Abstract: The development of Ti_2Ni-type oxygen-stabilized intermetallic phases as hydrogen storage alloys was reviewed in present paper. The stabilization of oxygen-stabilized intermetallic phases and their hydride, the relationship among component, structure and the hydrogen absorption properties of Ti_2Ni-type oxygen-stabilized intermetallic phases were summarized and discussed. The developing trend of oxygen-stabilized intermetallic compounds was also reviewed. Besides, our works were reported in the paper about the Zr_3V_3O_x intermetallic hydride.
