This article outlines recent progress in electrocatalysts and membranes for polymer electrolyte fuel cells (PEFCs), as well as various evaluation methods for these materials, including characterization of structural and physical properties, commonly used electrochemical techniques, and advanced in situ methods. Particular attention has been paid towards matters that require consideration when using specific techniques and the uniqueness of particular evaluation methods.
