Polybenzimidazole Fuel Cell Technology
2012After approximately 10 years of development, polybenzimidazole (PBI) chemistries and the concomitant manufacturing processes have evolved into commercially produced membrane electrode assemblies (MEAs). PBI MEAs can operate reliably without complex water humidification hardware and are able to run at elevated temperatures of 120–180°C due to the ...

THERMOCHEMISTRY OF POLYBENZIMIDAZOLE FOAMS
1977Abstract : Results are presented of a study of an automatic polybenzimidazole (PBI) polymer. This study included an analysis of the low-boiling, high-boiling, and solid residue fractions resulting from the pyrolysis and nonflaming oxidative degradation of PBI polymer at temperatures up to 1000 deg C.

Charakterisierung von phosphorsäuredotierten Polybenzimidazol-Membranen
2018A polymer electrolyte fuel cell (PEFC) is an energy converter that converts the chemical energy of a fuel directly into electrical energy through electrochemical reactions. Compared to classic PEFCs, high-temperature PEFCs (with operating temperatures between 140-180 °C) have several advantages, such as high carbon monoxide tolerance and easier water ...

Comfort Properties of Polybenzimidazole Fiber
Textile Research Journal, 1984Derivatized polybenzimidazole (PBI) fiber is a unique material that offers a com bination of high performance and improved comfort properties. PBI has excellent thermal and chemical resistance and significantly reduced flame shrinkage; it also possesses good moisture and tactile properties which lead to improved wearer comfort when used in thermal ...
