PURPOSE: A pressure-composition isotherm measuring system of a hydrogen absorbing alloy is provided to accurately measure the absorption or desorption diagram of hydrogen by automatically implementing experiments based on a controlling part. CONSTITUTION: A pressure-composition isotherm measuring system of a hydrogen absorbing alloy includes a hydrogen injecting part(112), a measuring container(114), a first valve(115), a reacting part(116), a second valve(117), a pressure sensor part(118), a hydrogen discharging part(119), a third valve(120), and a controlling part. The measuring container is in connection with a hydrogen injecting part and stores hydrogen. The first valve opens and closes a part between the hydrogen injecting part and the measuring container. The second valve opens and closes a part between the measuring container and the reacting part. The pressure sensor measures the pressure of the measuring container and pressures between the measuring container and the reacting part. The third opens and closes the discharging part. Hydrogen is injected into the measuring container based on a pre-set pressure. Valves are closed, and a second valve is opened to measure pressures between the measuring container and the reacting part. The absorbing rate of the hydrogen according to the changing of pressure with respect to a specimen inserted into the reacting part is calculated by the controlling part. |
