摘要： Flow fields comprising a set of fluid distribution channels may be employed in fuel cells for purposes of distributing fluid reactants to an electrochemically active area of the fuel cell. Water management and reactant distribution may be improved by increasing pressure gradients between adjacent channels. Such pressure gradients may be increased by engineering the channels such that the resistance to reactant flow differs along the length of adjacent channels.

摘要： Methods and apparatus for processing flexible graphite sheet material involve patterning the material, on at least one major surface, prior to further processing of the material such as densification, lamination, folding or shaping into three-dimensional structures. For densification and lamination, the patterning is selected to facilitate the removal of air from the flexible graphite sheet material during the densification and lamination process. For folding or shaping, the patterning is selected to render the graphite sheet material more flexible. In some embodiments, methods for increasing the through-plane conductivity of flexible graphite sheet material are employed. Integrated heat removal devices include sheets of graphite material that have been selectively patterned in different regions to impart desirable localized properties to the material prior to it being shaped or formed into an integrated heat removal device. Coatings and/or resin impregnation can also be used to impart desirable properties to the material or device.
