Titanium muaj kev pom zoo, cov ntaub ntawv muaj ntau, thiab cov khoom siv hluav taws xob zoo li cov khoom siv hluav taws xob zoo li cov khoom siv hluav taws xob zoo li lub luag haujlwm nyob rau hauv electrolyzer .
Cov hauv paus ntsiab lus ntawm titanium muaj nyob rau hauv electrolyzers
Electroolyzers siv cov txheej txheem electrochemical los cais dej (h2o) rau hauv hydrogen (h₂) thiab cov pa oxy} {1} {1} {1}
Cov qauv sib tw
Titanium muaj kev cuam tshuam lub network ntawm kev cuam tshuam cov fibers tsim cov cheeb tsam qib siab av rau:
Roj diffusion: kev thauj khoom ntawm H₂ thiab O₂ ntawm cov chaw tiv thaiv .
Ua kua rau: cov kev faib tawm cov khoom siv hluav taws xob (e {{{}}}}}}}}
Cov qauv no tiv thaiv cov roj npuas los ntawm txhaws cov electrode, kom ntseeg tsis tau kev cuam tshuam tsis cuam tshuam .
Hluav Taws Xob Kev Tshaj Tawm
Sai hluav taws xob hluav taws xob thauj khoom ntawm txheej catalyst thiab cov neeg sau ntawv tam sim no tau ua tau los ntawm Titanium qhov qis tsis kam tiv {}}
Qhov no txo qis zog poob thiab txhim kho electrolyzer efficiency .
Electrochemical kev ruaj khov
Titanium foos ib txheej oxide coxide (ti₂) hauv kev tiv thaiv kev xeb, tiv thaiv nws los ntawm kev ua kom muaj:
Acidic Pem Electrolyzers .
Alkaline electrolyzers .
High-ove cov khoom siv oxide electrolyzers .
Kev pab txhawb nqa catalyst
Titanium felt's ntxhib saum npoo muab cov chaw anchoring rau catalysts (e {} g}}, platinum) {2}.
Txhim kho cov lus siv thiab kev ua kom ntev los ntawm kev tiv thaiv kev tawm tsam thaum roj ntxiv .
TSEEM CEEB LUAG LOJ MOM ZOO
1. Roj Didusion Roj (GDL)
Hauv kev sib pauv nyem (PEM) electrolyzers, titanium muaj kev ua raws li lub gtalalst-coated membrane (CCM) thiab cov kab cim bipolar {} nws cov luag tw suav nrog:
Gas Thauj: Qhia qhov tshwj xeeb h₂ (cathode) thiab o₂ (anode) deb ntawm catalyst kom tiv thaiv cov chaw nquag {}}
Kev Tswj Dej Dej: Tso cai rau cov txheej txheem catalyst rau kev txuas ntxiv tshem tawm thaum tshem tawm ntau dhau mus tsis muaj kev nyab xeeb {}}}
2. Electrode
Hauv Alkaline thiab PEM lub tshuab, Titanium muaj kev pabcuam ua tus caj qaum rau cov hluav taws xob:
Kev faib khoom tam sim no: Tau muab hluavtaws hluav taws xob tam sim no tusyees ntawm cov txheej txheem catalyst, tiv thaiv hotspots .
Kev txhawb nqa mechanical: tswj txoj kev muaj txiaj ntsig zoo hauv qab cov kev cai siab (e {}}}}}}}} {{{5}
3. Corrosion-resistant barrier
Hauv chlor-alkali electrolyzers (ua chlorine thiab naoh), titanium muaj kev tiv thaiv:
Chlorine-nplua nuj ib puag ncig ntawm anode .
Caustic dej qab zib (Naoh) ntawm cathode .
Qhov no tshem tawm cov khoom siv tsis zoo rau hauv cov khoom lag luam ib txwm lossis Nickel meshes .
4. Kev Tswj Cov Thermal
Lub siab thermal conductivity ntawm titanium pab rau hauv qhov dissipation ntawm tshav kub tsim thaum lub sijhawm ua haujlwm siab tam sim no.
Tiv thaiv overheating overheating, uas tuaj yeem warp cheeb tsam lossis txo kev ua haujlwm catalyst .
