Abstract: This paper reports on a single alkaline exchange membrane direct formate fuel cell (AEM DFFC) consisting of a carbon-supported palladium catalyst at the anode, a quaternized polysulfone membrane, and a non-precious Fe–Co catalyst at the cathode. It is demonstrated that the AEM DFFC yields a peak power density of 130mWcm−2 with 5M potassium formate (HCOOK) at 80°C. It is further shown that with the addition of KOH to the anolyte, the peak power density rises to as high as 250mWcm−2 at the same operating temperature. In addition, the AEM DFFC was also tested at 100mAcm−2 for more than 130h and no significant degradation in performance is found. The results reported in this work suggest that formate salt (HCOOM, M+=Na+ or K+) is a potential fuel for alkaline-type direct liquid fuel cells.
