Description

technical field [0001] The invention relates to the technical field of hydrogen isotope storage and supply, in particular to a ZrCo-based hydrogen isotope storage alloy with high circulation capacity and its preparation and application. Background technique [0002] The exploitation and use of traditional fossil energy have caused energy crisis and environmental pollution, two difficult problems to solve. Therefore, the development of clean energy that is pollution-free, renewable and highly utilizable has become the main theme in the field of energy research. [0003] Deuterium-tritium nuclear fusion reaction can release huge energy, and it has the characteristics of clean, safe and efficient. In view of this, countries around the world have jointly built the International Thermonuclear Experimental Reactor (ITER) to further explore controllable nuclear fusion technology. During the operation of the reactor, the outside world needs to supply or recover hydrogen isotope gas...
