Nws piav qhia txog yuav ua li cas cov khoom no daws cov teeb meem tseem ceeb ntawm ob- theem ntws hauv cov electrolyzers, suav nrog cov roj sib tw -kua kua, huab hwm coj hloov pauv, thiab kev tswj xyuas thermal.
Tsim los ntawm lub hauv paus no, qhov no yog qhov tob tob rau hauv cov txheej txheem tshwj xeeb uas cov nickel xav tau kev ua kom zoo dua ob-theem ntws. Nws qhia meej tias nws cov qauv txhawb nqa cov pa tawm li cas, txhim kho kev sib kis ntawm cov kua, sib npaug ob -theem kev sib cuam tshuam, thiab txhim kho kev tswj xyuas thermal. Tsis tas li ntawd, nws tshawb nrhiav cov ntaub ntawv siv tau thoob plaws cov thev naus laus zis electrolyzer sib txawv thiab saib ua ntej rau kev nce qib yav tom ntej, qhia txog nickel xav tau lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig zoo thiab ruaj khov hydrogen.
Yuav ua li cas Nickel Felt Optimizes Ob -Phase Flow
1. Txhawb nqa Gas Diffusion
Cov porosity siab thiab cov qauv pore tsis sib xws ntawm nickel hnov tsw muaj -tsis kam diffusion txoj hauv kev rau cov pa roj. Nyob rau hauv xoom- qhov sib txawv electrolyzers, oxygen thiab hydrogen generated nyob rau hauv lub siab tuaj yeem sai sai diffuse mus rau electrode nto los ntawm qhov pores, tiv thaiv cov pa nkag. Qhov kev tsim no ua kom muaj txiaj ntsig zoo ntawm kev tso pa tawm, txo cov npuas npog ntawm cov electrode nto, thiab yog li boosts cov tshuaj tiv thaiv electrolysis.
2. Txhim khu kev sib kis ua kua
Txoj kev ncaj-los ntawm qhov pore qauv (trapezoidal pore tsim) ntawm nickel xav tau tso cai rau cov tshuaj electrolyte ntws tawm hauv cov electrode. Qhov kev tsim no zam txoj kev tortuous pom nyob rau hauv cov ntaub ntawv ntxeem tau ib txwm, txo cov kua kis tau tus mob. Nyob rau hauv xoom- qhov sib txawv, cov xim nickel ua kom cov khoom siv electrolyte tsis sib xws, tiv thaiv kom qhuav hauv zos thiab tswj qhov chaw ruaj khov electrolysis.
3. Sib npaug ob-Phase Flow
Lub pore qauv ntawm nickel muaj qhov sib npaug ntawm cov roj thiab cov kua dej. Los ntawm kev tswj cov pore loj thiab kev faib tawm, cov nickel muaj peev xwm tswj tau cov pa roj thiab cov kua dej, kom tsis txhob muaj kev puas tsuaj vim kev sib tw khiav. Piv txwv li, nyob rau hauv siab - siab, nickel xav tiv thaiv cov roj ntau dhau thaum ua kom cov khoom siv hluav taws xob tsis tu ncua, tswj cov electrolysis zoo.
4. Txhim kho kev tswj cua sov
Lub siab thermal conductivity ntawm npib tsib xee muaj kev pab nyob rau hauv dispersing tshav kub generated thaum electrolysis. Hauv xoom- qhov sib txawv tsim, cov cua sov nyiam nyob rau hauv cov khoom siv hluav taws xob, tab sis cov qauv pore tsis sib xws ntawm nickel xav txhawb kev hloov pauv sai sai, tiv thaiv cov cua sov hauv zos. Qhov no thermal tswj muaj peev xwm ncua electrode lifespan thiab txhim kho tag nrho cov system stability.
Kev siv tswv yim ntawm Nickel Felt hauv Zero-Gap Electrolyzers
Alkaline Dej Electrolyzers
Nyob rau hauv alkaline dej electrolyzers, npib tsib xee muaj peev xwm ua hauj lwm raws li lub ntxeem tau roj diffusion electrode, ncaj qha cuam tshuam nrog alkaline electrolyte. Nws cov porosity siab thiab cov qauv pore zoo ua kom tso tawm sai sai ntawm cov pa oxygen thiab hydrogen thaum tswj cov electrolyte ruaj khov. Piv txwv li, hauv Comsol-simulated xoom- qhov sib txawv alkaline dej electrolyzer qauv, nickel xav electrodes tau siv los ua kom zoo dua ob-theem ntws, txhim kho electrolysis efficiency.
PEM Electrolyzers
Thaum PEM electrolyzers feem ntau siv cov khoom sib pauv hloov pauv, npib tsib xee muaj peev xwm ua haujlwm pabcuam hauv qee cov qauv tsim los txhim kho cov pa tawm thiab xa cov kua. Nws cov corrosion kuj thiab txhua yam muaj zog ua kom ruaj khov ua haujlwm nyob rau hauv acidic ib puag ncig, muab kev pabcuam ntxiv rau PEM electrolyzers.
AEM Electrolyzers
Nyob rau hauv anion exchange membrane (AEM) electrolyzers, npib tsib xee xav ua raws li cov ntxeem tau thauj txheej (PTL), ncaj qha cuam tshuam nrog AEM membrane. Nws cov qauv optimizes roj thiab kua ntws txoj kev, txo cov huab hwm coj hloov tsis kam thiab txhim kho hydrogen ntau lawm efficiency. Piv txwv li, hauv AEM hydrogen ntau cov tshuaj tiv thaiv, qhov ncaj -los ntawm qhov pore tsim ntawm npib tsib xee tau ua rau muaj txiaj ntsig zoo rau cov roj tso tawm thaum tswj cov hluav taws xob tsis sib xws.
Yav tom ntej Outlook rau Nickel Felt
Raws li hydrogen zog thev naus laus zis txuas ntxiv mus, daim ntawv thov kev cia siab ntawm nickel hnov hauv xoom-gap electrolyzers yog qhov loj. Nyob rau hauv lub neej yav tom ntej, nickel xav tsim yuav ua kom zoo ntxiv, xws li los ntawm kev kho qhov porosity thiab pore qauv, kom hloov mus rau siab dua thiab xav tau ntau dua electrolysis ib puag ncig. Tsis tas li ntawd, scaled- nce kev tsim cov nickel xav yuav txo cov nqi, tsav nws txoj kev saws me nyuam loj hauv - nplai ntsuab hydrogen ntau lawm.
Cov khoom tshwj xeeb ntawm npib tsib xee ua rau nws yog cov khoom siv tseem ceeb rau kev ua tiav ob- theem ntws hauv xoom- qhov sib txawv electrolyzers. Los ntawm kev txhawb nqa roj diffusion, txhim kho cov kua kis tau tus mob, ntsuas ob -theem ntws, thiab txhim kho kev tswj xyuas thermal, npib tsib xee tau txais txiaj ntsig zoo ntawm electrolyzer kev ua tau zoo thiab ruaj khov. Nrog rau kev txhim kho thev naus laus zis, nickel xav tau txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv hydrogen zog sector, pab txhawb kev hloov pauv hluav taws xob thoob ntiaj teb.
