Abstract
- The homogeneous/heterogeneous catalyst combination of VO<superscript>2+</superscript> in anolyte with Pd/C at the anode is first introduced in a formic acid fuel cell to enhance HCOOH electrooxidation. The VO<superscript>2+</superscript>/Pd catalyst combination establishes a stepwise reaction pathway involving HCOOH dehydrogenation to form V<superscript>3+</superscript> from VO<superscript>2+</superscript> reduction and subsequent V<superscript>3+</superscript> electrooxidation to regain VO<superscript>2+</superscript>. The fuel cell with the VO<superscript>2+</superscript>/Pd combination presents a peak power density of 341.3 mW cm<superscript>−2</superscript> and stable power density higher than 30 mW cm<superscript>−2</superscript>.
