Abstract
In the present study, polybenzimidazole (PBI) polymer which has a great importance in polymer
electrolyte membrane (PEM) research was synthesized via the solution polycondensation method,
under various synthesis conditions to put forward the effect of the synthesis parameters on the
properties of the synthesized polymer and consequently to the quality of the prepared polymer
electrolyte membrane. The synthesized polymers were characterized in terms of their chemical
structure, thermal degradation behaviour, and molecular weight by Fourier transform infrared
spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (
1
H NMR), thermogravimetric
analysis (TGA). The Mechanical properties, acid-doping level capacity, proton conductivity, and
fuel cell performances of the produced phosphoric acid doped PBI were investigated. The
Thermogravimetric analyses showed that the synthesized polymers have an excellent thermal
stability up to 580o
C. Mechanical analyses revealed that the mechanical strength of the PBI
membranes increases with increasing molecular weight of the polymer and reaches the maximum
value of 17.65 MPa. The maximum power density was observed to be 48.6 mW/cm2
of the fuel
cell test at 120o
C.
