摘要
The electromotive force (emf) has been investigated for the hydride-hydride electrochemical cell under the influence of gradient magnetic fields. The thermodynamic consideration presumed the relationships between the emf and the gradient between the electrodes. The emf was measured for the array of the electrodes using the ferromagnetic metal hydride LaCo5Hx in the magnetic fields with the maximum gradient of 106 T/m up to 15 T at 293 K. The emf was proportional to the averaged gradient of magnetic fields and the distance between two electrodes and depended on the magnetic properties of the electrode material, which agreed well with the thermodynamic consideration.
