Development of half-cells with sulfonated Pt/Vulcan catalyst for PEM fuel cells

Pd/TiO2-Multiwall Nanotubes toward Electrocatalytic Oxidation of Formic Acid in Acid Media

“…Furthermore, the DFAFCs require less storage, transport and handling cares when compared to hydrogen cells (6,7). Pt is the most commonly used catalyst in fuel cells (8)(9)(10)(11), although its notoriuous disadvantages such as low availability, and electroactive sites poisoning that occur during adsorption of intermediates such as CO (12). Conversely to Pt-based catalysts, those comprising Pd have resulted promising during electrooxidation of formic acid by a more direct route that does not generate CO, which increases the capacity of the catalyst (13).…”
