A three-dimensional fine mesh, with optimized flow paths, exhibits the best performance in commercialized fuel cell electric vehicles, but the manufacturing cost is significantly high. To achieve high performance at a lower cost, the possibility of using a combination of commercially available screen meshes was investigated. The overlapped screen meshes should provide improved mass transport similar to a 3-D fine mesh. By using an optimized combination of screen meshes (200 and 100 mesh) and gasket thickness (150 mu m thinner than the mesh flow field), an improvement in oxygen mass transport was achieved. The suggested combination shows a lower oxygen gain (0.030 V) than a single mesh (0.050 V) and a conventional single serpentine flow field (0.150 V).
