Abstract: A negative electrode for an electrochemical cell of a secondary lithium metal battery is manufactured by a method in which a precursor solution is applied to a major surface of a lithium metal substrate to form a protective interfacial layer thereon. The precursor solution includes a first organic solvent mixture, a dioxolane, and a fluorinated organosilane. The protective interfacial layer exhibits a composite structure including a polymeric matrix component and a lithium-containing dispersed component embedded in the polymeric matrix component.

Abstract: A valve for a hydrogen fuel cell module, a hydrogen fuel cell module including a valve, and a method of applying a surface coating on a valve. The valve includes a valve body defining an interior including a base material. The base material has a first surface. The valve also includes a surface coating disposed on the base material. The surface coating includes a surface layer having a second surface opposing the first surface. The surface layer contacts the first surface, and the surface layer comprises a first polymer. The surface coating also includes a dielectric layer contacting the second surface. In a hydrogen fuel cell module, the valve is connected to an exhaust flow path downstream of at least one of an anode or a cathode of a hydrogen fuel cell stack.
