Kev ntsuas thaj tsam thaj tsam. … Kom meej meej, thaj tsam ntawm electrochemically active deg sawv cev cheeb tsam ntawm cov khoom siv electrode uas nkag tau rau cov electrolyte uas yog siv rau kev them nqi thiab/los yog cia.

Koj pom thaj chaw electrochemical ua haujlwm li cas?

ECSA=QH/ (mpt x 210 x 10^-6); qhov twg, 'QH' yog tag nrho cov nqi ntsig txog H + adsorption ntawm thaj chaw ncov ntawm hydrogen adsorption / desorption; 'mpt' yog lub zog loj ntawm Pt catalyst (gm^2) ntawm GCE. 1.

ECSA yog dab tsi hauv roj cell?

Lub electrochemically active nto cheeb tsam(ECSA) yog ib qho tseem ceeb parameter thaum soj ntsuam thiab tsim electrodes rau roj hlwb. Muaj ntau txoj hauv kev los txiav txim siab ECSA ntawm polymer electrolyte membrane roj hlwb ob leeg hauv thiab ex situ.

ECSA catalyst yog dab tsi?

Electrochemical thaj chaw thiab kev siv catalyst yog qhov tseem ceeb ntawm kev ntsuas kev ua haujlwm rau catalyst thiab membrane electrode los ua ke (MEA) cov neeg tsim khoom thiab cov chaw tsim khoom. Cov txheej txheem rau kev txiav txim siab thaj chaw electrochemical (ECSA) ntawm cov roj cell electrodes los ntawm CV tsom xam tau siv ntau xyoo lawm.

Koj paub li cas yog tias CV muaj ob txheej txheej txheem?

Coj qhov dav tam sim no ntawm CV (hauv amps, xaiv ib qho taw qhia hauv CV qhov twg tsis muaj txheej txheem faradaic tshwm sim) thiab faib qhov ntawd los ntawm tus lej scan ntawm CV (V / s). Amps yog Coulombs/s faib los ntawm Volts/s=Coulombs / Volt uas yog Farrads.
