Carbonaceous fuel cell electrode substrate incorporating three-layer separator, and process for preparation thereof |
摘要 |
Disclosed herein is an electrode substrate for fuel cells which comprises a three-layer separator and two porous single or double carbonaceous layers. The separator comprises a carbon plate and two flexible graphite sheets. The porous layer has a number of elongated holes for feeding reactant gases into a fuel cell. The elongated holes are provided near the center of the thickness in the porous single layer or in the interface between the porous double layer. The electrode substrate of the present invention exhibits improved properties, such as mechanical strength, thermal and electric resistances and the like, as a fuel cell electrode substrate. The present invention provides processes for preparation of such an electrode substrate.
