Improvement of electrocatalytic performance of carbon supported Pd anodic catalyst in direct formic acid fuel cell by ethylenediamine-tetramethylene phosphonic acid

► Pd/C-E catalyst can inhibit the decomposition of formic acid. ► Electrocatalytic stability of the catalyst was improved. ► Pd/C-E catalyst can solve two big probems of DFAFC. ► Electrocatalytic stability of Pd is related to decomposition of formic acid.
