Ni ukubera iki Anion Guhana Membrane (AEM) Ibikoresho bya hydrogène Bisaba Amashanyarazi Yashizwemo Amashanyarazi?

Isiganwa ryisi yose ryigenga ryigenga ryingufu zashyize Anion Exchange Membrane (AEM) electrolysis yamazi kumwanya wambere mubyara hydrogène. Muguhuza ibyiza byigiciro cyisi-nyinshi, catisale itagira PGM hamwe nuburyo bworoshye bwimikorere ya sisitemu ishingiye kuri membrane, ikoranabuhanga rya AEM ryiteguye kuzamura imishinga yigenga ya hydrogène yigenga mu nganda zikomeye, kuringaniza imiyoboro, hamwe no gutwara zero-karubone.

Nyamara, integer ya stack ihura nikibazo gikomeye cyubukanishi nubumashini kumpera yumurongo: ibyapa byanyuma byubatswe. Muri kilowatt nyinshi cyangwa megawatt ya AEM, isahani yanyuma igomba gukomeza itara riremereye kugirango itange kashe imwe mu ngirabuzimafatizo zibarirwa mu magana, irinde hydrogène n’umuvuduko ukabije wa ogisijeni. Icyarimwe, ibice byimbere bikwirakwiza amashanyarazi ya alkaline electrolytike (mubisanzwe hydroxide ya potasiyumu 1%, KOH, cyangwa sodium bicarbonate, NaHCO₃, kuri 60 ° C kugeza 80 ° C).

Bare aluminium isanzwe ni amphoteric; guhura na alkaline lye itera imiti yihuta, kurekura gaze ya hydrogene no gusenya geometrie. Ibinyuranye, ibyuma bikomeye bidafite ingese cyangwa isahani ya nikel-alloy isahani yongeraho uburemere buke, byongera inshuro ya CNC yo gusya, kandi ugashyira imitwaro irenze kumurongo wa kontineri. Imiti yashizwemo isahani ya aluminiyumu - ikomatanya plaque ya aluminiyumu itanga umusaruro mwinshi (6000/5000) hamwe na fluoropolymer yuzuye, idafite pinhole idafite alkali irwanya fluoropolymer cyangwa epoxy-ceramic hybrid barrière -itanga igisubizo cyiza cyubwubatsi. Bitandukanya intungamubiri ya aluminiyumu n’igitero cya alkaline, ihagarika amashanyarazi y’amashanyarazi yayobye, ikuraho guhindagurika, kandi igabanya uburemere bwimiterere ya stack hejuru ya 60% ugereranije nicyuma kitagira umwanda..

Guhitamo Isahani yuburyo bwo hejuru-Kumashanyarazi

Ibikoresho bya AEM electrolyzer bisaba guhoraho, guhuza imashini kugirango ikomeze amashanyarazi kandi ikumire gaze yaka umuriro:

Amavuta Yubatswe Yumusaruro mwinshi: Icyemezo cya plaque 6061-T6 na 5083 cyemewe gitanga imbaraga nyinshi (240 MPa kugeza 275 MPa), gitanga ubukana bwuburyo bukenewe kugirango hirindwe ikigo cyunama mugihe perimetero ya karuvati-inkoni yometse kuri preload yuzuye.

Kunesha ibihano by'ibiro bidafite umuyonga: Hafi ya kimwe cya gatatu cy'ubucucike bw'ibyuma (2.70 g / cm³ umurongo wa 8.00 g / cm³), isahani yuzuye ya aluminiyumu yagabanije ibyapa byanyuma byubatswe hejuru ya 60%. Uku kuzigama kuremereye kwemerera ibishushanyo byinshi gushyirwaho imbere yikigo gisanzwe kitarinze gukurura igorofa ihenze cyangwa amafaranga yo gukodesha crane iremereye.

Uburinganire bwa Dimensional Kuringaniza Ubushyuhe: Aluminiyumu yubaka-isukuye cyane igumya isahani hejuru yubushyuhe bwo gukora kuva itangiye ubukonje (15 ° C) kugeza ku mikorere ikomeza (80 ° C), bikarinda impanuka ya gaze ya perimeteri hamwe nu cyuho cya kashe.

