Abstract

Fuel cell performance using formic acid as a fuel has been examined with various anode catalysts. Also the optimum conditions were investigated for the high performance of the direct formic acid fuel cell(DFAFC). The change in the flow rate of formic acid had only a slight effect on the performance of fuel cell. The best performance was shown at 9 M formic acid. Power density increased about 10 mW/cm2 with an increase in the loading of Pt-Ru black catalyst from 4 mg·Pt/cm2 to 8 mg·Pt/cm2. The highest power density was 36.6 mW/cm2 with a Pt-Ru black catalyst of 8 mg·Pt/cm2 and 9 M formic acid feed. Finally the open circuit potential(OCP) was the highest for Pt-Pd catalyst at about 0.820 V, including that Pt-Pd was the most suitable catalyst for oxidation of formic acid.
