| Abstract | The potential-current characteristics of a H2/O2 polymer electrolyte membrane fuel cell using H2SO4 or H3PO4 doped PBI were studied for the first time. The conditions involved in the doping of PBI with sulphuric acid or phosphoric acid and the preparation of a membrane electrode assembly (MEA) using these membranes were determined. The potential-current fuel-cell characteristics of MEAs using H2SO4-doped PBI were compared to those of MEAs using Nafion 117. The effects of membrane doping and of drying times on the fuel-cell performances of MEAs based on PBI doped with sulphuric acid in various conditions were determined. It was shown that MEAs based on H2SO4 doped PBI and non-humidified exhibited higher fuel-cell characteristics than MEAs based on Nafion 17. The fuel-cell characteristics of MEAs based on phosphoric-acid-doped PBI exhibited high performances at 185 oC even with fuelled with hydrogen containing 3% CO. |
