The existence of perfluorocarbons (PFCs) not related to the traditional anode effect in industrial cells has been documented for a wide range of technologies. To experience the phenomenon in the laboratory, a system with more than one anode was designed. The setup consists of two separate chambers made out of a single cylindrical block of graphite, which also acts as the joint cathode. Each chamber has its own electrolyte, reference electrode and anode, and the anodes are connected in parallel. The system use a power supply to provide the necessary current and an electronic load to elevate the potentials to industrial levels as well as directing the current to a particular compartment, thus changing the anodic potential. The anodic potential governs which reactions that thermodynamically can happen, making it possible to simulate industrial low cell voltage PFC. Gas analysis can be employed to detect the anodic reaction products.
