Solid acid membranes for high temperature (¿140° C) proton exchange membrane fuel cells
Journal of Power Sources, 2005Proton exchange membrane fuel cells (PEMFCs) are an exciting clean energy technology for power delivery for a range of devices from automotive applications through to portable digital equipment. Current technology for PEMFCs is limited by its inability to operate at high temperatures which is particularly desirable for automotive applications.

Abstract A cross-linked network is obtained by an end-group cross-linkable PBI (E-PBI) and 4,4′-diglycidyl (3,3′,5,5′-tetramethylbiphenyl) epoxy resin (TMBP). The formation of the network is proved by FT-IR and gel fraction test. Then, high temperature proton exchange membranes are constructed by incorporating the cross-linked network into poly(2,2′-(

A New Type of High Temperature Membrane for Proton Exchange Membrane Fuel Cells
ASME 2006 Fourth International Conference on Fuel Cell Science, Engineering and Technology, Parts A and B, 2006The proton exchange membrane (PEM) fuel cell operated at high temperature is advantageous than the current low temperature PEM fuel cell, in that high temperature operation promotes electro-catalytic reaction, reduces the carbon monoxide poisoning, and possibly eliminates methanol crossover in Direct Methanol Fuel Cell (DMFC).

High Temperature Polymers for Proton Exchange Membrane Fuel Cells
2014Novel proton exchange membranes (PEMs) were investigated that show potential for operating at higher temperatures in both direct methanol (DMFC) and H2/air PEM fuel cells. The need for thermally stable polymers immediately suggests the possibility of heterocyclic polymers bearing appropriate ion conducting sites.
