The chapter begins with a brief introduction of the importance and role of electrocatalysts in fuel cells. The following sections discuss the current state-of-the-art for noble metal electrocatalysts in polymer electrolyte fuel cells (PEFCs) along with an examination of recent developments in various noble metal (Pt, Pd, Au, Ag, Ir, Ru) electrocatalysts used in anode and cathode of a PEFC. Various 0D, 1D, 2D, and 3D nanostructured morphologies of electrocatalysts are scrutinized. Different factors responsible for influencing and manipulating the electrocatalytic response and the stability of electrocatalysts are also discussed. The need and scope for recycling of precious metal electrocatalysts are examined and finally expected future trends are deliberated.
