    摘要: A water transport plate assembly that is useful in fuel cells includes at least one hydrophilic article such as a flow field layer. A method of making the hydrophilic article includes establishing a hydrophilicity of the article by including a plurality of graphite particles (112) having a particular physical characteristic that imparts the hydrophilicity to the article. In one disclosed example, the selected graphite particles (112) have a wettability ratio of a hydrophilic surface area to a total surface area that is sufficient to make the article hydrophilic. In a disclosed example, the wettability ratio is more than 0.10. In a disclosed example, the graphite particles are selected based upon a percentage of prismatic surface area of the total surface area.

    摘要: In one example, a fuel cell utilizes a non-carbonized, non-graphitized porous polymer water transport plate having a water permeability of less than 30×10−17 m2. The water transport plate is part of a fuel cell that employs an evaporative cooling loop. In one example, the water transport plate has a bubble pressure of less than 5 psig. The water transport plate is less costly and easier to manufacture.
