NOVELTY - The method comprises contacting a fuel cell component with a titanium oxide-containing liquid to form a titanium oxide-containing layer adhered to the fuel cell component, and contacting the fuel cell component with a silicon oxide-containing liquid to form a silicon oxide coating adhered to the titanium oxide-containing layer. The steps of contacting the fuel cell component with the titanium oxide-containing liquid and the silicon oxide-containing liquid are repeated a predetermined number of times to produce/form the fuel cell component coated with multiple bilayers.    USE - The method is useful for coating a fuel cell component such as a bipolar plate with a bilayer (claimed), where the proton exchange membrane type fuel cell is useful as an electrical power source for automobiles.    ADVANTAGE - The method is capable of efficiently coating the fuel cell component with good hydrophilicity and increased chemical stability thus enhancing performance and electrical power of the thin, proton transmissive, non-electrically conductive and gas impermeable fuel cell.    DETAILED DESCRIPTION - The method comprises contacting a fuel cell component with a titanium oxide-containing liquid to form a titanium oxide-containing layer adhered to the fuel cell component, and contacting the fuel cell component with a silicon oxide-containing liquid to form a silicon oxide coating adhered to the titanium oxide-containing layer. The steps of contacting the fuel cell component with the titanium oxide-containing liquid and the silicon oxide-containing liquid are repeated a predetermined number of times to produce/form the fuel cell component coated with multiple bilayers. The titanium oxide-containing liquid includes titanium oxide nanoparticles. The titanium oxide nanoparticles have a size of 2-10 nm. The silicon oxide has a negative charge and the titanium oxide-containing layer has positive charge. The step of contacting the fuel cell component with the titanium oxide-containing liquid is performed by immersing the fuel cell component in a first bath containing the titanium oxide-containing liquid followed by withdrawal of the fuel cell component from the first bath. The step of contacting the fuel cell component with the silicon oxide-containing liquid is performed by immersing the fuel cell component in a second bath containing the silicon oxide-containing liquid followed by withdrawal of the fuel cell component from the second bath. The bilayer has a contact angle of less than about 3-20 degrees . The titanium oxide-containing layer and silicon oxide-containing layer have a thickness of 2-100 nm.
