In recent years Direct Formic Acid Fuel Cells (DFAFCs) have attracted interest as alternative energy sources. Formic acid is abundant as it is a by-product of multiple industrial processes and it can be obtained from the oxidation of biomass. In addition, due to the capacity to use high concentrations of fuel, DFAFCs are effective at room temperature which makes it an ideal candidate for portable energy applications and it has a low permeability, which clearly distinguishes it from other Proton Exchange Membrane Fuel Cells (PEMFCs). This allows it to generate higher power densities ~160 mW/cm² at room temperature outperforming other liquid fuel cells such as Direct Methanol Fuel Cells (DMFCs) with power densities of ~50 mW/cm². However, a few obstacles prevents its optimization, first the behaviour and loading of the catalytic material and second the proper selectivity of the proton exchange membrane. For this the synthesis of a new catalytic material has been carried out, by the deposition of palladium Nano-particles in graphene oxide and reduced graphene oxide, obtained by the electrochemical exfoliation of graphite in order to introduce doping agents in the graphene matrix such as nitrogen, sulphur and boron and with it improve its catalytically activity and reduce catalyst loadings in DFAFCs. To address the second obstacle hindering DFAFCs, a comparative analysis of proton exchange membranes of the Nafion family was carried out and the intrinsic conductivity, dimensional stability as well as its operational temperature was observed for its use in formic acid fuel cells. From the results obtained a high performance was observed using a polytetrafluoroethylene reinforce membrane (Nafion XL) at room temperature. The membrane displayed a higher resistance to dimensional change when exposed to a wide range of formic acid concentrations, showing a maximum increase of 10% of its planar dimension while other membranes such as Nafion 117,115 and 211 had a significantly higher increase up to 45%. Results indicated that a reinforced membrane could be more suitable for DFAFCs, not only by possessing a higher dimensional stability but also due to it having a higher hydrophobicity due to the reinforcement and the lower content of sulfonic groups present in the copolymer. These changes would address the dehydration of the membrane, a factor substantially affecting the performance of the cell.
