Increasing demand for clean energy power generation is a direct result of the rapid depletion fossil fuel reserves, volatility commodity prices, and environmental damage caused by burning fuels. Fuel cell vehicles, portable supplies, stationary stations, submarines are just some applications where proton exchange membrane (PEM) cells prominent technology generation. PEM have several advantages over conventional sources, including higher density, lower emissions, operating temperature, efficiency, noiseless operation, ease design, operation. The catalyst layer electrode assembly discussed in this paper as vital part cell. Along with that, platinum (Pt)-based catalyst, carbon support, nafion ionomer found often degrade. Catalyst growth, agglomeration, Pt loss, migration, active site contamination, other microscopic processes all considered degradation process. Employing experimental numerical research focus on enhancing material properties was suggested possible solution to understanding problem degradation. Ultimately, review aims prevent high costs associated replacing catalysts through recommendations provided study.

Considerable research efforts have been made to investigate the degradation mechanisms of various components proton exchange membrane fuel cells (PEMFCs). However, understanding large active area PEMFCs under automotive operating conditions remains an important focus. In this study, unsteady 3D computational fluid dynamics (CFD) model in combination with 1D models for carbon corrosion, platinum dissolution and hydrogen peroxide production provides detailed insights into potential a PEMFC. Typical phenomena are influenced by local factors such as potential, temperature humidity. These internal states cannot be easily captured conventional measurement methods. The simulation driving cycle high dynamic load at two humidification intake air showed significant variations. Although concentration anode catalyst layer decreases humidity 25%, Pt/C decomposition cathode increases. Low lead strong temporal fluctuations water content membrane, which increases risk mechanical fatigue. Despite increased observed humidity, improved homogeneity potentials within layers mitigates ionomer degradation.
