Abstract
The present disclosure relates to a porous transport layer for a cathode comprising carbon fibers and polymer resin, an intermediate substrate layer disposed on the lower substrate layer and containing carbon fibers, and a microporous layer disposed on the intermediate substrate layer. The lower substrate layer may comprise a first lower substrate layer, and a second lower substrate layer disposed on the first lower substrate layer and having an average density lower than an average density of the first lower substrate layer. The intermediate substrate layer may be disposed on the second lower substrate layer. A water electrolysis cell may comprise the porous transport layer and the cathode.
