Pressure-composition isotherms in hydrogen storage alloy are generally measured by changing step by step the hydrogen pressure operating to the sample materials to obtain equilibrium pressure-composition relation in each pressure. Since this process requires long time and is tedious in manual operation,we have used mass flow controllers to inject or release hydrogen gas in a constant flow rate and have got such a characteristic curve automatically. In this report we show the hydrogen storage characteristics for a composite sample of LaNi5 alloy and carbon material in addition to pure LaNi5 alloy by using the designed and constructed apparatus. We confirmed that hydrogen storage characteristics in LaNi5 alloy in the composite sample are not influenced by the mixed carbon material.
