The anodic oxidation of formic acid has been investigated on platinum black electrodes in 5 N sulfuric acid. The data presented pertain to the activation controlled process under approximately steady state conditions at four temperatures between 25° and 90 °C. Tafel plots appear to have significant slopes, and the correlation of these slopes with experimentally measured electrode coverages supports the hypothesis of two distinct electrochemical oxidation mechanisms, advanced by other workers.
