Iqhubekekaumlinganiselo woxinzelelo lwe-methanolIbaluleke kakhulu kwimveliso ye-direct methanol fuel cell (DMFC), ingakumbi ekuphuculeni ukusebenza kakuhle kokuveliswa kombane kunye nobomi bebhetri obongezelelekileyo. Ukusebenza kakuhle kokuveliswa kombane kuxhomekeka kwizinga lokusabela kwe-oxidation ye-methanol kumphezulu we-electrode, kwaye izinga lokusabela kwe-oxidation lichaphazeleka kakhulu kukuxinana kwe-methanol.
Ukuhlanganiswa ngokuchanekileyo kwesisombululo se-methanol kuyimfuneko yempendulo ye-electrochemical esebenzayo kunye nokudluliselwa kwe-electron okubushelelezi. Ngaphezu koko, kuqinisekisa i-output voltage ephezulu kunye noxinano lwangoku, ekugqibeleni kuphucula ukusebenza kakuhle kokuguqulwa kwamandla. Ukuphuma kwamandla okuzinzileyo sesinye isizathu sokulawula ngokuchanekileyo uxinano lwe-methanol. Ukuphuma kwamandla okutshintshatshintsha sisiphumo sokuguquguquka koxinano lwe-methanol. I-Lonnmeterimitha yoxinzelelo lwe-methanolyenye yezona ndlela zibalaseleyo zokulinganisa i-methanol ngexesha langempela, ingakumbi ebaluleke kakhulu kumgca wemveliso ozenzekelayo.
Iindlela zokulinganisa ukuxinana kweMethanol
Isilinganiso sobuninzi beNombolo 1
Aimitha yoxinano lwezinto ezilweloisebenzisa ulwalamano phakathi koxinano kunye noxinano lwesisombululo se-methanol ukuze kuqinisekiswe ukubekwa esweni okuqhubekayo koxinano lwe-methanol. Iingenelo zale ndlela zikwimilinganiselo ezinzileyo kunye nokuchaneka okuphezulu ngokwemodeli yobudlelwane boxinano-uxinano-ubushushu obucwangcisiweyo. Nxibelelana neenjineli zethu ukuze ufumane ezinye iiparameter malungaimitha yoxinano lwebhetrinomgca.
Indlela yokuHlaziya yeNombolo 2
Uxinzelelo lwesisombululo se-methanol lunokufunyanwa ngomgca ophakathii-densitometerokanyei-refractometerngokusekelwe kumahluko kwiindices zokuchasana phakathi kwe-methanol kunye nesinyibilikisi sayo. Nangona kulula ukuyisebenzisa kwaye inika impendulo ekhawulezayo, i-refractive index iyahluka kumaqondo obushushu ahlukeneyo. Ke ngoko, ukulungiswa kobushushu kuyimfuneko ukuze kulinganiswe ngokuchanekileyo.
Inombolo 3: I-Near-Infrared Spectroscopy (NIR)
I-spectrometer ekufutshane ne-infrared isebenza kwimodeli yobudlelwane obuphakathi kokufunxwa kunye noxinzelelo lwe-methanol, yenza iskena se-methanol ngexesha langempela kwaye ilinganise ukufunxwa kwii-wavelengths ezithile. Ngokubanzi, i-methanol ibonisa iincopho ezithile zokufunxwa ngaphakathi kommandla we-spectral ekufutshane ne-infrared.
Inombolo 4 Inzwa ye-Electrochemical
I-sensor ye-electrochemical ibona uxinzelelo lwe-methanol ngotshintsho ekuncipheni kwe-oxidation yangoku okanye enokubakho kumphezulu. Ivumela ukujonga i-intanethi ngexesha langempela ngexabiso eliphantsi ukuze kuphendulwe ngokukhawuleza, uvakalelo oluphezulu kunye nokukhetha okukhulu. Nangona kunjalo, uzinzo kunye nobomi buchaphazeleka kungcoliseko kunye notshintsho lokusingqongileyo. Isebenza ngokwesiqhelo kuphela ngokulinganisa rhoqo kunye nokutshintshwa.
Iseli yepetroli yeNombolo 5
Uxinzelelo lwe-Methanol lunokuqondwa ukusuka kumbane kunye nombane oveliswa yiseli ekhethekileyo yamafutha, apho ii-oxidation reactions zenzeka ukujonga uxinano lwe-methanol kwaye zisebenzisa izixhobo.
Nxibelelana neenjineli zethu ukuze ufumane isisombululo sobungcali sokulinganisa i-methanol concentration. Cela ikowuteshini yasimahla ngoku!
