The EMFs of hydrogen isotope cells with H2-D2 gas mixtures against H2 and D2 reference gases were measured at 700 °C using CaZr0.90In0.10O3-α as a proton-conducting solid electrolyte. Steady electromotive forces (EMFs) with quick response were obtained. The EMFs were almost linear functions of the gas composition of the H2-D2 mixtures and were consistent with those theoretically estimated. Such defined EMFs can be used to monitor H2/D2 ratios in hydrogen isotope mixtures.