Uruganda-rushyirwa mu bikorwa Imiti irangiza

Bare aluminiyumu ihita ikora imiti ya alkaline. Sisitemu ya barrière yakize ikuraho burundu iyi miti mibi:

Umuyoboro mwinshi wa Alkaline-Resistant Polymer-Ceramic Formulaire: Yateguwe byumwihariko kugirango irwanye guhorana umubyibuho ukabije wa alkaline electrolyte ibisubizo (pH 9.0 kugeza 14.0) nta kubyimba, koroshya, cyangwa kubyimba amasaha ibihumbi icumi yo gukora.

Gukwirakwiza amashanyarazi yuzuye: Inzitizi idatwara imiyoboro itanga imbaraga zo gusenyuka hejuru ya dielectric, ikuraho imigezi yatembye ikoresheje karuvati kandi ikarinda umutekano w'abakozi b'ibihingwa bidasabye impapuro zitandukanye.

Ibipimo bya tekiniki & ubucuruzi

Icyerekezo Cyingufu Cyisi & B2B Kwishura Ubucuruzi

Ibibazo

Q1: Kuki bidashoboka ko aluminiyumu yambaye ubusa ikoreshwa kuri plaque ya AEM electrolyzer?

Igisubizo: AEM electrolyzers ikwirakwiza electrolyte ya alkaline (mubisanzwe 1% KOH cyangwa NaHCO3). Bare aluminium ni icyuma cyitwa amphoteric gishonga vuba mubidukikije bya alkaline, bigakora gukora aluminiyumu na gaze ya hydrogen. Imiti ya inert irasabwa gutandukanya icyuma na electrolyte.

Q2: Niki gituma aluminiyumu 6061-T6 ikomera bihagije kugirango isimbuze ibyuma biremereye bitagira ibyuma?

A: 6061-T6 itanga imbaraga zumusaruro urenga MPa 240. Mugihe ibyuma bifite modulus ihanitse ya elastique, kongera umubyimba wa plaque ya aluminiyumu bitanga gato ubunini buke mugihe ugabanya uburemere bwibisahani hejuru ya kimwe cya kabiri, bikabuza ikigo kunama munsi yiziritse ku nkoni.

IKIBAZO: Ese igipfundikizo cyo gukingira kizacika cyangwa gishishwa munsi ya karuvati iremereye?

Igisubizo : No. Iyo ibitsike bifatanye, igipfundikizo cyihanganira imizigo yo kwikuramo irenga MPa 100 ikikije isabune ya bolt hamwe na gaze ya gaze itanyeganyega, irasaze, cyangwa ngo isibe.

Q4: Nigute guhinduka kuva mubyuma bidafite ingese ukajya kuri aluminiyumu isize ibiciro byo gukora?

Igisubizo: Aluminium igabanya igihe cyo gusya CNC hafi bibiri bya gatatu, bigabanya cyane kwambara ibikoresho no gukora imirimo. Byongeye kandi, amasahani yoroheje agabanya ibiciro byo kohereza, koroshya ergonomique yo guterana, kandi bikuraho ibikenerwa byamaduka manini aremereye.

Q5: Nigute gutwikira birinda amakosa yubutaka bwamashanyarazi mubice byinshi?

Igisubizo: Igipfundikizo cya polymer-ceramic ntigikora, gitanga imbaraga zo guhangana na dielectric (> 15 kV / mm). Ibi bitandukanya imbaraga zamashanyarazi zikoreshwa mumashanyarazi yo hanze, ikarinda imigezi yayobye no kurinda abakozi bakora.

Umwanzuro

Guhitamo no gutondekanya imiti yashizwemo aluminiyumu ya plaque ya AEM electrolyzer:

Ubunini Ubunini Kuri Span Ratios kugirango wirinde kunama: Kugaragaza umubyimba ntarengwa wa plaque ya mm 35 kugeza kuri mm 60 (ukurikije agace ka selile ikora) ukoresheje 6061-T6 cyangwa 5083 byemewe kugirango umenye neza ko gutandukana hagati ya mm 0,05 munsi ya karuvati yuzuye.

Manda Yuzuye Dielectric & Alkali-Resistant Coating Ibisobanuro: Saba guhuza epoxy-ceramic cyangwa fluoropolymer byemewe byemejwe ko wibizwa muri 60 ° C kugeza 80 ° C bivanga KOH hamwe nimbaraga za dielectric zirenga 10 kV / mm.

Shimangira 100% Ikizamini cya Spark Interfaces: Saba ibyemezo byubuziranenge bwuruganda rwemeza ibizamini byikiruhuko cyumuvuduko mwinshi mubyambu byose byamazi yimbere hamwe na O-ring groove kugirango byemeze zeru zinone mbere yo guterana.
