Ngokuqhubekayoumlinganiselo woxinaniso lwemethanolibaluleke kakhulu kwimveliso yeseli ye-methanol fuel cell (DMFC), ingakumbi kuphuculo lokwenziwa kombane ngokufanelekileyo kunye nokwandisa ubomi bebhetri. Ukusebenza kokuvelisa amandla kumiselwa yireyithi yokusabela kwi-oxidation ye-methanol kumphezulu we-electrode, kwaye ireyithi yokusabela kwe-oxidation iphenjelelwa kukuxinana kwemethanol kakhulu.
Ukudityaniswa okuchanekileyo kwesisombululo semethanol yimfuneko yokusebenza kakuhle kwe-electrochemical reaction kunye nokudluliselwa kwe-electron egudileyo. Ngaphaya koko, iqinisekisa amandla ombane aphezulu kunye noxinaniso lwangoku, ekugqibeleni iphucule ukusebenza kakuhle koguqulo lwamandla. Ukukhutshwa kwamandla okuzinzileyo sesinye isizathu solawulo oluchanekileyo loxinzelelo lwemethanol. Ukwahluka kwemveliso yamandla sisiphumo sokuguquguquka koxinzelelo lwemethanol. Lonnmeterimitha yoxinaniso lwemethanolsesinye sezona gawuji zibalaseleyo zokuqonda ugxininiso lwemethanol ngexesha lokwenyani, ingakumbi kumgca wemveliso ozenzekelayo.
Iindlela zoMlinganiso weMethanol Concentration
No.1 Umlinganiselo woxinaniso
Aimitha yobuninzi bolweloisebenzisa unxulumano phakathi koxinaniso kunye nokuxinana kwesisombululo semethanol ukuqonda uqwalaselo oluqhubekayo lokuxinana kwemethanol. Ukufaneleka kwale ndlela kuxhomekeke kumlinganiselo ozinzileyo kunye nokuchaneka okuphezulu ngokuhambelana nemodeli yobudlelwane boxinaniso loxinaniso-ubushushu obusetwe ngaphambili. Qhagamshelana neenjineli zethu ukuze ufumane ezinye iiparamitha malunga neimitha yoxinano lwebhetrinomgca.
No.2 Indlela yokuNqanda
Ukuxinwa kwesisombululo semethanol kunokuchazwa ngumgca ongaphakathii-densitometerokanyeirefractometerngokusekwe kumahluko kwizalathisi ze-refractive phakathi kwe-methanol kunye ne-solvent yayo. Nangona kulula ukuyisebenzisa kwaye inika impendulo ekhawulezayo, isalathiso se-refractive siyahluka kumaqondo obushushu ahlukeneyo. Ngoko ke, ukulungiswa kweqondo lokushisa kuyimfuneko kumlinganiselo ochanekileyo.
No.3 Near-Infrared Spectroscopy (NIR)
I-spectrometer ekufutshane ne-infrared isebenza kwimodeli yobudlelwane bobungakanani phakathi kokufunxa kunye noxinzelelo lwe-methanol, isenza iskena sexesha langempela lesisombululo semethanol kunye nokulinganisa ukufunxa kubude obuthile bamaza. Ngokubanzi, i-methanol ibonisa iincopho ezithile zokufunxa ngaphakathi kwingingqi ye-infrared spectral ekufutshane.
No.4 i-Electrochemical Sensor
Inzwa ye-electrochemical ibona ukugxilwa kwe-methanol ngotshintsho lwangoku okanye olunokuthi lube nokunciphisa i-oxidation phezu komhlaba. Ivumela ukubeka iliso kwi-intanethi ngexesha lokwenyani ngexabiso eliphantsi lokuphendula ngokukhawuleza, ubuntununtunu obuphezulu kunye nokukhetha okukhulu. Nangona kunjalo, uzinzo kunye nobomi busengozini yongcoliseko kunye notshintsho lwemo engqongileyo. Isebenza ngokuqhelekileyo kuphela ngokulinganisa rhoqo kunye nokutshintshwa.
No.5 Fuel Cell
Uxinzelelo lwe-methanol luyakwazi ukugqithiswa ukusuka kumbane okhoyo kunye noveliso lombane ngeseli ekhethekileyo yamafutha, apho ukusabela kwe-oxidation kwenzeka ukujonga ukugxila kwemethanol kunye nokusebenzisa izixhobo.
Qhagamshelana neenjineli zethu ukufumana isisombululo somlinganiselo wobuchwephesha woxinaniso lwemethanol. Cela ikowuti yasimahla ngoku!
