Abstract (en)
[origin: WO2005013398A2] The invention concerns a porous structure characterized in that it comprises a porous carbon fabric matrix (15), said porous matrix being delimited at one of its surfaces (17, 21) by a sealing layer (19, 23) made of an element selected among carbon fibers, carbon nanotubes, glassy carbon, said sealing layer being bound to the porous matrix by carbon-carbon bonds. The invention also concerns a method for making such porous structures. The invention is applicable to fuel cells and heat exchangers.
