| Proton exchange membrane (PEM) fuel cells that operate at high temperatures (>150 °C) are desirable for a number of reasons, such as higher tolerance of the anode to CO poisoning,increased catalyst efficiency, and easier thermal management.Fuel cells that operate at lower temperatures generally require water for proton transport. However, at higher temperatures, a polymer must be designed that strongly binds to water or has a different medium of proton transport. Polybenzimidazole (PBI) doped with H3PO4 has been established as a good polymer system for use in proton exchange membrane (PEM) fuel cells at high operation temperature and low humidity conditions.The only true requirement of the polymer in this system is to have a heteroatom that is capable of hydrogen bonding to H3PO4,which allows for a high uptake. |
