If the associated calculated cumulative carbon mass losses are examined (Fig. 11.3 la) and C corrosion-driven Pt surface area decrease (Fig. 11.31b) for the 25 pm case calculated, it can be concluded that PEM side-chain degradation mitigates the cathode carbon corrosion This is because of the calculated decrease of PEM proton conductivity (from the PEM degradation model), which contributes to decreasing the proton reverse current (from the cathode to the anode) and thus mitigates the carbon corrosion in the cathode. These results provide some ejqrlanation of some experimental data showing that cathode carbon support corrodes less with PEMs that have some facility to degrade their conductivity. ... 

The positive electrode is a necessary and key component in a lead-acid battery. It determines the battery s performance in terms of energy density and efficiency, power density, and cycle life. This chapter provided detailed descriptions of electrode design, materials and structures, fabrication, electrode process mechanisms, performance degradation, and degradation mitigation strategies.
