Research Abstract

A research on the application of hydrogen concentration cell based on a new-type proton conductive solid electrolyte SrCe_<0.95>Yb_<0.05>O_3-delta to the analysis of hydrogen in molten aluminum was performed and the following results were obtained. The methods to determine the thermochemical properties such as electrical partial conductivities and transport numbers were established for this electrolyte. The manufacturing technique was achieved and equal quality of electrolytes became to be constantly obtained. The conduction mechanism was investigated by the measurements of the conductivities, the emf's and the polarizing currents of the concentration cells and the hydrogen solubility in the electrolyte. In the relative high oxygen potential regions, the mechanism was made clear sufficiently. The dependency of emf on the oxygen and hydrogen potentials at the electrodes were investigated in detail by using gas concentration cells. The concentration cell immersed into the molten aluminum in the hydrogen atmosphere gave reasonable emf's but those into the melt in the air atmosphere was found not to normally operate. They showed low emf value corresponding to the very high hydrogen potentials and the responses to the changes of atmosphere were not obvious. The more fundamental investigations on the conduction mechanism in very low oxygen potentials and the behaviors of oxide film formed on the interface between electrolyte and melt were found essential to develop the sensors for practical use.
