Abstract

Uniform mixtures of fuel together with air can be supplied to both cathode and anode of fuel cells and generate power as proposed before. The necessary condition for this to happen is an asymmetry in the catalytic properties of the electrodes. A few experimental works have demonstrated this over the last 5 years and a basic theoretical analysis has been recently presented. We here report on I-V measurements done using mixtures of H2+O2+Ar as well as using mixture of CH4+O2+Ar and C2H4+O2+Ar. The solid electrolyte used is Y2O3 stabilized ZrO2. For some of the low temperature measurements Nafion 117 is used as the SE. This allows for a better understanding of the catalytic activity of the electrodes.
