Emkhakheni we-Electrochemistry, ukusebenza kahle kanye nokusebenza kwamaseli we-electrochemical kubaluleke kakhulu. Phakathi kwezinto ezahlukahlukene ezibangela ukusebenza kahle, ama-anome amile adlala indima ebalulekile. Lezi zinto ezenziwa ngama-electrodes zingaphezu nje kwezinto nje; Bangumgogodla wesistimu ye-electrochemical, ethonya ama-kinetics okusabela jikelele, ukuqina kanye nokuphila kweseli.
Ama-anode amilezenzelwe ukuhlala endaweni ehleliwe ngesikhathi senqubo ye-electrochemical, ukuhlinzeka ngeplatifomu ezinzile zokuphendula kwe-oxidation okwenzeka e-anode. Lokhu kuzinza kubalulekile ekugcineni ukusebenza okungaguquki ngokuhamba kwesikhathi. Ngokungafani nama-anodo ashukumisayo noma ajikelezayo, ama-anode emile aqeda ubunzima obuhambisana nenhlangano yemishini, okwenza ukwakheka kanye nokusebenza kwama-electrochemical cell kube lula.
Enye yezinzuzo eziphambili ze-anodes emile yikhono lazo lokukhulisa ukusebenza kahle kwe-electrochemical. Ngokunikeza indawo ezinzile yokudluliswa kwe-elektroni, ama-anome ajwayelekile akhuthaza i-oxidation of ama-acractants, ngaleyo ndlela akhuphule ubukhulu bamanje kanye nokwenza ngcono ukusebenza kweseli okuphelele. Lokhu kubaluleke kakhulu kwizicelo ezifana ne-electrolysis, amaseli kaphethiloli, namabhethri, lapho ukukhulisa ukusebenza kahle kokuphendula kwe-electrochemical kungathinta kakhulu ukuphuma kwamandla nezindleko zokusebenza.
Ngokwengeziwe, ama-anome amile aklanywe ngokusebenzisa izinto ezahlukahlukene ukwenza ngcono ukusebenza kwazo. Izinto ezijwayelekile zifaka i-graphite, iplatinamu, kanye nama-oxides wensimbi ahlukahlukene, ngalinye linezakhiwo ezihlukile ezingathuthukisa ukusabela kwe-electrochemical. Isibonelo, ama-anode ama-graphite ayaziwa ngokusebenza kwawo okuhle nokuqina kwamakhemikhali, okwenza babe nelungele izinhlelo eziningi. Ngakolunye uhlangothi, ama-anode weplatinamu ajwayele ukusetshenziswa kumaseli we-performer asebenza kakhulu ngenxa yezakhiwo zawo ezinhle kakhulu ze-catalytic.
Idizayini ye-anode yesiteshi nayo idlala indima ebalulekile ekusebenzeni kwayo. Izici ezinjengendawo engaphezulu, impama, ne-morphology zingathinta kakhulu ukusebenza kwe-electrochemical. Indawo enkulu engaphezulu ivumela amasayithi asebenzayo ukuthi asabele, kanti isakhiwo se-porous singathuthukisa ukuthuthwa kwezinto ezibonakalayo, ukuqinisekisa ukuthi ama-eckants afinyelela i-anode kahle. Abaphenyi bahlola njalo imiklamo emisha nezinto zokwakha ukuze zithuthukise ukusebenza kwama-anode ezimisiwe bese zicindezela imikhawulo yobuchwepheshe be-electrochemical.
Ngaphezu kokwenza ngcono ukusebenza kahle, ama-anode emile asiza ukunweba impilo yamaseli we-electrochemical futhi athuthukise ukuqina kweseli. Ngokuhlinzeka ngesiteji esingaguquki futhi esithembekile sokuphendula, basiza ukunciphisa izindaba ezinjengokuwohloka kuka-electrode kanye nokuhambahamba, okungadala ukusebenza kwehle ngokuhamba kwesikhathi. Lokhu kuzinza kubaluleke kakhulu kwizicelo zezimboni, lapho izindleko zokuphumula nezindawo zokugcina ziphezulu.
Njengoba isidingo sezixazululo ezisebenza kahle ziqhubeka zikhula, ukubaluleka kwama-anode amile kumaseli we-electrochemical awakwazi ukwenziwa ngaphansi. Amandla abo okukhulisa ukusebenza kahle kokuphendula, athuthukise ukuqina, futhi anwebise impilo yezinhlelo ze-electrochemical abenze babe yingxenye ebalulekile ekuthuthukiseni ubuchwepheshe obuthuthukile. Ukusuka emandleni avuselelekayo ezixazululweni zokugcina amandla, ama-anode stationary avela indlela yekusasa elizinzile futhi elisebenzayo.
Ngokufigqiwe,ama-anode amilengempela bangumgogodla wamaseli we-electrochemical afanele. Idizayini yabo, ukukhethwa kwezinto ezibonakalayo, nokuqina kokusebenza kuyizinto ezibalulekile ezithonya ukusebenza kwezinhlelo eziningi ze-electrochemical. Njengoba ucwaningo nentuthuko kulo mkhakha kuyaqhubeka ukuqhubekisela phambili, singalindela ukubona izixazululo ezintsha ezitholwa yizakhiwo ezihlukile zama-anode ezimisiwe, ubuchwepheshe be-electrochemical ezithuthukayo kanye nezicelo zalo empilweni yethu yansuku zonke.
