Electrochemical formation of carbon film

Electrolytic synthesis Electric power 0.46 39.0 43.0 2.5 V (based on experimental data) 

A simple corrosion test by using an aqueous FeCl3 solution as well as an anodic polarization measurement in a sulfuric acid solution shows their high corrosion resistance. 

The obtained carbon-coated metal showed the advantageous features for a fuel cell separator and a current collector of a Li-ion secondary battery. 

Carbon free (Fossil fuel is not used) Low energy consumption Low cost 

On-site production Available under unstable electric power supply conditions

The electrochemical formation of carbon film can be achieved by either the anodic oxidation of 3 ion or the cathodic reduction of COj ion [3-5]. The principle of each reaction is shown in Figure 7.1.5a,b.
