[ What is claimed is:] [1.]1. A plate assembly for use adjacent to membrane electrode assemblies in a liquid fuel cell, the assembly comprising:a) at least one substantially planar and vertically oriented plate having a first layer of carbon/metal composite overlaying a second layer of hydrophilic polymer or copolymer;b) a plurality of conductive elements extending from at least one surface of the plate, providing electrical communication through the plate;c) an air inlet port and an air exit port formed on the plate in locations to establish an air flow path; andd) a surface, directly or indirectly contiguous with the substantially planar and vertically oriented plate, located at the air exit port, whereby liquid is withdrawn from the air flow path.
