The present invention provides an electrically-conductive resin composition for a porous fuel cell bipolar plate capable of forming a porous fuel cell bipolar plate having superior absorption of water produced as well as limited elution of impurities. The layer of metamorphic substance prevents conductive materials constituting electrical connection means formed on the inner wall of the hole from dispersing over a surface of the substrate or permeating into the substrate. The composition can also include a growth medium. The global topology includes each of several active VCs within the network and each of several IP subnets configured on the nodes coupled by the network. Each class is assigned a detector that is implemented by a weighted combination of weak classifiers such that all of the detectors are based on a common ensemble of weak classifiers. A hydrophobic gas-penetrating layer is disposed under the hydrophilic gas-blocking layer.
