(2) Cov cuab yeej tseem ceeb suav nrog PEM electrolyzer thiab BOP;

(3) Cov qauv no raug nqi ntau dua hauv cov xwm txheej tam sim no;

 

Introduction to PEMWE

PEM dej electrolyzer siv cov khoom sib pauv hloov pauv (PEM) ua cov electrolyte thiab dej ntshiab ua cov reactant. Vim tias qhov tsis tshua muaj permeability ntawm hydrogen, PEM electrolysis muaj peev xwm tsim tau high-purity hydrogen uas yuav tsum tau tshem tawm cov dej vapor nkaus xwb, uas cov txheej txheem yooj yim thiab nyab xeeb. Lub electrolyzer yog tsim nyob rau hauv ib tug xoom-spacing qauv nrog qis dua ohmic tsis kam, uas ho txhim kho tag nrho cov efficiency ntawm electrolysis nyob rau hauv ib tug ntau compact loj. Nws txhawb nqa ntau yam kev tswj xyuas siab, nrog rau cov khoom tso tawm hydrogen siab mus txog MPa-qib, uas yog hloov mus rau lub zog tauj dua tshiab lub zog hluav taws xob hloov pauv sai.

 

1. Cov ntsiab lus ntawm PEM Electrolyzers

Zoo li cov roj cell pawg, hom electrolyzer no yog tsim los ntawm cov membrane electrodes, daim hlau thiab roj diffusion txheej. Lub anode ntawm PEM electrolyser ua hauj lwm nyob rau hauv ib tug heev acidic ib puag ncig (pH≈2) thiab nyob rau hauv lub electrolysis voltage ntawm 1.4 ~ 2.0 V, nyob rau hauv uas feem ntau uas tsis yog-noble hlau yuav corrode thiab tej zaum yuav ua ke nrog sulfonate ions nyob rau hauv. PEM, yog li txo cov proton conduction peev xwm ntawm PEM.

 

2. Catalysts

Kev tshawb fawb ntawm electrocatalysts hauv PEM electrolyzers feem ntau tsom rau cov hlau tsis zoo / oxides xws li Ir thiab Ru thiab binary thiab ternary alloys / sib xyaw oxides raws li lawv, thiab titanium-based catalysts raws li cov neeg nqa khoom. Tam sim no, kev thauj khoom ntawm iridium catalysts ntawm lub anode yog kwv yees li 1 mg / cm2, thiab kev thauj khoom ntawm Pt ntawm Pt / C-raws li catalysts ntawm cathode yog hais txog 0.4 ~ 0.6 mg/cm2. Lub Ir0.7Ru0.3Ox catalyst npaj los ntawm pab neeg tshawb fawb Italian tuaj yeem ua rau lub xovtooj ntawm electrolytic ua tiav 3.2 A·cm–2@1.85 V thaum lub Ir loading yog 1.5 mg/cm2. Lub Ir0.38/WxTi1-xO2 catalyst npaj los ntawm pab neeg tshawb fawb Giner ua kom cov electrolytic cell ua tiav 2 A cm-2@1.75 V thaum lub Ir loading yog 0 .4 mg/cm2, thiab cov ntsiab lus Ir tsuas yog 1/5 ntawm cov tshuaj electrodes. Tag nrho kev thauj khoom ntawm platinum pawg catalysts ntawm daim nyias nyias electrodes yuav tsum raug txo kom tsawg rau 0.125 mg/cm2.

Ru muaj qhov ua haujlwm zoo tshaj plaws ntawm OER catalytic tshaj li Ir, tab sis Ru tsis ruaj khov. Alloying Ru nrog Ir tuaj yeem txhim kho kev ua haujlwm thiab kev ruaj ntseg ntawm catalysts. Lub Ir{{0}}.6Sn0.4 catalyst npaj los ntawm Dalian Institute of Chemical Physics, Suav Academy ntawm Kev Tshawb Fawb tuaj yeem ua tiav 2 A cm–2@1.82 V hauv qhov ntsuas electrolyzer tag nrho. IrSn tsim cov qauv kev daws teeb meem ruaj khov, thiab cov txheej txheem ntawm alloying nrog Sn txhim kho cov dispersibility ntawm Ir, yog li pab txo cov Ir loading.

Lub National Renewable Energy Laboratory ntawm Tebchaws Meskas thiab Giner tau sib koom ua ke tsim ntau hom hlau-organic moj khaum (MOF) catalysts, uas tsuas yog tus nqi 1/20 ntawm cov tshuaj catalysts. Thaum Co-MOFG-O catalyst nyob ntawm 0.01 A / cm2, lub overpotential yuav yog 1.644 V (vs. RHE), uas ua tau zoo tshaj cov Ir catalysts nyob rau hauv ib nrab-cell decay test, nrog tag nrho-cell test yuav tsum tau ua.

 

3. PEM thiab Membrane Electrodes

Feem ntau siv cov membranes hauv PEM electrolyzers suav nrog Nafion (DuPont), Dow membrane (Lub Dow Chemical Company), Flemion (Asahi Glass Co., Ltd.) thiab Aciplex-S (Asahi Chemical Industry Company), Neosepta-F (Deshan). Chemical) thiab lwm yam. Lub DSMTM membrane tsim los ntawm Giner tau tsim nyob rau hauv ib tug loj scale, uas yog zoo dua nyob rau hauv cov nqe lus ntawm mechanical zog, thinness, ruaj khov qhov ntev thaum lub sij hawm lub hwj chim hloov, pib-up thiab kaw, thiab kev ua tau zoo nyob rau hauv tiag tiag electrolysis hlwb tshaj Nafion. Cov khoom PEM hauv tsev yog nyob rau theem sim.

 

Lub anode ntawm PEM dej electrolysis yuav tsum yog corrosion-resistant rau acid ib puag ncig thiab siab muaj peev xwm, uas yuav tsum muaj ib tug tsim nyog lub qhov tso cai rau cov roj thiab dej los ntawm. Vim yog txwv tsis pub cov tshuaj tiv thaiv ntawm PEM dej electrolysis, cov ntaub ntawv membrane electrode (xws li cov ntaub ntawv carbon) feem ntau siv hauv PEM roj hlwb tsis tuaj yeem siv rau anode ntawm dej electrolysis. 3M tau tsim ib qho nano-structured nyias zaj duab xis (NSTF) electrode, uas siv Ir thiab Pt catalysts ntawm lub anode thiab cathode, feem. Kev thauj khoom ntawm Ir thiab Pt yog 0.25mg/cm2. Cov electrode no tuaj yeem ua haujlwm ruaj khov nyob rau hauv ib puag ncig acidic thiab nyob rau hauv cov xwm txheej siab. Nws cov pas nrig zoo li array qauv ntawm qhov chaw txhim kho qhov chaw dispersibility ntawm catalysts. Proton txais yuav cov tshuaj tsuag tso ncaj qha los txo cov agglomeration ntawm catalysts, uas ua rau Pt/C thiab Ir nrog ntawm 0.1 mg/cm2 thiab Ir O2 ntawm 0.1 mg/cm2 tso rau ntawm lub Nafion117 membrane. Kev ua tau zoo ntawm ib lub xov tooj ntawm tes electrolytic zoo ib yam li cov pa hluav taws xob uas muaj cov khoom siv hluav taws xob siab (1.8 A cm–2 @ 2V), uas tuaj yeem ua haujlwm ruaj khov rau 500 teev ntawm 2.3 V.
