Okuqhubekayoukulinganiswa kokuhlushwa kwe-methanolKubalulekile ekukhiqizweni kwe-direct methanol fuel cell (DMFC), ikakhulukazi ekuthuthukiseni ukusebenza kahle kokukhiqizwa kwamandla kanye nokuphila kwebhethri okwandayo. Ukusebenza kahle kokukhiqizwa kwamandla kunqunywa izinga lokusabela kwe-oxidation le-methanol ebusweni be-electrode, futhi izinga lokusabela kwe-oxidation lithonywa kakhulu ukuhlushwa kwe-methanol.
Ukuhlanganiswa okunembile kwesixazululo se-methanol kuyimfuneko yokusabela kwe-electrochemical okusebenzayo kanye nokudluliswa kwama-electron okubushelelezi. Ngaphezu kwalokho, kuqinisekisa i-voltage ephezulu yokuphuma kanye nobuningi bamanje, ekugcineni kuthuthukisa ukusebenza kahle kokuguqulwa kwamandla. Ukukhishwa kwamandla okuzinzile kungenye yezizathu zokulawula okunembile kokuhlushwa kwe-methanol. Ukukhishwa kwamandla okushintshashintshayo kuwumphumela wokushintshashintsha kokuhlushwa kwe-methanol. I-Lonnmeterimitha yokuhlushwa kwe-methanolingenye yezindlela ezinhle kakhulu zokulinganisa ukuhlushwa kwe-methanol ngesikhathi sangempela, okubaluleke kakhulu emugqeni wokukhiqiza okuzenzakalelayo.
Izindlela Zokulinganisa Ukuhlushwa kwe-Methanol
Isilinganiso Sobuningi No.1
Aimitha yobuningi bezinto eziwuketsheziisebenzisa ubudlelwano phakathi kobuningi kanye nokuhlushwa kwesisombululo se-methanol ukuze kuqashwe njalo ukuhlushwa kwe-methanol. Izinzuzo zale ndlela zisesilinganisweni esizinzile kanye nokunemba okuphezulu ngokuya ngemodeli yobudlelwano bobukhulu-ukuhlushwa-nokushisa esethiwe. Xhumana nonjiniyela bethu ukuthola eminye imingcele mayelanaimitha yobuningi bebhethriemugqeni.
Indlela Yokubukeza Eyesi-2
Ukuhlushwa kwesisombululo se-methanol kunganqunywa ngokufaka i-inlinei-densitometernomai-refractometerngokusekelwe ekwehlukeni kwezinkomba zokubuyisa phakathi kwe-methanol kanye nesinyibilikisi sayo. Nakuba kulula ukuyisebenzisa futhi inikeza impendulo esheshayo, inkomba yokubuyisa iyahlukahluka emazingeni okushisa ahlukene. Ngakho-ke, ukulungiswa kwezinga lokushisa kuyadingeka ukuze kulinganiswe kahle.
Inombolo 3: I-Near-Infrared Spectroscopy (NIR)
I-spectrometer eseduze kwe-infrared isebenza kumodeli yobudlelwano obunobungako phakathi kokumuncwa kanye nokuhlushwa kwe-methanol, yenza ukuskena kwesikhathi sangempela kwesisombululo se-methanol futhi ilinganise ukumuncwa kuma-wavelength athile. Ngokuvamile, i-methanol ikhombisa iziqongo ezithile zokumuncwa ngaphakathi kwesifunda se-spectral esiseduze kwe-infrared.
Inzwa ye-Electrochemical No.4
Inzwa ye-electrochemical ithola ukuhlushwa kwe-methanol ngokushintsha kokuncipha kwamanje noma okungenzeka kwe-oxidation ebusweni. Ivumela ukuqapha kwe-inthanethi ngesikhathi sangempela ngezindleko eziphansi ukuze kuphendulwe ngokushesha, ukuzwela okuphezulu kanye nokukhetha okukhulu. Noma kunjalo, ukuzinza kanye nesikhathi sokuphila kungathinteka ekungcoleni kanye nezinguquko zemvelo. Isebenza ngokujwayelekile kuphela ngokulinganisa okuvamile kanye nokufakwa esikhundleni.
Iseli likaphethiloli elingu-5
Ukuhlushwa kwe-Methanol kungenziwa kusukela kumandla kagesi kanye ne-voltage ekhiqizwa yi-fuel cell ekhethekile, lapho kwenzeka khona ukusabela kwe-oxidation ukuze kuqashwe ukuhlushwa kwe-methanol futhi kusetshenziswe izinsiza.
Xhumana nonjiniyela bethu ukuze uthole isisombululo sobungcweti sokulinganisa ukuhlushwa kwe-methanol. Cela ikhotheshini yamahhala manje!
