Direct alcohol fuel cells (DAFCs) generate electrical power by feeding a liquid fuel directly to an anode, which makes them easier to design as small and lightweight fuel cells. It is well known that methanol is volatile and relatively toxic. Therefore, other alcohols are being considered as alternative fuels. Ethanol is less toxic compared to methanol, and can be easily produced in great quantity by fermentation of sugar containing raw material. Thus, direct ethanol fuel cells (DEFCs) have attracted more and more attention. The use of polyhydric alcohols such as ethylene glycol and glycerol as fuels can be interesting choice because they are less toxic and display relatively high theoretical energy density(5.2 and 5kWh kg-1 for ethylene glycol and glycerol respectively). Pt-based catalysts are recognized as the best electrocatalyst for low temperature fuel cells. However, the limitation of the usage of Pt-based catalysts comes from high cost and limited Pt resources. One effective approach to the cost reduction is to reduce the usage of the Pt catalysts or to replace the Pt catalysts. In the present study, Pd(dba) 2 electrocatalyst has been used for the electrooxidation of different alcohols(ethanol, methanol, ethylene glycol and glycerol) in alkaline media. The Structure of Pd(dba) 2 characterized by X-ray spectroscopy. The electrooxidation of alcohols on Pd(dba) 2 was studied by different electrochemical methods such as; Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS) and chronoamperometry. The onset potential and the specific peak current density of the ethanol, EG and glycerol electrooxidation have shown a notable value for Pd(dba) 2 catalyst compare to conventional catalyst according to CV results. EIS and chronoamperometry electrochemical techniques were used to investigate the stability of Pd(dba) 2 catalyst before and after get 50, 100,150 and 200 CV. The electrochemical impedance spectroscopy studies at different potential reveal that the alcohols electrooxidation on Pd(dba) 2 catalyst is a complex reaction by many different intermediate products. It is shown that before starting of CV the resistance naturally became smaller in values. After 50th cycle, the diameter of the impedance arcs increase, suggesting the organic groups in the catalyst structure prevented from attack of hydroxyl groups and alcohol on the palladium surface. In the higher cycles (after 100th and 150th cycles), Nyquest plots show a smaller value for Rct than 50th cycle in both of potentials. A possible explanation is that with increasing the number of cycle's hydroxyl groups and alcohol adsorbed on the catalyst active sites and anodic reaction became more active. In continue, Pd(dba) 2 poisoning occurs and Rct has been increased after 200th cycle.
