Saxan laba-geesood ah oo unugyada shidaalka ah

Saxanka laba-geesoodka ah waa qaybta ugu muhiimsan ee fal-galiyaha, kaas oo saameyn weyn ku leh waxqabadka iyo kharashka fal-galiyaha. Waqtigan xaadirka ah, saxanka laba-geesoodka ah waxaa inta badan loo qaybiyaa saxanka garaafiga, saxanka isku-dhafan iyo saxanka birta iyadoo loo eegayo maaddada.

Saxanka laba-geesoodka ah waa mid ka mid ah qaybaha ugu muhiimsan ee PEMFC, doorkeeda ugu weyn waa inuu gaaska ku raro goobta socodka dusha sare, ururiyo oo uu socodsiiyo qulqulka, kulaylka iyo biyaha ay keento falgalka. Iyada oo ku xidhan nooca walaxda, miisaanka kaydka PEMFCs waa qiyaastii 60% ilaa 80% kharashkuna waa qiyaastii 30%. Sida waafaqsan shuruudaha shaqada ee saxanka laba-geesoodka ah, iyo marka la eego jawiga falgalka elektrokiimikaalka ee aashitada leh ee PEMFC, saxanka laba-geesoodka ah waxaa looga baahan yahay inuu lahaado shuruudo sare oo loogu talagalay socodka korantada, cidhiidhiga hawada, sifooyinka farsamada, iska caabbinta daxalka, iwm.

Saxanka labanlaabka ah sida ku cad agabka ayaa inta badan loo qaybiyaa saddex qaybood oo ah saxanka graphite, saxanka isku dhafan, saxanka birta ah, saxanka labanlaabka ah ee graphite waa kan ugu badan ee hadda loo isticmaalo saxanka labanlaabka ah ee PEMFC ee gudaha, conductivity korontada, conductivity kulaylka, xasillooni wanaagsan iyo iska caabinta daxalka iyo waxqabad kale laakiin sifooyinka farsamada oo liita, jajaban, iyo dhibaatooyinka mashiinka ayaa horseeda dhibaatooyin kharash sare leh oo ay la kulmaan soosaarayaal badan.

Garaafitsaxan laba-geesood ahHordhac:

Saxannada laba-geesoodka ah ee laga sameeyay graphite waxay leeyihiin koronto-qaadis wanaagsan, kuleyl-qaadis iyo iska caabin daxaleed, waana saxannada laba-geesoodka ah ee ugu badan ee loo isticmaalo PEMFCS. Si kastaba ha ahaatee, faa'iidooyinkeeda ayaa sidoo kale si cad u muuqda: heerkulka garaafka ee saxannada garaafka badanaa wuxuu ka sarreeyaa 2500℃, kaas oo u baahan in la sameeyo iyadoo loo eegayo habka kululaynta adag, waqtiguna waa dheer yahay; Habka farsamayntu waa gaabis, wareeggu waa dheer yahay, saxnaanta mashiinkuna waa sarreysaa, taasoo keentay qiimaha sare ee saxannada garaafka; Graphite waa jilicsan yahay, saxanka la dhammeeyay wuxuu u baahan yahay in si taxaddar leh loo maareeyo, isu-imaatinku waa adag yahay; Graphite waa daloolo, sidaa darteed saxannadu waxay u baahan yihiin inay ahaadaan dhowr milimitir oo dhumuc ah si ay gaasaska u kala tagaan, taasoo keentay cufnaan hoose oo walaxda lafteeda ah, laakiin badeecad dhammaystiran oo culus.

Diyaarinta garaafitkasaxan laba-geesood ah:

Budada toner-ka ama graphite-ka waxaa lagu qasaa resin graphitized ah, oo la sameeyaa cadaadis, ka dibna lagu dhejiyaa heerkul sare (badanaa 2200 ~ 2800C) jawi yar ama xaalad faakiyuum ah. Kadib, saxanka graphite-ka ayaa la mariyaa si loo xiro godka, ka dibna mashiinka xakamaynta lambarrada ayaa loo isticmaalaa in lagu farsameeyo marinka gaaska ee loo baahan yahay dushiisa. GARAAFINTA HEERKULKA SARE IYO MACHINING-KA KANAALKA GAASKA WAA SABABAHA UGU WEYN EE QIIMAHA SARE EE TAARIIKHDA BIPOLAR, IYADOO MACHINING-KU LA XISAABINAYSO ku dhawaad ​​60% WADARTA QIIMAHA MIDKA SHIDAALKA.

Saxanka laba-geesoodka ahwaa mid ka mid ah qaybaha ugu muhiimsan ee ku jira kaydka unugyada shidaalka. Shaqooyinkeeda ugu muhiimsan waa sidan soo socota:

1, Xidhiidh hal baytari ah

2, Keen shidaalka (H2) iyo hawada (02)

3, Ururinta hadda jirta iyo gudbinta

4, Taageerada xidhmooyinka iyo MEA

5, Si looga saaro kulaylka ka dhasha falcelinta

6, Biyaha ka daadi falcelinta
