Despite over a century of study and decades of intensive research, few fuel cell products have appeared on the market. The major inhibitor to mass commercialisation is cost. H2/air alkaline fuel cells (AFCs) containing KOH(aq) electrolyte promise the lowest cost devices, with the ability to use non-Pt catalysts. The fundamental problem with AFCs is that the KOH(aq) electrolyte reacts with CO2 (...

The ability to accurately measure separate in situ anode and cathode overpotentials and impedance responses is still a source of debate when investigating fuel cells of planar configuration containing < 100 μm thickness solid electrolytes and when using the common three electrode arrangement. The results obtained in this study indicate that the overpotentials and impedances of the anode and cat...

High-Performance Alkaline Direct Methanol Fuel Cell using a Nitrogen-Postdoped Anode Report Title A commercial PtRu/C catalyst postdoped with nitrogen demonstrates a significantly higher performance (?10–20?% improvement) in the anode of an alkaline direct methanol fuel cell than an unmodified commercial PtRu/C catalyst control. The enhanced performance shown herein is attributed at least parti...
