3. Kinetic
Kinetic (Kinetika) membahas tentang laju reaksi dan mekanisme terjadinya reaksi

4. Overpotential Hydrogen
Adanya gerakan ion (kinetik) yang lambat menyebabkan potensial yang menyimpang dari nilai Nernst Pada Hydrogen : 2H+ + 2e- = H2

5. Kinetic Overpotential Hydrogen
Mass Transfer-Controlled Reaction- Concentration Overpotential

6. Kinetic Overpotential Hydrogen
Interfacial Reaction Rate Control- Activation Overpotential

7. Kinetic Overpotential Hydrogen

8. Kinetic Overpotential Hydrogen
Difusi H3O+ dari Bulk Solution menuju double layer
H3O+ melewati Double Layer
Dehidrasi ion
H3O H2O + e
a) Electrochemical
H3O+ + M + e-  M-H + H2O (pelepasan ion)
b) Pembentukan molekul-molekul Hydrogen
2 M-H  2M + H2

9. Kinetic Overpotential Hydrogen
Desorpsi gas H2 dari elektroda
Difusi gas H2 keluar/menjauhi elektroda
