Performance Analysis of MEAs with Different Ion Exchange Capacity Ionomers by a Simplified Analysis Method

抄録

The effects of the ion exchange capacity (IEC), of the perfluorosulfonic acid polymers, on the performance of PEFC has been investigated quantitatively by a simplified analysis method. It was determined that the IEC of the membrane influences the mass transfer overpotential of the oxygen reduction reaction (ORR). Whereas, it was determined that the IEC of the catalyst coating ionomer influences the activation overpotential of the ORR.
