Abstract
A hydrogen discharger comprising hydrogen discharge pipes for discharging hydrogen from hydrogen-containing gas contained therein, which are made from palladium and constituted to be satisfactory in terms of discharge efficiency, heating and sealing and an apparatus comprising the hydrogen discharger such as an absorption type refrigerating apparatus. A plurality of hydrogen discharge pipes of a hydrogen discharger are provided and a heater is installed therebetween to improve heating efficiency. An open end portion having a conical inner surface of the hydrogen discharge pipe and a nozzle portion having a conical outer surface with a plurality of stepped portions of an introduction pipe are connected to each other by pressure to ensure sealing. The hydrogen discharge pipe is made from an alloy comprising 20 to 30% of silver and the balance consisting of palladium so that the hydrogen discharge pipe is suitable for various hydrogen discharge applications. Particularly, an alloy containing 23% of silver and the balance consisting of palladium makes it possible to provide a hydrogen discharge pipe which is excellent in hydrogen discharge characteristics and heating characteristics.
