High Temperature Proton Exchange Fuel Cells (HT-PEMFCs)

High temperature proton exchange membrane fuel cells (HTPEMFCs) based on phosphoric acid-doped polybenzimidazole (PBI) have received wide attention over the past decade. As opposed to perfluorosulphonic acid polymers (e.g. Nafion), which only function properly when they are in a highly hydrated state within a limited temperature range (<100 C), phosphoric acid-doped PBI can function at elevated temperatures (100– 200 C) under anhydrous conditions. 

 

 Benifits

  1. Increased kinetics of the oxygen reduction reaction

  2. Greater tolerance of the catalyst to CO

  3. Simplification of the cooling and hydration system

Polybenzimidazole (PBI)

  1. Good thermal stability

  2. Good chemical stability

  3. Good mechanical propertise

  4. Low fuel crossover

  5. High proton conductivity of acid-doped PBI
