Palladium nanoparticles supported on carbon black powder (Vulcan XC-72) nanocomposite (Pd/C) are synthesized as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterization of the catalyst is carried out using physical and electrochemical methods. It is observed that Palladium nanoparticles are uniformly dispersed onto the carbon blac...

The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors...

Platinum–tin-containing materials are the most popular catalysts for processes occurring in fuel cells with direct ethanol oxidation. Pulse electrolysis based on electrochemical dispersion of platinum electrodes under influence alternating pulse current an alkaline electrolyte made it possible to introduce tin component into catalyst form a dopant, alloy platinum, and oxide phase evaluate effec...

Crosslinked anion exchange membranes (AEMs) made from poly(vinyl alcohol) (PVA) as a backbone polymer and different approaches to functional group introduction were prepared by means of solution casting with thermal chemical crosslinking. Membrane characterization was performed SEM, FTIR, thermogravimetric analyses. The performance AEMs evaluated water uptake, swelling degree, ion capacity, OH-...

An overview is reported about the history of prevailing direct ethanol fuel cells (DEFCs) as a renewable green source energy. Important features effect of: (1) operating DEFCs in alkaline media, (2) development suitable preparation method or technique catalyst to achieve more favorable dispersion and smaller particle size, (3) employing high surface area supports, (4) combining with another met...

The present work proposes and demonstrates a methodology to capture the effect of operating conditions on ionic conductivity of membranes immersed in alkaline media. Based on reported experimental results for an anion exchange membrane (A-201 by Tokuyama) and a cation exchange membrane (Nafion 211), two novel expressions are developed for the ionic conductivity by incorporating the effects of s...
