Effect of the exchange current density (j 0 ) on the the current density (j): j(t) = j 0 {exp [-  nF  /RT] - exp[(1-  )nF  /RT]}

j(t) = j 0 { exp [-  nF  /RT] - exp[(1-  )nF  /RT] } represented together with the forward and backward components Variation of j as a function of j 0 :

j 0 = A  = 0.5

j 0 = A  = 0.5

j 0 = A  =
