| Outline of Final Research Achievements |
In this study, spherical silica powders introduced as a pore control layer to a porous SUS support with average pore diameter; 0.5 micrometer; having wide pore distribution. The thickness of palladium membrane electro-less plated was 10.9 micrometer and the membrane showed high hydrogen permeance and the durability.
For having thinner palladium membrane, the particle size and the amount of introduced silica particles were optimized for porous SUS support with average pore diameter; 0.2 micrometer. The thickness of membrane reduced to 1/3 times, the hydrogen permeance increased three times and high hydrogen diffusion was achieved. As the result, the optimized introduction method of spherical silica powders to porous SUS supports was established as the preparation technic of thin palladium membrane.

| Academic Significance and Societal Importance of the Research Achievements |
水素社会の実現にはいくつかの方策がある。我々が注目する「オンサイト水素製造」では、パラジウム（Pd）膜をベースとした膜型水素製造器の開発が進められている。しかし、Pdの価格は昨今高騰しており、高い水素透過性を得るためにも薄膜化が求められる。そこで、本研究でこの薄膜化を実現するために確立した「支持体細孔をセラミックス系微粒子で制御する技術」は微粒子工学の観点からも意義深い。さらに、「制御された支持体表面へのPdの薄膜化技術」は社会実装可能な技術の提案という点から社会的意義が大きい。
