Passive direct formic acid microfabricated fuel cells
This paper reports on microscale silicon-based direct formic acid fuel cells (Si-DFAFCs) in which the fuel and the oxidant are supplied to the electrodes in a passive manner. Passive delivery of fuel and oxidant eliminates the need for ancillary components and associated parasitic losses. In this Si-DFAFC, an aqueous solution of formic acid is in direct contact with a Pdor Pt-based anode and a ...
متن کاملAn effective Pd-Ni(2)P/C anode catalyst for direct formic acid fuel cells.
The direct formic acid fuel cell is an emerging energy conversion device for which palladium is considered as the state-of-the-art anode catalyst. In this communication, we show that the activity and stability of palladium for formic acid oxidation can be significantly enhanced using nickel phosphide (Ni(2)P) nanoparticles as a cocatalyst. X-ray photoelectron spectroscopy (XPS) reveals a strong...
متن کاملNanocrystalline intermetallics on mesoporous carbon for direct formic acid fuel cell anodes.
Shape- and size-controlled supported metal and intermetallic nanocrystallites are of increasing interest because of their catalytic and electrocatalytic properties. In particular, intermetallics PtX (X = Bi, Pb, Pd, Ru) are very attractive because of their high activity as fuel-cell anode catalysts for formic acid or methanol oxidation. These are normally synthesized using high-temperature tech...
متن کاملA Microscale Vapor-fed Formic Acid Fuel Cell
A silicon-based microfabricated fuel cell running on formic acid vapor as a fuel has been developed to provide on-chip power for MEMS devices, without using any ancillary devices such as heaters, water management, air pumps, etc. As a demonstration instrument, an integrated silicon-based membrane electrode assembly and fuel evaporative structure was packaged in a plastic package to test the vap...
متن کاملPalladium nanoparticles supported on carbon black powder as an effective anodic catalyst for application in a direct glucose alkaline fuel cell
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...
