Mumasisitimu esimba remagetsi anogara achichinja,graphite yakanzwaInoonekwa sechinhu chinoshandiswa nekabhoni, chine hunhu hwakasiyana hwekuvaka, magetsi, uye makemikari. Kunyange hazvo isiri magadzirirwo ese emagetsi anoshandisa graphite felt pasi rose, basa rayo—kunyanya mumasisitimu emagetsi epamusoro uye mahybrid fuel cell—rakawedzera kukwezva kutariswa kwemainjiniya nevagadziri vemasisitimu vakazvipira kuvandudza mashandiro emagetsi emagetsi pamatanho ese ari maviri uye maitiro.
I. Hunhu hwepakutanga hweGraphite felt
Kubva pamaonero esainzi yezvinhu, graphite felt inetwork ine maburi matatu inoumbwa nefibers dzekabhoni dzakarukwa, dzinowanzo torwa kubva ku polyacrylonitrile (PAN) kana pitch precursors uye dzakagadzirwa ne graphitized pakupisa kwakanyanya. Chimiro ichi chinopa graphite felt ine hunhu hwakasiyana-siyana hunonyanya kukosha munzvimbo dzemagetsi:
● Kufambiswa kwemagetsi kwakanyanya: kuve nechokwadi chekutakura maerekitironi
● Kupinda kwemvura kwakakwira (>90%): zvinoita kuti gasi kana mvura zvipinde
● Kudzivirira ngura zvakasimba: inogona kugadziriswa nemamiriro ezvinhu ane acidity/oxidation (semuenzaniso, PEMFCs)
● Kugona kugadzikana kwekumanikidzwa: zvinobatsira pakugadzikana kwekubatana
● Kudzivirira kupisa kwakanyanya: kwakakodzera masisitimu emagetsi ekupisa kwakanyanya
II. Basa reGraphite Felt muMasero Akasiyana eFuel
Kushandiswa kwegirafiti yakafendwa muhunyanzvi hwema fuel cell kunosiyana zvakanyanya zvichienderana nekugadzirwa kwesystem.
1. Mumabhatiri emvura (semuenzaniso, mabhatiri evanadium redox flow) - Core Electrode Material
Mumasystem emagetsi emagetsi echikamu chemvura - kunyanya mabhatiri ekuyerera, anowanzo kurukurwa pamwe chete netekinoroji yemasero emafuta nekuda kwemitemo yavo yakafanana yemagetsi - graphite felt inoshandiswa sechinhu chikuru che electrode. Nzvimbo yayo yepamusoro yepamusoro uye chimiro chakabatana chine maburi zvinopa nzvimbo dzakawanda dzinoshanda dzekuita redox uku zvichikurudzira kuyerera kwe electrolyte. Maitiro ekugadzirisa pamusoro akadai sekushanda kwekupisa kana oxidation anowanzo shandiswa kuwedzera kunyorova kwayo uye basa re catalytic, zvichikanganisa zvakananga kushanda zvakanaka kwesystem uye kugadzikana kwe cycle.
2. MuPEM Fuel Cells (Proton Exchange Membrane Fuel Cells) - Rubatsiro rweKupararira/Zvinhu zvekutsigira
Kusiyana neizvi, mumasisitimu eproton exchange membrane (PEM), graphite felt haisi sarudzo yakajairika ye gas diffusion layer (GDL). Carbon paper kana carbon cloth inonyanya kukosha nekuda kwekugona kwayo kuchinjika mu conductivity, mechanical stiffness, uye manufacturability. Zvisinei, graphite felt yakawana mashandisirwo akasiyana mune mamwe maPEM configurations, kunyanya apo kutarisirwa kwemvura kwakanyanya kana kugoverwa kwegasi kunodiwa. High porosity yayo inogona kuvandudza mass transfer performance pasi pehunyoro hwakawanda kana mamiriro ehunyoro, asi izvi zvinounza kutengeserana mu contact resistance uye compressive stack, izvo zvinofanirwa kugadziriswa kuburikidza nekudzora stack nekumanikidzwa kwakagadzirwa zvakanaka.
