An overview of the uses of polymers with intrinsic microporosity as binders for electrocatalysis

Le résumé fourni par la source

This comprehensive review provides a detailed analysis of the potential of polymers with intrinsic microporosity (PIMs) as specialized binders for electrochemical applications. The quest for improved fuel cell and electrolyzer performance has driven extensive research on binders. Early investigations focused on conventional binders, aiming to enhance mechanical properties and adhesion. However, limitations in mass transport prompted the search for novel materials with superior gas permeability, driving interest in PIMs. Analyzing recent advancements and insights presented in the literature, we elucidate the distinct advantages offered by PIMs, such as chemical stability and enhanced gas permeability. The latter attribute is crucial for a binder in electrochemical devices, allowing efficient transport of reactants (e.g., hydrogen, oxygen) to active sites within the catalyst layers, significantly improving device efficiency and reaction rates. By synthesizing and assessing key research findings, this review aims to pave the way for future advancements in PIM-based binders for electrochemical applications, filling a notable gap in the existing literature.
