Analyzing Fuel Cell Electrode Corrosion by Electrochemical QCM-D

Polymer Electrolyte Membrane Fuel Cells (PEMFCs) are promising for use in applications such as cars, laptops and stationary applications. However, corrosion of the electrodes shortens their lifetime, and better understanding of these processes is necessary to improve PEMFCs and make them a realistic alternative as a source of electricity. Here, QCM-D combined with electrochemistry was used to investigate corrosion of PEMFC electrodes.
