Imveliso yehydrogen yeeseli ze-alkaline yiteknoloji yokuvelisa ihydrogen ye-electrolytic evuthiweyo. Iseli ye-alkaline ikhuselekile kwaye ithembekile, inobomi beminyaka eli-15, kwaye isetyenziswa kakhulu kwezorhwebo. Ukusebenza kakuhle kweseli ye-alkaline ngokubanzi yi-42% ~ 78%. Kwiminyaka embalwa edlulileyo, iiseli ze-alkaline electrolytic ziye zenza inkqubela phambili kwiinkalo ezimbini eziphambili. Kwelinye icala, ukusebenza kakuhle kweeseli kuphuculwe kwaye iindleko zokusebenza ezinxulumene nokusetyenziswa kombane zinciphile. Kwelinye icala, uxinano lwangoku lokusebenza luyanda kwaye iindleko zotyalo-mali ziyancipha.
Umgaqo osebenzayo we-alkaline electrolyzer uboniswe kumfanekiso. Ibhetri inee-electrode ezimbini ezahlulwe yi-diaphragm engangeni moya. Ukuhlanganiswa kwebhetri kuntywiliselwa kuxinzelelo oluphezulu lwe-alkaline liquid electrolyte KOH (20% ukuya kwi-30%) ukuze kuphuculwe i-ionic conductivity. Izisombululo ze-NaOH kunye ne-NaCl nazo zingasetyenziswa njengee-electrolytes, kodwa azisetyenziswa rhoqo. Eyona ngxaki iphambili yee-electrolytes kukuba ziyabola. Iseli isebenza kubushushu obuphakathi kwe-65 °C ukuya kwi-100 °C. I-cathode yeseli ivelisa i-hydrogen, kwaye i-OH ephumayo - idlula kwi-diaphragm iye kwi-anode, apho iphinda ihlangane khona ukuze ivelise i-oxygen.
Iiseli ze-alkaline electrolytic eziphambili zifanelekile kwimveliso enkulu ye-hydrogen. Iiseli ze-alkaline electrolytic ezenziwe ngabanye abavelisi zinamandla aphezulu kakhulu emveliso ye-hydrogen kwi (500 ~ 760Nm3/h), kunye nokusetyenziswa kwamandla okuhambelanayo kwe-2150 ~ 3534kW. Ngokwesiqhelo, ukuthintela ukudalwa kwemixube yegesi evuthayo, isivuno se-hydrogen sinqunyelwe kwi-25% ukuya kwi-100% yoluhlu olulinganisiweyo, ubuninzi boxinzelelo lwangoku oluvumelekileyo malunga ne-0.4A/cm2, ubushushu bokusebenza buyi-5 ukuya kwi-100°C, kwaye uxinzelelo oluphezulu lwe-electrolytic lusondele kwi-2.5 ukuya kwi-3.0 MPa. Xa uxinzelelo lwe-electrolytic luphezulu kakhulu, iindleko zotyalo-mali ziyanda kwaye umngcipheko wokwakheka komxube wegesi onobungozi uyanda kakhulu. Ngaphandle kwesixhobo sokucoca esincedisayo, ubumsulwa be-hydrogen obuveliswa yi-alkaline cell electrolysis bunokufikelela kwi-99%. Amanzi e-alkaline electrolytic cell electrolytic kufuneka abe msulwa, ukuze kukhuselwe i-electrode kunye nokusebenza ngokukhuselekileyo, ukuhanjiswa kwamanzi kungaphantsi kwe-5S/cm2.
