N2 - This chapter discusses performance degradation of low temperature fuel cell catalysts due to the influence of dynamic operation conditions. The aim is to highlight fundamental studies on the chemical degradation of the catalyst and summarize recent results. A short overview of catalyst ageing mechanisms is given, then techniques for their investigation are introduced. The chapter then focuses on the methodology and results of identical location transmission electron microscopy (IL-TEM), as originally developed in our laboratory. © 2012
