Abstract

A humidity sensing device for measuring a humidity of a reactant stream in a fuel cell system is provided. The humidity sensing device includes a humidity sensor coupled to a sensor housing. The sensor housing is adapted to selectively move the humidity sensor to an operating position and to a non-operating position in the fuel cell system. A fuel cell system and a method employing the humidity sensing device in the fuel cell system is also provided.
