摘要：
A fluid distribution element is provided for a fuel cell having a major surface facing a membrane electrode assembly (MEA) and one or more flow channels for transporting gas and liquid to and from the MEA. One or more regions of the major surface are overlaid with a super-hydrophilic corrosion-resistant layer comprising a fluoropolymer. Methods of making such a fluid distribution element are also provided.
