PEM electrolytic cell muaj peb yam tseem ceeb: lub phaj bipolar, roj diffusion txheej, thiab electrode. Tam sim no, cov phaj bipolar thiab cov roj diffusion txheej tuaj yeem tsim tawm hauv tsev, thaum kev txhim kho cov khoom siv hluav taws xob hauv tsev tseem tab tom ua tiav.
Cov txheej txheem ntau lawm rau cov phaj bipolar zoo ib yam li cov semiconductors thiab chips. Nws suav nrog kev pub mis, tu cov khoom, maj mam raug, txhim kho, kho, ua kom sov, etching, pwm tso tawm, tshuaj xyuas, thiab khaws cov khoom tiav. Ntau yam hlau thiab alloy series, xws li stainless hlau, titanium alloy, thiab npib tsib xee-raws li alloys, yog haum rau xaiv cov hlau bipolar daim hlau.
Txhawm rau kom muaj kev pab cuam lub neej, lub phaj bipolar thiab roj diffusion txheej yuav tsum tau txheej. Cov kev xaiv muaj xws li cov txheej txheem tiv thaiv corrosion xws li platinum, iridium, kub, thiab carbon-based coatings. Lub thickness ntawm txheej plays lub luag haujlwm tseem ceeb. Thaum cov tshuaj zoo tib yam plating ua tiav qhov tuab ntawm 0.1 hli, txheej txheej TopTi tuaj yeem ua tiav qhov tuab ntawm 0.5 microns, ua rau txo nqi. Plasma ntxuav ntawm qhov chaw ua ntej txheej thiab kev khiav hauj lwm hauv lub tshuab nqus tsev ua rau muaj adhesion ntau dua piv rau cov dej plating.
Cov ntaub ntawv xaiv tau rau titanium fiber ntau txheej txheej muaj xws li titanium, nickel, stainless hlau, thiab alloys. Txawm li cas los xij, muaj kev cuam tshuam rau kev siv nickel-based fiber ntau, thiab nws kuj tseem kim dua hauv khw. Lub tuam txhab muaj qhov zoo ntawm nws tus kheej ua cov ntaub ntawv fiber ntau thiab muab cov khoom lag luam customized raws li cov neeg siv khoom xav tau. Tam sim no, cov khoom tseem nyob rau theem kev sim.
Piv nrog rau alkaline electrolysis dej hydrogen ntau lawm technology, PEM hydrogen ntau lawm ntsib cov teeb meem vim tsis muaj scaled thiab localized cov ntaub ntawv tseem ceeb, ua rau cov khoom kim heev. Cov phaj bipolar thiab cov roj diffusion txheej yog cov khoom tseem ceeb ntawm PEM dej electrolysis. Thaum cov ntsiab lus tseem ceeb no tau paub thiab nyob hauv cheeb tsam, cov cuab yeej siv ntawm PEM electrolytic hlwb tuaj yeem txo qis rau yav tom ntej, yog li tsav txoj kev loj hlob ntawm kev lag luam hydrogen.
