A review is presented of work in the area of polymer electrolyte membranes for fuel cell operation at temperatures exceeding 100 °C. Development of these electrolytes will permit fuel cell operation with greatly increased tolerance to carbon monoxide, and greatly reduced humidification requirements. The focus is on the electrolyte membranes based on basic polymers doped with acids, i.e., phosphoric acid-doped polybenzimidazole. The key properties of these membranes including conductivity, permeability, and mechanical strength are reviewed, as well as fuel cell performance under various operating conditions.
