Reply to the letter of P. Zoltowski “Remarks on “Determination of hydrogen absorption isotherm and diffusion coefficient in Pd81Pt19 alloy” [F. Vigier et al., J. Electroanal. Chem. 588 (2006) 32]”

The remarks of Zoltowski [P. Zoltowski, J. Electroanal. Chem., Remarks on “Determination of hydrogen absorption isotherm and diffusion coefficient in Pd81Pt19 alloy” [F. Vigier et al., J. Electroanal. Chem. 588 (2006) 32]] refer to hydrogen electrosorption isotherm and the diffusion coefficient of hydrogen DH in Pd81Pt19 alloy. However, they do not contain any quantitative analysis of data being the subject of criticism. Discussion presented below shows that in some points we do not agree and in others there was no difference in our views.
