma ihe egwu nke ngwakọta gas na-emerụ ahụ na-abawanye nke ukwuu. Na-enweghị ngwaọrụ nhicha enyemaka ọ bụla, ịdị ọcha nke hydrogen nke elektrolytic cell alkaline mepụtara nwere ike iru 99%. Mmiri elektrolytic cell alkaline ga-adị ọcha, iji chebe elektrodi ahụ na ọrụ nchekwa, njikwa mmiri erughị 5S/cm.
