Preparation of Polybenzimidazole-Based Membranes and Their Potential Applications in the Fuel Cell System
Various polybenzimidazole (PBI)-based ion-exchange films were prepared and thoroughly characterized by Fourier transform infrared (FT-IR) spectroscopy, proton conductivity, and water uptake for possible use as fuel cell membranes. Upon the increase in the flexibility of the PBI-based polymer films (e.g., poly(oxyphenylene benzimidazole) (OPBI) and sulfonated OPBI (s-OPBI)), the membranes exhibi...
متن کاملHigh-temperature polybenzimidazole-based membranes
Polybenzimidazole (PBI)-based high-temperature proton exchange membranes (PEMs) offer many advantages that aid in a simplified fuel cell system design. Such benefits include high resistance to fuel impurities (most notably carbon monoxide), fast electrode kinetics, and simplified water and thermal management due to operational temperatures above 120 ◦C.[1] As a result of its intrinsic physicoch...
متن کاملAn ultra-microporous organic polymer for high performance carbon dioxide capture and separation.
Rational design concepts were used to prepare a novel porous benzimidazole-linked polymer (BILP-101) in a simple one-pot reaction. BILP-101 has exhibited ultra-microporosity (0.54 nm), very high CO2 uptake (∼1 mmol g(-1), 4 wt%, 0.15 bar/298 K) and exceptional CO2/N2 selectivity of 80 (298 K), which results in remarkable working capacity and regenerability for CO2 capture applications.
متن کاملImproving the Proton Conductivity and Antibacterial Properties of Sulfonated Polybenzimidazole/ZnO/Cellulose with Surface Functionalized Cellulose/ZnO Bionanocomposites
New bionanocomposite proton exchange membranes were prepared from sulfonated polybenzimidazole (s-PBI) and various amounts of sulfonated ZnO/cellulose nanohybrids (ZnO/cellulose-SO3H). The use of ZnO/cellulose-SO3H compensates for the decrease in ion exchange capacity of membranes observed when non-sulfonated nano-fillers are utilized. The strong –SO3H/–SO<su...

Polymer blending is used to modify or improve the dimensional and thermal stability of any two different polymers or copolymers. In this study, both sulfonated polybenzimidazole homopolymer (MS-p-PBI 100) and sulfonat...
