Finite-length warburg
WebJul 13, 2024 · The finite-length Warburg impedance (Z W) is a mathematical expression derived from Fick's second law of diffusion and describes diffusion of electroactive particles through a finite diffusion distance. Two parameters manly comprise the mathematical expression of Z W: oxygen diffusion time constant and oxygen transport resistance.
