Imveliso ye-alkaline ye-hydrogen ye-alkaline yitekhnoloji yokuvelisa i-hydrogen esele ikhulile ngokwentelekiso. Iseli yealkaline ikhuselekile kwaye inokwethenjelwa, iphila iminyaka eyi-15, kwaye isetyenziswa ngokubanzi kurhwebo. Ukusebenza kakuhle kweseli yealkaline ngokuqhelekileyo kungama-42% ~ 78%. Kwiminyaka embalwa edlulileyo, iiseli ze-alkaline electrolytic zenze inkqubela kwizinto ezimbini eziphambili. Kwelinye icala, ukusebenza kakuhle kweeseli kuphuculwe kwaye iindleko zokusebenza ezinxulumene nokusetyenziswa kombane ziye zancitshiswa. Ngakolunye uhlangothi, ukuxinana kwangoku kokusebenza kuyenyuka kwaye iindleko zotyalo-mali ziyancipha.
Umgaqo osebenzayo we-alkaline electrolyzer uboniswe kumzobo. Ibhetri inee-electrode ezimbini ezahlulwe yi-diaphragm eqinile emoyeni. Idibaniso yebhetri intywiliselwa kuxinaniso oluphezulu lwealkaline ye-electrolyte ye-alkaline KOH (20% ukuya kwi-30%) ukunyusa ukuhanjiswa kwe-ionic. Izisombululo ze-NaOH kunye ne-NaCl nazo zingasetyenziswa njenge-electrolytes, kodwa aziqhelekanga ukusetyenziswa. Eyona nto ingalunganga ye-electrolytes kukuba i-corrosion. Iseli isebenza kubushushu obungama-65 °C ukuya kwi-100°C. I-cathode yeseli ivelisa i-hydrogen, kwaye i-OH ephumela - ihamba nge-diaphragm ukuya kwi-anode, apho iphinda idibanise ukuvelisa i-oksijini.
Iiseli ze-alkaline ze-electrolytic eziphezulu zifanelekile kwimveliso ye-hydrogen enkulu. Iiseli ze-alkaline ze-electrolytic ezenziwe ngabanye abavelisi banomthamo ophezulu kakhulu we-hydrogen wokuvelisa kwi-(500 ~ 760Nm3 / h), kunye nokusetyenziswa kwamandla ahambelanayo we-2150 ~ 3534kW. Ngokwenza, ukuthintela ukudalwa kwemixube yegesi enokutsha, isivuno se-hydrogen sikhawulelwe kwi-25% ukuya kwi-100% yoluhlu olulinganisiweyo, ubuninzi obuvumelekileyo obukhoyo bumalunga ne-0.4A / cm2, ukushisa okusebenzayo ngu-5 ukuya kwi-100 ° C, kunye noxinzelelo oluphezulu lwe-electrolytic lusondele kwi-2.5 ukuya kwi-3.0 MPa. Xa uxinzelelo lwe-electrolytic luphezulu kakhulu, iindleko zotyalo-mali zinyuka kwaye umngcipheko wokwakheka komxube wegesi onobungozi uyanda kakhulu. Ngaphandle kwesixhobo esincedisayo sokucoca, ukucoceka kwe-hydrogen eveliswa yi-alkaline cell electrolysis kunokufikelela kwi-99%. I-alkaline electrolytic cell electrolytic amanzi kufuneka abe msulwa, ukwenzela ukukhusela i-electrode kunye nokusebenza okukhuselekileyo, ukuhanjiswa kwamanzi kungaphantsi kwe-5S / cm.
