Ese Micro-Embossed Coed Foil Yongera Ikwirakwizwa rya Gaz-Amazi Yimbere Imbere Yumuvuduko Ukabije w'amashanyarazi?

Mu gihe ibihugu by’inganda byihutisha ibikorwa remezo bya hydrogène ya gigawatt nyinshi kugirango ibone ubwigenge bw’ingufu no kwangiza imyanda iremereye, electrolysis y’amazi y’umuvuduko mwinshi (ikorera kuri 30 bar kugeza kuri 50 bar) yabaye urugero rwa zahabu. Igikorwa cyumuvuduko ukabije gikuraho ibikenerwa byo gukanika hydrogène yo hanze, bizigama amamiriyoni y amadolari mu bikoresho bikuru by’imari no gukoresha amashanyarazi parasitike.

Nyamara, gukorera kumuvuduko mwinshi uri munsi yumuvuduko mwinshi bizana umuvuduko ukabije wamazi: kugabanuka kwa gaz-ibice bibiri . Mugihe umwuka wa ogisijeni na hydrogène bigenda byihuta cyane hejuru ya catalizator, micro-bubbles ihurira hamwe mumyenda ya gaze yuzuye ifatanye na plaque bipolar hamwe na ecran ya flux. Iyi 'bubble pinning ' ibuza amazi yamazi kugera kumurongo wa reaction, gukora ahantu hashyushye, kwihuta kwangirika kwa membrane, no gukurura ibihano bikabije bya selile. Mu mateka, abubatsi ba stack bashingiraga kuri CNC ihenze ya titanium mesh cyangwa platine-ya matsinda mato (PGM) yubatswe na titanium, idashobora kuyobora kwimura gaze neza kandi ikanatwara amafaranga y’ibiciro by’ibiciro bihindagurika.

Micro-yashizwemo na aluminiyumu itanga igisubizo cyemejwe, cyinjiza cyane muri iki kibazo. Yakozwe hifashishijwe uburyo bukomeza, busobanutse neza bwa coil gushushanya kandi burangizwa na inert ya chimique, lacquer de la récitifique, iyi fayili ya injeniyeri ikubiyemo inzira ya micro-capillary ikomeza. Ihatira kwihuta kwinshi, ikuzuza electrolyte imwe, ikuraho parasitike selile ikabije, kandi igabanya ibiciro byo gukwirakwiza ibicuruzwa hejuru ya 60% ugereranije ninteko ya titanium.

Umuyoboro mwinshi wa Aluminium Foil nkuburyo bwimiterere ya Substrate

Uturemangingo twinshi twa electrolyzer selile dusaba uburinganire buringaniye hamwe nubushyuhe bwo hejuru bwumuriro hejuru yibice bya selile:

1000/8000 Urukurikirane rwinshi-rufite isuku: Ifumbire ya aluminiyumu ifatanye kandi itajegajega (gipima kuva kuri mm 0,08 kugeza kuri mm 0.3) itanga uburebure budasanzwe no guhindagurika ku buso, bigatuma mikoro-mikorobe cyangwa stucco ishushanya neza idafite mikorobe cyangwa ibisekuru bya pinhole.

Kwimura Ubushyuhe Bwihuse Kurwanya Ahantu Hashyushye: Aluminiyumu itanga amashanyarazi menshi hejuru ya 210 W / m · K - inshuro zirenga cumi n'eshatu kurenza Titanium yo mu cyiciro cya 2 (~ 16 W / m · K). Mugihe gikora-cyinshi-cyinshi, fayili ikuramo ubushyuhe mukarere ka gaze-mu mufuka ako kanya, ikarinda inteko ya membrane-electrode (MEA) kugirango idashyuha.

Ubudahangarwa bw’umuvuduko ukabije wa hydrogène Embrittlement: Bitandukanye nicyuma cya ferritic kitagira ibyuma byangirika bikabije munsi ya bar 30 kugeza kuri 50 bar hydrogène itose, latike ya aluminiyumu yo mu maso ikomeza kuba ihindagurika rwose kandi idashobora kwihanganira mumyaka myinshi ya serivise.

