Hydrolytically-Stable Hydrophilic Coating for Bipolar Plates

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 o...

Zusammenfassung:	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.
