8 Half – cell performance of Carbon Felt Samples The apparent rate constant for each felt is reported as the average of the apparent rate constants calculated from the current densities of 100 mA cm-2 or less, (Figure 8.4). This current density range was chosen to reduce the influence of mass transport limitations, which occur at the higher current densities. Figure 8.4: Apparent rate constant comparison between values calculated from cyclic voltammetry and polarization curves. a) GFE and C100 felt samples, b) G100 felt samples. Apparent rate constants calculated using Equation 2. The rate constants calculated from polarization curve data for the GFE and C100 felts, thermally treated and untreated are in excellent agreement with the previously reported values calculated from cyclic voltammetry reported in Chapter 7. This confirms that the analysis of the cyclic voltammetry data using the assumed void distribution modelling was accurate. However, there was a noticeable increase in the calculated rate constant for G100 from polarization curve measurements relative to those from cyclic voltammetry. G100 clearly had much larger peak separation during cyclic voltammetry than the GFE and C100, therefore the difference in measurement methods is likely responsible for the different in the recorded apparent rate constant. The higher rate constants recorded during polarization curve measurements in the half-cell can be explained by improved wetting, which may due to use of the peristaltic pump. 119PDF Image | Electron Transfer Kinetics in Redox Flow Batteries
