In this review, we have examined the different models for polymer-electrolyte fuel cells operating with hydrogen. The major focus has been on transport of the various species within the fuel cell. The different regions of the fuel cell were examined, and their modeling methodologies and equations were elucidated. In particular, the 1-D fuel-cell sandwich was discussed thoroughly because it is t...

In this chapter research trends followed by various scientific groups for the development of polymeric membranes have been described and reviewed. Most notably, the developments made at Ballard Advanced Materials (BAM) and some of their results are discussed. In general three different approaches have been followed worldwide by various research groups for the development and conception of alter...

Interpenetrating Polymer Network Electrolyte In article number 2213469, Hsisheng Teng and co-workers demonstrate a robust solid-state lithium battery with synergy between O-based F-based polymer networks, which overpowers liquid electrolyte batteries in terms of safety performance. This synergistic relationship, combined the creation an anion-aggregate domain, expedites Li+ transport battery.

Polymer solid state electrolytes are actively sought for their potential application in energy storage devices, particularly lithium metal rechargeable batteries. Herein, we report a polymer with high concentration salts as a quasi-solid state electrolyte used for lithium-sulfur cells, which shows an ionic conductivity of 1.6 mS cm(-1) at room temperature. The cycling performance of Li-S batter...

Triblock Polymer Electrolyte In article number 2300425, Anqiang Pan, Zhi Chang, and co-workers construct a triblock polyacrylonitrile/polylactic acid-block-ethylene glycol polymer as skeleton for gel electrolyte, in which the chain structure increased electronegative functional groups extended chains play important roles directing transport of Li+ ions forming compact interface layers.

In a common salt-in-polymer electrolyte, a polymer which has polar groups in the molecular chain is necessary because the polar groups dissolve lithium salt and coordinate cations. Based on the above point of view, polystyrene [PS] that has nonpolar groups is not suitable for the polymer matrix. However, in this PS-based composite polymer-in-salt system, the transport of cations is not by segme...

A Poly (ethylene oxide) based polymer electrolyte impregnated with 2-Mercapto benzimidazole was comprehensively characterized by XRD, UV–visible spectroscopy, FTIR as well as electrochemical impedance spectroscopy. It was found that the crystallization of PEO was dramatically reduced and the ionic conductivity of the electrolyte was increased 4.5 fold by addition of 2-Mercapto benzimidazole. UV...
