PURPOSE:To enable to convert heat of a heat source without passing a transient characteristic region, by connecting an orifice and a check valve in series to a hydrogen gas conduit which connects a container for hydrogenated metal and a hydrogen gas storing tank to each other, and further connecting an inverted check valve to the conduit in parallel to the orifice and the former check valve. CONSTITUTION:An orifice 12 and a check valve 14 are connected in series to a hydrogen gas conduit 4 which connects a hydrogenated metal retainer 2 and a hydrogen gas storing tank 3 to each other, and another check valve 13 is also connected to the conduit 4 in parallel to the orifice 12 and the check valve 14. Here, the check valve 14 allows hydrogen gas to flow only in a direction from the tank 3 to the retainer 2, while the check valve 13 allows hydrogen gas to flow only in the opposite direction. Heat of a heat source 6 is given to hydrogenated metal 1 by a heat exchanging means 9 and then transmitted to a heat medium fluid by a heat exchanging means 10. Remaining heat is used for separating hydrogen gas from the hydrogenated metal 1, and hydrogen gas thus produced is stored in the tank 3 via the check valve 13. In case that the quantity of heat produced by the heat source 6 is not sufficient, the amount of hydrogen gas in the container 2 is reduced. In this state, hydrogen gas is supplied from the tank 3 to the container 2 via the orifice 12, so that the temperature of the container 2 is kept at a required level by the heat produced when hydrogen gas supplied from the tank 3 is occluded by the hydrogenated metal 1. |
