The PBI membranes are easily doped with strong inorganic acid to get proton conductivity. They perform as a PEFC membrane at high temperature (120 similar to 200degreesC) under non-humidified condition. The PBI derivatives are very promising materials for proton exchange membrane fuel cell (PEMFC) and direct methanol fuel cell (DMFC).
