1. Hydrogen ntau lawm los ntawm alkaline electrolysis ntawm dej
Lub diaphragm ntawm cov dej electrolytic hydrogen ntau lawm tank yog tsim los ntawm cov ntaub ntawv uas tsis yog asbestos thiab plays lub luag hauj lwm ntawm kev sib cais roj. Cov electrolyte ntawm industrial alkaline dej electrolyzers feem ntau siv cov tshuaj potassium hydroxide nrog ib feem ntawm 20% mus rau 30%. Kev khiav hauj lwm kub ntawm lub electrolyzer yog 70 mus rau 80 degree, kev khiav hauj lwm tam sim no ceev yog hais txog 0.25 amperes / cm2, thiab cov roj siab generated yog 0.1 ~ 1.6 MPa, tag nrho efficiency yog 62% ~ 82%. Alkaline dej hydrogen ntau lawm yog ib tug paub tab technology nrog tsawg peev thiab kev khiav hauj lwm nqi, tab sis muaj teeb meem xws li alkali poob, corrosion, thiab siab zog noj.
2. Dej ntshiab electrolysis los tsim hydrogen
Sib txawv ntawm cov dej electrolysis ntawm hydrogen ntau lawm, proton exchange membrane (PEM) electrolysis ntawm cov dej rau hydrogen ntau lawm siv ib tug perfluorosulfonic acid proton exchange membrane nrog zoo tshuaj stability, proton conductivity thiab roj sib cais es tsis txhob ntawm ib tug non-asbestos separator raws li cov khoom. electrolyte, uas tuaj yeem tiv thaiv kev hloov hluav taws xob zoo los txhim kho kev nyab xeeb ntawm cov hlwb electrolytic.
3. Hydrogen ntau lawm los ntawm high-temperature khoom oxide electrolysis ntawm dej
High-temperature solid oxide dej electrolysis rau hydrogen ntau lawm txawv ntawm alkaline dej electrolysis thiab PEM dej electrolysis. High-temperature solid oxide dej electrolysis rau hydrogen ntau lawm siv cov khoom oxide raws li cov khoom siv electrolyte. Kev khiav hauj lwm kub yog 800 ~ 1000. Lub electrochemical kev ua tau zoo ntawm cov txheej txheem hydrogen ntau lawm Qhov tseem ceeb txhim kho efficiency.
