Kinetické vlastnosti kladných elektrod se základem MnO2 s různými dopujícími přísadami
Vognar, J. ; Brudná, S. ; Novák, V. ; Vondrák, Jiří ; Sedlaříková, M.
The present study aims at evaluating the activity of such manganise oxide-based electrocatalysts toward the ORR. Electrochemical measurement was realized by method of cyclic voltametry on RDE in three electrodes circuit.

Novák, V. ; Brudná, S. ; Vognar, J. ; Barath, P. ; Vondrák, Jiří ; Sedlaříková, M. ; Kazelle, J.
The fuel cells belongs to group of derivaces in which is internal energy of the fuel changed into the electrical energy.The electrochemical reaction is representanted by marked peak in half wave potential area.By that method can be found out activity of the electrode which determine potential of inflection point or potential of half-wave.
