Abstract
Microporous composites adopted for electrolytic applications, e.g., as cathodes in the electrolysis of sodium chloride, are comprised of a regular, homogeneous and consolidated microporous deposit of monodispersed carbon fibers on a perforated rigid support substrate therefor, said carbon fibers having a distribution by length such that the mean length of at least 80% of the individual fibers, plus or minus 20%, corresponds to the mean length of said fibers.
