AB  - Over the last 30 years, a variety of polymers have been developed and investigated as potential replacements for Nafion®. As with Nafion®, the majority of investigated polymers are poly sulfonic acids though alternate ionomers based on phosphonic acid6, and benzimidazole8 are also considered. As a class, sulfonated aromatic polymers tend to be easier to synthesize and thus less expensive than Nafion®. Polymers synthesized from less expensive strong acid vinyl monomers such as 2-acrylamido-2-methylpropane sulfonic acid (AMPS) are also considered and indeed this monomer is utilized within this paper. An additional benefit of this monomer is that it is amenable to photo induced polymerization which we herein present as a relatively uncomplicated method for preparing PEMs with nevertheless quite high proton conductivity. Further tests are planned to determine the real applicability of such polymers for use in PEMFCs.

AB  - Proton exchange membranes (PEM) for low temperature fuel cells must ensure high proton conductivity and effective separation of anode and cathode under operating conditions. DuPont’s sulfonic acid fluoropolymer Nafion has seen commercial success, though high cost limits wider acceptance. As lower cost options, polymers based on 2-acrylamido-2-methylpropane sulfonic acid (AMPS) are also investigated. Swelling of polyAMPS (PAMPS) is however a shortcoming, although this may be reduced by improved crosslinking. Both commercial and novel crosslinkers were tested with AMPS by dissolving with photoinitiator in water and photo-curing. To facilitate conductivity measurements, polymers were constrained within a porous membrane. In contrast to commercial crosslinkers, where high percentages are required to improve conductivity, our new acrylamide based crosslinkers showed excellent results at lower concentrations. Thus 5 wt% crosslinker provided membranes with 2.5 times the conductivity of Nafion. The novel polymers were then coated onto asymmetric membranes increasing proton-conductivity and reducing methanol crossover.
