We proposed the totalized hydrogen energy utilization system that consists of a fuel cell device, a water electrolysis device and metal hydride tanks, and developed the mathematical model of hydrogen storage system that composes of several metal hydride tanks. The discharging hydrogen performance was investigated experimentally and numerically. As a results, it was shown that if the circulating water piping that flows in metal hydride tanks was connected with the series, and control method that increased the number of operating tanks are adopted when the outlet pressure of hydrogen decreases, hydrogen in each tank could be efficiently used.
