Biological fuel cells and their applications
One type of genuine fuel cell that does hold promise in the long-term is the biological fuel cell. Unlike conventional fuel cells, which employ hydrogen, ethanol and methanol as fuel, biological fuelExpand

A semi-empirical model of the direct methanol fuel cell performance. Part I. Model development and verification
A model equation is developed to predict the cell voltage versus current density response of a liquid feed direct methanol fuel cell (DMFC). The equation is based on a semi-empirical approach inExpand

An X-ray photoelectron spectroscopic study on the effect of Ru and Sn additions to platinised carbons
Electro-catalytic oxidation of methanol is known to be promoted on Pt-Ru and Pt-Sn surfaces. Whilst Ru addition to Pt has been unambiguously acknowledged to enhance the methanol-oxidation reaction,Expand

Graphitic Carbon as Durable Cathode-Catalyst Support for PEFCs
Long-term deterioration in the performance of PEFCs is attributed largely to reduction in active area of the platinum catalyst at cathode, usually caused by carbon-support corrosion. It is found thatExpand
