摘要: In this chapter, the requirements of a high-performance catalyst layer are examined in order to understand ways which structure might degrade with operation. The formation oxide species on surface platinum is its role both oxygen reduction and setting equilibrium state as function pH potential. Models dissolution subsequent migration through cell reviewed, along an analysis experimental studies aimed at determining evolution particle-size distributions operation fuel cell. mechanism corrosion carbon supports also examined, specifically under off-design points such reveral localized starvation. Implications for material development future modeling needs reviewed.
