発明の名称 (英語) Hydrogen gas generating member and hydrogen gas producing method therefor
発明の概要(英語) (EP2213617)
There is provided a hydrogen gas generating member which safely facilitates the hydrogen gas generation reaction by bringing an Al alloy which is subjected to rolling treatment or powdering treatment into contact with water.
A hydrogen gas generating member 20 includes a texture in which Al is finely dispersed in a metal matrix, where hydrogen gas is generated by bringing the hydrogen gas generating member into contact with water.
A fixing member 14 for mounting the hydrogen gas generating member 20 is provided in a hydrogen generating apparatus 10 and is brought into contact with a water 15 that is stored inside.
The hydrogen gas generated from the surface is supplied outside through a hydrogen gas collecting pipe 12 and stored in a storage tank (not shown).
