• The studies of effects of high magnetic fields on the equilibrium for metal (intermetallic compound)-hydrogen systems have been reviewed. The equilibrium hydrogen pressures for the systems of LaCo_5-H, GdCo_5-H and Y_2Co_7-H were measured in magnetic fields up to 15T with a water-cooled magnet (WM-5) and up to 26T with a hybrid magnet (HM-1). The application of magnetic fields causes the hydrogen pressure to increase in LaCo_5H_4 (50% increase in 26T), whereas it cause the pressure to decrease in GdCo_5H_<2.53> (1.7% decrease in 14T) and the single β phase of Y_2Co_7H_x (15% decrease in 14T). These observed changes in the hydrogen pressure agree well qualitatively and quantitatively with the value derived from a thermodynamic theory and magnetic data. It is first found that the potential of the electrochemical system was shifted 1.0mV by a magnetic field of 10T for the LaCo_5-H cell.