3. Mumasero emafuta anodziya zvakanyanya (maSOFC, nezvimwewo) - Auxiliary Conductive/Sealing Buffer
Mumasystem anodziya zvakanyanya (semuenzaniso, maelectrolyzer e-solid oxide), graphite felt haiwanzo shandiswa sechinhu chikuru chemagetsi nekuda kwehukuru hwezvinhu zveceramic mumaelectrodes ne electrolyte. Zvisinei, inogona kushanda mabasa ekuwedzera, kusanganisira conductive buffering, sealing support, kana kugadzirisa kuwedzera kwekupisa mumidziyo yekuwedzera kana nzvimbo dzepakati pemafekitori. Kunyange zvazvo mabasa aya ari echipiri, akakosha pakuona kugara kwenguva refu uye kusimba kwemuchina mumamiriro ekushanda akaipisisa.
III. Pfupiso yeMabasa Akakosha muTekinoroji yeMasero eFuel
Kubva pamaonero einjiniya yemaitiro, kukosha kwegraphite felt kuri mukukwanisa kwayo kubatanidza mabasa akawanda mukati mechinhu chimwe chete. Maumbirwo ayo ane mativi matatu anobvumira kuumbwa kwema electrochemical interfaces akarebeswa, zvichiwedzera nzvimbo ye reaction pasina kuwedzera zvakanyanya footprint yesystem. Panguva imwe chete, inobatsira mukugoverwa kwemvura kwakafanana, kuderedza ma gradients e concentration uye kuderedza kurasikirwa kwe polarization kunokonzerwa nemiganhu yekufambisa kwehuwandu. Kubatanidzwa kwakakodzera kwegraphite felt kunobatsira kuumbwa kwe continuous conductive network, nokudaro zvichideredza resistance yemukati uye kuvandudza kushanda zvakanaka kwesystem.
Uyezve, inoita basa rakakosha mukugadzirisa mashandiro emakanika uye magungano. Kusimba kwegirafiti uye kugona kwayo kugadzira zvinhu kunoita kuti ikwanise kuchinjika nezvinodiwa pakugadzira uye kuchengetedza kubatana kwakasimba pakati pemagadzirirwo emagetsi pasi pemamiriro ekurongedza. Hunhu uhwu hunonyanya kubatsira mumasystem emhando yepamusoro kana makuru, sezvo kugoverwa kwakafanana kwakakosha kuti mashandiro ashande zvakanaka.
IV. Sei Uchifanira Kusarudza Simba reVET?
Mumunda wemasero emafuta uye mamwe mashandisirwo emagetsi emagetsi anoenderana nekupisa kwakanyanya, VET Energy, ichishandisa ruzivo rwayo rwekudyara nekuvandudza muzvinhu zvakagadzirwa nekabhoni, yakagadzira sisitimu yakazara yezvigadzirwa zvegraphite felt nezvinhu zvakasanganiswa zvinofukidza mamiriro akasiyana-siyana ekushandisa, zvichipa mhinduro dzakagadzirirwa mhando dzakasiyana dzemasero emafuta. Mhinduro dzeVET Energy dzakashandiswa zvakanyanya mumatekinoroji akasiyana-siyana, kusanganisira mapuroton exchange membrane fuel cells uye ma solid oxide fuel cells, uye dzakawedzerwa uye dzakasimbiswa mumasisitimu akakura akadai semabhatiri anoyerera. Kana uri kutsvaga mukana wekushandisa wegraphite yakanzwapamwe nezvinhu zvine chekuita nekabhoni mumasisitimu emagetsi, kana kuti muchida kuwedzera kuvandudza maitiro aripo uye mashandiro, ndapota inzwa wakasununguka kutibata kuti tikurukure uye tishande pamwe chete kukurudzira kuvandudzwa kwetekinoroji ye fuel cell yechizvarwa chinotevera.
