Saxanka laba-cirifoodka ah waa qaybta udub-dhexaadka ah ee reactor-ka, kaas oo saameyn weyn ku leh waxqabadka iyo qiimaha reactor-ka. Waqtigan xaadirka ah, saxanka laba-cirifoodka waxaa inta badan loo qaybiyaa saxan garaaf, saxan isku dhafan iyo saxan bir ah iyadoo loo eegayo walxaha.
Saxanka laba-cirifoodka ah waa mid ka mid ah qaybaha asaasiga ah ee PEMFC, doorkeeda ugu weyn waa in lagu raro gaaska iyada oo loo marayo qulqulka dusha sare, ururinta iyo qabashada hadda, kulaylka iyo biyaha ay dhaliso falcelinta. Iyadoo ku xiran nooca walxaha, miisaanka xirmooyinka PEMFCs waa qiyaastii 60% ilaa 80% qiimahana waa ilaa 30%. Marka loo eego shuruudaha shaqada ee saxanka laba-cirifoodka, iyo tixgelinta jawiga falcelinta elektiroonigga ah ee PEMFC, saxanka laba-cirifoodka ayaa looga baahan yahay inuu yeesho shuruudo sare oo loogu talagalay korantada korantada, cidhiidhiga hawada, sifooyinka farsamada, iska caabinta daxalka, iwm.
Saxan labajibbaaran marka loo eego maaddooyinka inta badan loo qaybiyo saddex qaybood oo saxan garaaf ah, saxan isku dhafan, saxan bir ah, saxan labajibbaaran graphite ayaa inta badan loo isticmaalaa gudaha PEMFC saxan labanlaab ah, korantada korantada, kuleylka kuleylka, xasilloonida wanaagsan iyo iska caabinta daxalka iyo waxqabadka kale Laakin siyaalo farsamo oo liidata, jajaban, dhibaatooyinka mishiinada ayaa horseeda dhibaatooyin qiimo sare leh oo ay ragaadiyeen warshado badan.
Garaafkasaxanka laba-cirifoodkahordhac:
Taarikada laba-cirifoodka ee ka samaysan graphite waxay leeyihiin korantada wanaagsan ee korantada, kulaylka iyo iska caabinta daxalka, waana taarikada laba-cirifoodka ee inta badan loo isticmaalo PEEMFCS. Si kastaba ha ahaatee, faa'iido darrooyinkeeda ayaa sidoo kale aad u cad: heerkulka graphitization ee saxan graphite sida caadiga ah waa ka sarreeyaa 2500 ℃, taas oo u baahan in la fuliyo si waafaqsan nidaamka kululaynta adag, iyo waqtiga waa dheer; Habka mashiinku waa mid gaabis ah, wareeggu waa dheer yahay, saxnaanta mashiinka ayaa sarreeya, taasoo keentay qiimaha sare ee saxanka garaafka; Graphite waa jilicsan yahay, saxanka la dhammeeyey wuxuu u baahan yahay in si taxadar leh loo maareeyo, isu imaatinka waa adag yahay; Graphite waa dalool, sidaa darteed taargooyinku waxay u baahan yihiin inay ahaadaan dhowr milimitir oo dhumuc ah si ay u oggolaadaan gaasasku inay kala soocaan, taasoo keentay cufnaanta hoose ee walxaha lafteeda, laakiin badeecad aad u culus.
Diyaarinta garaafyadasaxanka laba-cirifoodka：
Toner-ka ama budada garaafka ayaa lagu qasi karaa resin garaafaysan, saxaafad la sameeyay, oo garaafay heerkul sare (badanaa 2200 ~ 2800C) jawi yareynaya ama xaalado faaruq ah. Kadibna, saxanka garaafka ayaa la isku dhejiyay si loo xiro daloolka, ka dibna mashiinka xakamaynta tirooyinka ayaa loo isticmaalaa si loo farsameeyo marinka gaaska ee loo baahan yahay ee korkiisa. shaxaynta heer kulka sare iyo samaynta kanaalada gaaska ayaa ah sababaha ugu waaweyn ee qiimihiisu sarreeyo ee taarikada bipolar, iyadoo la xisaabinayo mashiinada ku dhawaad 60% wadarta kharashka unugga shidaalka.
Saxanka laba-cirifoodkawaa mid ka mid ah qaybaha ugu muhiimsan ee kaydka unugyada shidaalka. Shaqadeeda ugu muhiimsan waa sida soo socota:
1. Isku xidhka baytari kali ah
2. Keen shidaalka (H2) iyo hawada (02)
3. Ururinta iyo samaynta hadda
4. Taageero xidhmo iyo MEA
5. Si aad meesha uga saarto kulaylka ay dhaliso falcelinta
6. Daadi biyaha la soo saaray falcelinta
