Single-wall carbon nanotube supports for portable direct methanol fuel cells

Article Abstract:

Single-wall and multiwall carbon nanotunes are employed as carbon supports in direct methanol fuel cells (DMFC) and examined to probe the influence of carbon support on the overall performance of DFMC. Single-wall carbon nanotubes when employed as support for anchoring the electrocatalyst particles in the anode and cathode sides of membrane electrode assembly (MEA) exhibited enhancement in the power density of a single stack DFMC.

Highly dispersed Pt catalysts on single-walled carbon nanotubes and their role in methanol oxidation

Article Abstract:

Well-dispersed Pt catalysts with very light utilization efficiencies for fuel cell reactions are prepared by ethylene glycol reduction on polymer-wrapped single-walled carbon nanotubes (SWCNTs). The catalyst dispersion has facilitated the diffusion of reactant species, which in turn has resulted in higher methanol oxidation currents and more positive potentials for oxygen reduction.

Boosting fuel cell performance with a semiconductor photocatalyst: TiO2/Pt-Ru Hybrid catalyst for methanol oxidation

Article Abstract:

A hybrid carbon fiber electrode (CFE) consisting of TiO2 semiconductor photocatalyst and Pt-Ru catalyst to boost the performance of direct methanol fuel cells is developed. TiO2 improves the performance of the Pt-Ru catalyst in dark, indicating possible surface area improvement or diminished poisoning effects.
