“…In order to overcome these challenges, formate salt (formic acid in alkaline media) is used. Formate is easily handled, stable, low toxic and low cost, and has a theoretical cell voltage of 1.45 V, which is greater than that DLFCs employing alcohol fuels [5,7].…”

PdAu/C electrocatalysts in different atomic ratios (90:10, 80:20, 70:30, and 50:50) supported on Vulcan XC72 carbon were evaluated toward formate oxidation in alkaline media. The materials were prepared by the borohydride process. X-ray diffraction (XRD) patterns of PdAu materials showed peak characteristic of Pd and Au face-centered-cubic (fcc) structures while transmission electron micrographs (TEM) showed the nanoparticles with particle size between 4 and 10 nm for all electrocatalysts. Experiments considering single cell suggested the PdAu/C (90:10) and PdAu/C (80:20) as promisors for formate oxidation. The best result obtained was attributed to the presence of Au in small quantities that contributes to the formate adsorption.

“…However, the mechanism produces CO 2 , which contributes to the greenhouse emissions. But the most advantage of using formate is that this fuel could be formatted from CO 2, and many studies contemplates interesting results in which the CO 2 is converted in formic acid/formate [2,7,[12][13][14][15].…”

The miniaturization of electro-mechanical devices, and the resulting need for micro-power generation (milliwatts to watts) with low weight, long life devices, has led to the recent development of the field of micro-scale combustion and power generation. The primary objective of this new field is to leverage the high energy density of fuels, specifically liquid hydrocarbon fuels relative to batteries and all other energy storage devices other than nuclear fission, fusion or decay. Some brief scaling arguments are given in this work, and more detailed efforts are referred. A brief introduction to several of the fabrication techniques is presented in this work. Hydrogen-based and some preliminary specialty fuel micro-fuel cells have been successfully developed, and there is a need to develop reliable reformers (or direct conversion fuel cells) for liquid hydrocarbons so that the fuel cells become competitive with the batteries. In this work, the technological issues related to micro-scale combustion and the development of thermochemical devices for power generation will be discussed. Some of the systems currently being developed will be presented, ongoing critical study issues under investigation, and other potential areas of development discussed. Comments regarding the opportunities and limitations of each of the techniques are also presented where applicable.

“…Of late, formate oxidation on Pd in alkaline fuel cells has been studied [24][25][26][27][28][29] and according to previous study reported by Haan et al, formate shows relatively fast oxidation kinetics. Therefore, we assume that formate could compensate slow kinetics of ethanol oxidation, resulting in relative high current density of fuel mixture at low overpotential and finally high power density.…”
