CROSSED-RIDGE SEALING SURFACE

摘要

Fluid leakage restriction in multi-layered systems that contain fluids such as electrochemical cell devices (12) with sealing surfaces (10) defining patterns of ridges forming concentric rings surrounding through apertures within the surfaces require a new surface design for use of a potential through aperture site. A crossed-ridge sealing surface (10) is comprised of a first plurality of aligned ridges (48) and a second plurality of aligned ridges (50) that crosses the first plurality of aligned ridges to define sealing cells (52) that surround the existing through apertures (28) and potential through aperture sites, so that one sealing surface design may enhance fluid leakage restriction for a variety of actual and potential through apertures.
