AB - The present invention relates to a GDL for PEMfuel cells formed by a macroporous substrate layer (MPS)
and a microporous carbon layer (MPL), the MPS being
formed by carbon fibers and plant fibers, wherein the
plant fibers mainly comprise esparto fibers. Likewise, the
procedure for manufacturing the GDLs is provided, which
comprises: a) Generation of a paper-carbon pulp, using
esparto plant fibers, b) Filtering; c) Homogenization; d)
Cold pressing and compaction of the paper-carbon film;
e) Curing the paper-carbon film at room temperature for
a minimum period of 12 hours, f) Generation of the MPS
by thermal treatment of the cured paper-carbon film at
temperatures not exceeding 1,050°C; g) Obtaining the
MPL layer; h) Application of a 2% perfluoroexane aqueous solution to the GDL obtained and subsequent curing
process at 100-150 °C for 10-20 minutes.
