The objective of the current report is to compare the performance of poly(phenylene) based anion
exchange membranes in an alkaline direct methanol fuel cell when platinum cathode catalysts are
replaced with non-platinum cathode catalysts. In a KOH-free methanol fuel, we show that a less
expensive non-Pt cathode catalyst (derived from Fe-Aminoantipyrine, Fe-AAPyr using Generations 1 and
2 sacrificial silica supports) provide better or comparable performance to commercial Pt cathode
catalysts. The peak power density, current density and open circuit voltage of Fe-AAPyr-G-1 in 1 M
methanol at 80 C are 2.78 mWcm2
, 19.1 mAcm2 and 0.7 V respectively. In a direct methanol fuel cell
utilizing KOH in the fuel feed, the non-Pt catalyst shows promising peak power density of 52 mWcm2
with the Fe-AAPyr-G-2 cathode catalyst, comparable to a commercial Pt catalyst.
