The definitive version of the work is published in Finite Elements in International Journal of Hydrogen Energy, vol 43(27), pp 12337-12345A facile method has been suggested for the preparation of poly [2,20-(p-oxydiphenylene)-5,50-benzimidazole] (OPBI) membrane that comprises of dense and porous layers for high temperature proton exchange membrane fuel cells (HT-PEMFCs). The porosity as well as the asymmetry of the membrane is formed by the use of component solvent at steadily increasing temperatures. This approach needs not to use any porogen, whereas the resultant asymmetric OPBI membrane indicates an improved phosphoric acid (PA) doping level together with mechanical strength. For instance, the PA doping level of the asymmetric OPBI membrane is almost twice as much as that of the homogenous dense OPBI membrane. The conductivity of asymmetric OPBI arrived at 0.072 S cm(sup)-1 at 180 degrees C. The membrane electrode assembly (MEA) based on the asymmetric OPBI demonstrated an exceptional fuel cell functionality with a peak power density of 393 mW cm(sup)-2 at 160 degrees C under anhydrous conditions.enHT-PEMFCPolybenzimidazole membranePhosphoric acid dopingArticleOu, T., Chen, H., Hu, B., Zheng, H., Li, W., & Wang, Y.
