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.
