The need to design low-cost adsorbents for the detoxification of industrial effluents has been a growing concern for most environmental researchers. So modelling of experimental data from adsorption processes is a very important means of predicting the mechanisms of various adsorption systems. Therefore, this paper presents an overall review of the applications of adsorption isotherms, the use of linear regression analysis, nonlinear regression analysis, and error functions for optimum adsorption data analysis.

The key to address the cost issue of polymer electrolyte membrane fuel cells (PEMFCs) lies on reducing Pt amount employed in cathode catalyst layers (CCLs). In past decades, researchers focus on developing series of alloy and core–shell electrocatalysts with high oxygen reduction reaction activity in order to alleviate the low Pt loading caused performance loss. However, it is noted that the concentration polarization loss resulting from the cathode oxygen transport plays a more important role as the Pt loading decreases, especially the local oxygen transport through the ultrathin ionomer film covering on Pt surface. This paper reviews the nanomorphology of the ultrathin perfluorinated sulfonic acid ionomer film in CCLs, as well as the local oxygen transport mechanism and the corresponding effects on fuel cell performance in low Pt PEMFCs. In addition, both the detailed local oxygen transport properties in carbon black‐supported Pt membrane electrode assemblies (MEAs) and high surface carbon‐supported MEAs are summarized. Subsequently, numerous innovative strategies and effective approaches of reducing the local oxygen transport resistance are introduced. The new insights proposed in this paper have important implications for enhancing local oxygen transport and designing high‐performance fuel cell electrodes.
