Electrospun nano fibers solution properties

The PBI/PBI-PBz-f (thickness 75 pm) composite membrane containing 20 wt% of the PBI-PBz electrospun nano-fiber, of which 10 wt % was the PBz crosslinker, was doped with a phosphoric acid aqueous solution followed by MEA preparation to perform high-temperature fuel cell tests. The phosphoric acid doping level and proton conductivity, membrane mechanical properties, and fuel cell performance of this PBI/PBI-PBz-f composite are listed in Tables 12.3, 12.4, and 12.5, respectively. The data for neat PBI are given for comparison. The PBI/PBI-PBz-f composite membrane showed higher PAdop and a, higher mechanical strength and strain at break, and better fuel cell performance than the neat-PBI membrane. Compared to the hydrophobic porous PTFE film, the... [Pg.268]
