Carbon nanofiber-based active layers for fuel cell cathodes – preparation and characterization

Formation of noble-shaped carbon nanostructures

“…For direct alcohol fuel cells (DAFCs), the use of 1D-CNMs as the metal catalyst support was reported to greatly enhance the electro-catalytic activity for alcohol oxidation, as well as its ability to protect from the degradation caused by carbon monoxide poisoning. This is accomplished via its noble hosting geometry for the metal catalyst particles [8][9][10][11][12][13]. In general, the enhanced surface area of the metal catalyst through size reduction of the metal catalyst allows for increased number of active sites for catalytic performance.…”

Helical nanocoiled and microcoiled carbon fibers as effective catalyst supports for electrooxidation of methanol

“…In particular, in developing the high performance electrocatalysts of direct alcohol fuel cells (DAFCs), the use of 1D carbon materials as support could enhance the electrocatalytic activity of alcohol oxidation, which is closely related to their geometrical microstructure and desirable hosting structure for noble metal catalyst particles [4][5][6], as well as high protection ability for carbon monoxide poisoning [7][8][9]. However, in recent years, few works have been carried out on carbon nanofibers (CNFs) as fuel cell electrocatalyst support, but tests in DAFC systems of CNFs showed promising results [7,10,11]. The morphology and microstructure of carbon-based support materials, however, have great impact on their electrochemical properties.…”

Catalyst Preparation by Electroless Plating and Hydrogen Direct Reduction Methods: Practical Application for a High Cell Performance PEFC

“…Although the electroless plating method has various potential advantages, the application of electroless plating tactics has not been studied sufficiently for fuel cell catalysts [7,[15][16][17]. Electroless plating is a method of depositing metal ions from a plating solution with a reducing agent.…”
