The cross effect between an ion flux and an electronic current in a nonstoichiometric binary oxide, $A_{1-\delta}O_\mu$, has been analyzed in the light of irreversible thermodynamics. It has been shown that a net flux of the mobile cation vacancy is induced through the system in an electrical potential gradient applied across a pair of the reversible electrodes, which makes the Fick frame shift relative to the laboratory frame. As a consequence, the relative shift is a measure of the effective charge responsible for the cross effect. Two experiments are proposed to measure the shift.
