HYDROGEN PRODUCTION DEVICE HYDROGEN PRODUCTION METHOD SILICON FINE PARTICLES FOR HYDROGEN PRODUCTION AND PRODUCTION METHOD FOR SILICON FINE PARTICLES FOR HYDROGEN PRODUCTION

摘要

A hydrogen production device (100) according to the present invention comprises: a pulverizing unit (10) for forming silicon fine particles (2) by pulverizing silicon chips or silicon grinding debris (1); and a hydrogen generation unit (70) for generating hydrogen by bringing the silicon fine particles (2) into contact with water or an aqueous solution and/or dispersing the silicon fine particles (2) in the water or the aqueous solution. Using this hydrogen production device (100) it is possible to produce with high reliability hydrogen in an amount that can sustain practical use using silicon chips or silicon grinding debris that are normally considered a waste product as the starting material. Therefore by effectively using silicon chips or silicon grinding debris the present invention contributes to protecting the environment and contributes to greatly reducing the cost of producing hydrogen to be utilized as a next generation energy source.
