## Abstract

Provided is a packaged hydrogen-generating agent, the hydrogen-generating reaction of which is highly stable and repeatable, and which preferably is resistant to influence from changes in the environmental temperature. Also provided are a method for manufacturing said package, and a hydrogen generation method. The packaged hydrogen-generating agent is provided with: a hydrogen-generating agent (1); a covering material (2) which encloses the hydrogen-generating agent (1) and allows deformation; and a water-absorbing body (3), part of which is in contact with the hydrogen-generating agent (1). The covering material (2) preferably covers at least the area around the contact part (3a) where the water-absorbing body (3) and the hydrogen-generating agent (1) are in contact, so as to create a firm attachment at the contact part (3a).

## Claims

### Claim 1

A hydrogen-generating agent, comprising an epoxy resin and granular calcium hydride contained in a matrix of the epoxy resin, wherein the epoxy resin is a resin other than any water-soluble resin, the content of the granular calcium hydride being 60% or more by weight.

### Claim 2 (depends on 1)

The hydrogen-generating agent according to claim 1, wherein porosity (%) is 5% or less.

### Claim 3

A method for manufacturing a hydrogen-generating agent, comprising the step of hardening a mixture wherein granular calcium hydride is contained in an unset epoxy resin at a concentration of 60% or more by weight, wherein the epoxy resin is a resin other than any water-soluble resin.

### Claim 4 (depends on 3)

The method for manufacturing a hydrogen-generating agent according to claim 3, wherein the step of hardening is performed under pressure.
