Description
次に、以上製造した各種Pd合金箔を水素透過膜として水素透過性を評価した。この評価試験では、水素透過膜をステンレス製のホルダーで固定し、これを反応管に漏れが生じないように設置し、水素透過膜の両側(1次側及び2次側)をロータリーポンプにより排気して1.0×10−1Pa以下の真空にした後、試験温度(150℃、200℃、300℃、400℃、450℃、500℃、550℃)に加熱・所定時間保持した。その後、水素ガス(純度99.99%)を1次側に2.5MPa導入し、1次側の圧力P1、及び2次側の圧力P2を測定した。そして、測定された圧力の単位時間変化から水素透過束J、水素透過係数φを算出し、これにより各水素透過膜の水素透過性を評価した。
