PEM electrolysis cell yog ib qho ntawm ntau cov thev naus laus zis hydrogen ntau lawm, uas siv cov khoom siv hluav taws xob sib hloov ua los ntawm polyfluoro sulfonic acid zaj duab xis thiab dej ntshiab ua cov reactant. Nws muaj cov yam ntxwv ntawm high hydrogen purity, yooj yim qauv thiab txheej txheem, thiab kev nyab xeeb siab. Nyob rau tib lub sijhawm, nws yog qhov tsim nyog rau kev hloov pauv sai dua lub zog hluav taws xob hluav taws xob tawm tswv yim, thiab yog li ntawd tau nyiam los ntawm kev lag luam.
Vim yog siv perfluorosulfonic acid (PFSA) daim nyias nyias, qhov chaw ua haujlwm ntawm PEM electrolysis cell yog acidic. Tsis tas li ntawd, qhov siab voltage thiab oxygen tso tawm ntawm sab anode tsim ib puag ncig oxidation hnyav. Yog li ntawd, lub phaj bipolar thiab roj diffusion txheej ntawm PEM electrolysis cell yuav tsum muaj corrosion-resistant zog. Cov khoom siv xws li graphite, stainless hlau, thiab titanium tuaj yeem siv tau, txhua tus muaj nws tus kheej zoo thiab qhov tsis zoo, tab sis titanium muaj cov khoom zoo dua.
Txawm tias nyob rau hauv acidic thiab siab anode tej yam kev mob, titanium yog qhov tsawg tshaj plaws corrosive cov ntaub ntawv thiab yog kuj yooj yim rau tsim ntau yam ntxeem tau xov xwm. Yog li ntawd, titanium mesh / felt / ua npuas ncauj / sintered hmoov yuav siv tau raws li GDL ntawm PEMWE anode.
Siv titanium xav ua piv txwv, nws cov txheej txheem tsim khoom suav nrog xaiv cov sponge titanium zoo, kho cov txheej txheem los tsim cov titanium crystals raws li titanium xav tau cov ntsiab lus hlau, forging rau hauv qhov xav tau, machining titanium phaj rau hauv titanium fibers, tso. titanium fibers, thiab high-temperature sintering los tsim ntxeem tau titanium xav.
