Iyini ipuleti le-graphite bipolar?

Ipuleti le-Graphite bipolariyisakhi esiyinhloko esisetshenziswa emishinini ye-electrochemical efana namaseli kaphethiloli nama-electrolyzer, ngokuvamile enziwe ngezinto ze-graphite ezihlanzekile kakhulu. Idlala indima ebalulekile ekuphenduleni kwe-electrochemical, esetshenziswa kakhulu ukuqhuba ugesi, ukusabalalisa amagesi okusabela (njenge-hydrogen ne-oxygen), kanye nokuhlukanisa izindawo zokusabela. Ngenxa yokuthi izinhlangothi zayo ezimbili zithinta i-anode ne-cathode yamaseli angawodwa aseduze, zakha isakhiwo "se-bipolar" (olunye uhlangothi luyinsimu yokugeleza kwe-anode kanti olunye uhlangothi luyinsimu yokugeleza kwe-cathode), ibizwa ngokuthi i-bipolar plate.

Isakhiwo sepuleti le-graphite bipolar

Amapuleti e-graphite bipolar ngokuvamile aqukethe izingxenye ezilandelayo:
1. Insimu Yokugeleza: Ubuso bepuleti le-bipolar buklanywe ngesakhiwo sensimu yokugeleza eyinkimbinkimbi ukuze kusatshalaliswe ngokulinganayo igesi yokusabela (njenge-hydrogen, i-oxygen noma umoya) futhi kukhishwe amanzi akhiqizwayo.

2. Isendlalelo esiqhubayoIzinto ze-Graphite ngokwazo zinokuqhuba kahle komoya futhi zingaqhuba ugesi ngempumelelo.

3. Indawo yokuvala: Imiphetho yamapuleti e-bipolar ivame ukuklanywa ngezakhiwo zokuvala ukuze kuvinjelwe ukuvuza kwegesi nokungena koketshezi.

4. Iziteshi zokupholisa (ongakukhetha): Kwezinye izinhlelo zokusebenza ezisebenza kahle kakhulu, iziteshi zokupholisa zingaklanywa ngaphakathi kwamapuleti e-bipolar ukulawula izinga lokushisa lokusebenza kwemishini.

Imisebenzi yamapuleti e-graphite bipolar

1. Umsebenzi wokuqhuba:

Njenge-electrode yemishini ye-electrochemical, ipuleti le-bipolar linesibopho sokuqoqa nokuqhuba ugesi ukuqinisekisa ukukhishwa kwamandla kagesi okuphumelelayo.
2. Ukusatshalaliswa kwegesi:

Ngokuklanywa kwesiteshi sokugeleza, ipuleti le-bipolar lisabalalisa ngokulinganayo igesi yokusabela kungqimba lwe-catalyst, likhuthaza ukusabela kwe-electrochemical.
3. Ukuhlukanisa izindawo zokusabela:

Ku-fuel cell noma i-electrolyzer, ama-bipolar plate ahlukanisa izindawo ze-anode kanye ne-cathode, avimbele amagesi ukuthi angaxubani.
4. Ukushabalalisa ukushisa kanye nokuphuma kwamanzi:

Amapuleti e-bipolar asiza ekulawuleni izinga lokushisa lokusebenza kwemishini futhi akhiphe amanzi noma eminye imikhiqizo ephumayo ekhiqizwa yi-reaction.
5. Ukusekelwa kwemishini:

Amapuleti e-bipolar ahlinzeka ngokusekelwa kwesakhiwo se-electrode ye-membrane, okuqinisekisa ukuzinza nokuqina kwemishini.

Kungani ukhetha i-graphite njengezinto zepuleti le-bipolar?

Izakhiwo zezinto ezibonakalayo zamapuleti e-graphite bipolar
●Ukuqhuba okuphezulu:

Ukumelana okukhulu kwe-graphite kuphansi njengo-10-15μΩ.cm (kungcono kuno-100-200 μΩ·cm weipuleti lensimbi le-bipolar).

●Ukumelana nokugqwala:

Cishe akukho ukugqwala endaweni ene-asidi yamaseli kaphethiloli (pH 2-3), futhi impilo yesevisi ingafinyelela emahoreni angaphezu kuka-20,000.

●Ilula:

Ubuningi bungaba ngu-1.8 g/cm3 (7-8 g/cm3 yepuleti le-bipolar lensimbi), okuwusizo ekunciphiseni isisindo ezisetshenziswa emotweni.

●Impahla yokuvimbela igesi:

Isakhiwo esiminyene se-graphite singavimbela ngempumelelo ukungena kwe-hydrogen futhi siphephile kakhulu.

●Ukucutshungulwa okulula:

Izinto ze-graphite kulula ukuzicubungula futhi zingenza ngezifiso imiklamo yeziteshi zokugeleza eziyinkimbinkimbi kanye nosayizi ngokwezidingo.

Amapuleti e-graphite bipolar akhiqizwa kanjani?

Inqubo yokukhiqizaipuleti le-bipolar le-graphitekufaka okulandelayo:
●Ukulungiswa kwezinto ezingavuthiwe:

Sebenzisa i-graphite yemvelo ehlanzekile kakhulu (>99.9%) noma i-graphite yokwenziwa ewuphuphu.

Faka i-resin (njenge-phenolic resin) njengesihlanganisi ukuze uthuthukise amandla omshini.

●Ukubumba Kokucindezela:

Izinto ezixubile zifakwa esikhumbeni bese zicindezelwa ngaphansi kokushisa okuphezulu (200-300℃) kanye nomfutho ophezulu (>100 MPa).

●Ukwelashwa kwe-Graphitization:

Ukushisa kufike ku-2500-3000℃ emoyeni ongasebenzi kahle kubangela ukuthi izinto ezingezona ikhabhoni ziguquguquke futhi zakhe isakhiwo se-graphite esiminyene.

●Ukucubungula umgijimi:

Sebenzisa imishini ye-CNC noma ama-laser ukuze uqophe iziteshi ze-serpentine, parallel noma interdigitized (ukujula okungu-0.5-1 mm).

●Ukwelashwa kwendawo:

Ukufuthwa nge-resin noma insimbi (njengegolide, i-titanium) kunciphisa ukumelana nokuxhumana futhi kuthuthukisa ukumelana nokuguguleka.
