Variety, Features and Shapes of Working electrodes
| Variety of Working Electrodes | Features and Applications |
| Platinum electrode (PTE) | Conventional electrode, which has hydrogen adsorptive wave, used for H2O2 and oxides detection |
| Gold electrode (AUE) | Conventional electrode, which has no hydrogen adsorption wave, used for thiols detection |
| Glassy carbon electrode (GCE) | Chemically stable electrode despite its relatively large over-potentials of oxygen and hydrogen evolutions |
| Silver electrode (AGE) | For cyanide and sulfide detection |
| Carbon paste electrode (CPE) | Mixed with enzyme etc. to make modified electrodes |
| Nickel electrode (NIE) | Chemically modified to detect amino acids |
| Palladium electrode (PDE) | Used to study the process of adsorption and desorption of hydrogen |
| Plastic formed carbon electrode (PFCE) | Its highly-oriented graphite edge is exposed to the surface with cost effective, similar feature of HOPG |
