A 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 کاملPassive 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 کاملRole of Water in Formic Acid Decomposition
Formic acid decomposes primarily to CO and H2 0 in the gas phase, but to CO, and H, in the aqueous phase. Ab-initio quantum chemical calculations were performed, using Hartree-Fock and density functional methods, to seek an explanation for this behavior. The effect of water on the two decomposition pathways and on the isomerization of formic acid was determined. The transition state structures ...
متن کاملHydrogen generation from formic acid decomposition with a ruthenium catalyst promoted by functionalized ionic liquids.
Hydrogen has attracted increasing attention as an important alternative secondary energy resource particularly when combined with fuel-cell technology, which may play a very significant role in power generation in the future. Currently most H2 is produced industrially by methane or alcohol reforming and by the water–gas-shift reaction at high temperatures. However, special purification steps ar...
متن کاملCatalytic ammonia decomposition: COx-free hydrogen production for fuel cell applications
Catalytic decomposition of ammonia has been investigated as a method to produce hydrogen for fuel cell applications. The absence of any undesirable by-products (unlike, e.g., COx , formed during reforming of hydrocarbons and alcohols) makes this process an ideal source of hydrogen for fuel cells. In this study a variety of supported metal catalysts have been studied. Supported Ru catalysts were...
