Origin of performance degradation of palladium-based direct formic acid fuel cells

Enhanced catalytic performance of carbon supported palladium nanoparticles by in-situ synthesis for formic acid electrooxidation

“…A peak at approx. 34°, which is attributed to the PdO reflection, is also observed for the Pd/C-C catalyst; a similar result was reported for the Pd catalyst exposed in air for a period of time [32].…”

Recent Development of Pd-Based Electrocatalysts for Proton Exchange Membrane Fuel Cells

“…1.0 V vs. RHE or more. Ren et al [125] found that the Pd oxides/hydrous oxides (POHOs) play a crucial role in promoting better performance and minimizing performance degradation of the Pd-based DFAFCs. The intrinsic presence or introduction of Pd oxides/hydrous oxides during catalysis of formic acid oxidation was found to promote elimination of poisoning species, thereby leading to a better performance of DFAFCs.…”

Formic acid electrooxidation catalyzed by Pd/SmOx-C hybrid catalyst in fuel cells

“…Formic acid electrooxidation has attracted great attention due to the development of direct formic acid fuel cells (DFAFCs) as well as for understanding the fundamental theory of electro-catalytic reactions [1][2][3]. Both Pt-based and Pd-based catalysts have been widely used as the anodic catalysts for formic acid electrooxidation [4][5][6][7].…”
