Abstract: 
The aim of this paper is the characterization of a carbon felt (Le Carbone
Lorraine, RVC 4002) to be used as three-dimensional electrode. A wide
group of very different techniques were used in the physical and structural
characterization of this material. Both, structural (porosity, mean pore
radius, specific surface area, tortuosity) and physical properties
(permeability, electrical resistance) were determined by using mercury
porosimetry, adsorption isotherm analysis, a filamentary analog procedure
and liquid permeametry (pressure drop method). The results obtained from
the modelling of the hydrodynamic behaviour, from previous work, were
also applied here. The carbon felt studied was found to have a porosity
around 0.98, a specific surface area of 22100-22700 m-1, 2.7 10-3 W m
electrical resistivity and a tortuosity between 5 and 6. The comparison of
these results with those found in the literature for other similar materials,
used as three-dimensional electrodes, highlights the attractions of this carbon felt as a three-dimensional electrode.