Imikorere ikora & Inert Barrier Coatings

Icyuma kibisi ntigomba na rimwe guhura na acide cyangwa alkaline electrolyte imigezi itaziguye:

Pinhole-Free Conductive Polymer Matrices: For cathode-side and bipolar interfaces, conductive lacquers embedded with sub-micron metallic particles maintain low Interfacial Contact Resistance (ICR under 5 mΩ·cm²), preventing the formation of native, non-conductive aluminum oxide films.

Imiti ya Alkali / Acide Yimiti: Kuri sisitemu yamazi ya alkaline cyangwa AEM, inzitizi zihariye za termoset polymer zirwanya kwibiza gushiramo amashanyarazi (60 ° C kugeza 80 ° C) nta kubyimba, kubyimba, cyangwa guhindagurika, byemeza ko imiti yamara igihe kirekire.

Ibibazo

Q1: Nigute ubuso bwashizweho na mikoro butezimbere kwimuka gazi ugereranije nurupapuro ruringaniye?

. Igisubizo Impinga n’ibibaya bya fayili yometseho mikorobe ikora imiyoboro ya capillary ikurura amazi munsi yibibyimba, ikabikuramo hejuru yisahani ikabisohora mumazi nyamukuru.

Q2: Ifu ya aluminiyumu irashobora kwihanganira umuvuduko mwinshi (30 bar kugeza 50 bar) imbere ya electrolyzer?

Igisubizo: Yego. Umuvuduko uri imbere ya electrolyzer ikora iringaniza hydrostatike hejuru ya selile. Urupapuro rukora nk'imbere-ruyobora kandi rukingira ururondogoro rushyigikiwe na plaque bipolar yubatswe, bivuze ko rufite imbaraga zinyuranye zitemba aho kuba imitwaro idashyigikiwe.

IKIBAZO: Ese imashini yangiza imashini yangiza cyangwa igasenya hejuru yuburinzi?

Igisubizo: Oya, byatanzwe muruganda rwabitswe mbere hamwe na sisitemu ya thermoset polymer ikoreshwa. Ipitingi yateguwe kugirango ihindurwe 0T kugeza 1T, irambuye hamwe na substrate ya aluminiyumu mugihe cyo gushushanya idafite micro-fissing, flake, cyangwa gutakaza gufatira hamwe.

Q4: Nigute guhindukira ukava muri titanium ukajya muri aluminiyumu ya micro-igiciro gito?

Igisubizo: Micro-yometse kuri aluminiyumu igabanya ibiciro byibanze hejuru ya 60%, ikuraho ibikenerwa byo gutera kashe ihenze ipfa, kandi igera kubishushanyo mbonera. Ibi bituma ababikora bagabanya ibice kubunini no kubiteranya ako kanya, bikiza ibyumweru byo guhimba.

Q5: Ni ukubera iki ubushyuhe bwa aluminiyumu ari bwiza mu ngirabuzimafatizo zikomeye?

Igisubizo: Gukorera kumurongo mwinshi bitanga ubushyuhe bukomeye bwaho. Aluminiyumu itanga ubushyuhe bwikubye inshuro cumi n'eshatu kurenza titanium (210 W / m · K na 16 W / m · K), ikwirakwiza ahantu hashyushye ahantu hashobora kuzenguruka amazi kugirango hirindwe kwangirika kwubushyuhe bwa membrane.

Umwanzuro

Kugirango uhuze neza micro-yometseho aluminiyumu foil mumashanyarazi yumuvuduko mwinshi:

Hitamo Umwirondoro Ufite Ingano Kuri Fluid Viscosity: Kugaragaza ubujyakuzimu bwimbitse buri hagati ya 25 µm na 75 µm bitewe n'umuvuduko w'akagari n'umuvuduko wa electrolyte kugirango uhuze capillary weting n'imbaraga zo gutemba.

Gutanga Manda Yateganijwe Gutanga Igiceri: Saba impuzu zuzuye, zashyizwe mu ruganda ku biceri bishushanyijeho kugirango ukureho ibyumba byo mu rugo byoza, gutera, no guteka.

Saba 100% Icyemezo cya Zeru-Pinhole Icyemezo: Menya neza ko ibyangombwa bitanga byemeza ko igeragezwa ridahwitse ridashobora kwangirika kurubuga rwashushanyijeho kugirango habeho inzitizi zuzuye zo kurwanya ibitero by’imiti.
