Abstract:

A leaky hydrogen pump-gauge with an internal hydrogen reference was constructed by combining two ceramic disks based upon the proton conductor CaZn_0.9In_0.1O_3−a and inserting a spacer to provide an internal chamber between them. The spacer included an aperture so that the internal chamber was connected via the aperture to the external gas. With the addition of electrodes to the ceramic disks one disk acted as a hydrogen pump and the other as a Nernstian gauge. Hydrogen pressure within the internal chamber was influenced both by hydrogen leakage via the aperture and by electrochemical pumping. Application of a rectangular current to the pump enabled hydrogen pressure of surrounding gas to be successfully determined in a wide range by using a method of analysis to eliminate the leakage effect. This device is applicable to the measurement of a fluctuating hydrogen partial pressure.
