A hydride secondary battery includes: a pressure vessel; a positive electrode disposed in the pressure vessel; a negative electrode disposed in the pressure vessel; and hydrogen gas with which the pressure vessel is filled. The negative electrode contains a hydrogen-absorbing alloy. In a pressure-composition-temperature diagram, a desorption curve at 25&#xb0; C. of the hydrogen-absorbing alloy has a plateau pressure of 0.15 MPa or more and 10 MPa or less. The hydrogen gas has a pressure equal to or higher than the plateau pressure at 25&#xb0; C. of the hydrogen-absorbing alloy.

High pressure type hydride secondary battery

A method for producing a metal nanoparticle complex according to the present invention is a method for producing a metal nanoparticle complex in which metal nanoparticles are supported in pores of a porous body, said method comprising at least: an adsorption step of allowing an organic metal complex to adsorb in pores of a porous body; and a decomposition/reduction step of heating the porous body, which has had the organic metal complex adsorbed in the pores thereof, under a reductive atmosphere to decompose an organic compound in the organic metal complex adsorbed in the pores of the porous body and also reduce a metal cation in the organic metal complex, thereby causing metal nanoparticles to be supported in the pores of the porous body.
