The importance of proton transport can be seen in the significant advancements made in hydrogen fuel cell technology. One of the most successful fuel cell types, the proton exchange membrane fuel cell (PEMFC), has been commercialized for use in both residential and transportation applications . This success is due in part to the high-power density and efficiency of PEM-FCs. Almost all commercial PEMFCs employ a Nafion-based proton exchange membrane . However, Nafion membranes require appropriate hydration to operate because Nafion is not an intrinsic proton conducting material. If the hydration level is too low, the proton conductivity drops precipitously and if the hydration level is too high, water will condense in the membrane, a condition known as flooding, which also stops the membrane from functioning. This means that Nafion-based PEMFCs can only operate at low temperatures (< 80 • C) and require expensive and complicated water management hardware. Consequently, there is a need for materials that facilitate low-humidity or even anhydrous proton transport , which will facilitate higher temperature operation, remove the requirement for water management hardware, increase electrode kinetics and decrease CO poisoning of the anode catalyst .
