MATHEMATICAL ANALYSIS AND EXPERIMENTAL RESULTS OF APPLYING ENHANCED-SURFACE-AREA PACKED-BED ELECTRODES IN ELECTROGENERATIVE SULFUR DIOXIDE OXIDATION
The results of applying enhanced-surface-area packed-bed (ESAP) electrodes in electrogenerative SO2/O2 cells are reported to illustrate their utility and potential applications. Mathematical analysis with parameters pertinent to the experimental conditions shows that all electrocatalyst sites in these electrodes are expected to be uniformly utilized for electrochemical SO2 oxidation. Experimental results showed that ESAP electrodes (1 mgPt/cm2) could provide at least 5 times higher SO2 conversion at given cell voltages than graphite sheet electrodes(1.5 mgPt/cm2).
