Abstract

A thin, flat, and porous carbon gas diffusion electrode having a side in contact with a supply of gas and a side in contact with an electrolyte, comprises a pyrolysis product of a composite of an organic aerogel or xerogel and a reinforcing skeleton consisting at least in part of organic material. The porosity of the carbon gas diffusion electrode according to the invention can be regulated at will while the surface of the electrode is smooth.
