    摘要： A sealed assembly is made using sealant including a deformable spacer to control thickness without adversely impacting elasticity and sealing force. Deformable spacers (e.g., elastomer, polyolefin, etc.) are mixed with an elastomeric precursor material and dispensed onto an assembly component, such as a fuel cell bipolar plate, and the remaining component(s) are assembled by pressing against the deformable spacer to ensure a defined seal thickness. The precursor is cured to form a seal that is further compressed to provide an effective sealing force. The deformable spacers control the thickness of a sealed area and allow use of form-in-place sealing processes.

    摘要： A method for forming a hydrolytically-stable hydrophilic coating on a fuel cell flow field plate comprises contacting a flow field plate with a titanium oxide sol to form a titanium oxide layer disposed upon the flow field plate. The coated flow field plate is subsequently contacted with a silicon oxide sol to form a silicon oxide/titanium oxide bilayer disposed upon the flow field plate. A flow field plate formed by the method is also provided.

    摘要： A method of coating a surface of a fuel cell plate is disclosed herein, and involves forming a sol gel mixture by mixing a weak acid and a composition including at least two metal oxide precursors. One of the metal oxide precursors is configured to be hydrolyzed by the weak acid to form a mixed metal oxide framework with an other of the metal oxide precursors having at least one organic functional group that is not hydrolyzed by the weak acid. The mixture is applied to the surface, and is condensed by exposure to air at least one predetermined temperature and for a predetermined time. The sol gel mixture is immersed in water at a predetermined temperature and for a predetermined time to form a porous, hydrophilic, and conductive film on the surface.
