Abstract
【解決手段】Ti,Zr,V,Ni、及び改質剤元素を含む多相金属水素化物の合金材料であって、AB2結晶構造を有する前記改質剤元素の濃度がゼロより大きい第1の主要相又は相群と、第1の相又は相群の改質剤元素濃度よりも少なくとも10倍高い改質剤元素濃度を有する第2の相とを含む。前記改質剤元素は、Niが主たる成分でありイットリウムをオプションとする軽希土類元素を含む。
【選択図】図1
Description
(SEM)が使用されて相分布及び組成が研究された。各サンプルの圧力・吸蔵量・温度(PCT)特性が、鈴木商館の多チャンネルPCTシステムを使用して測定された。PCT分析では、各サンプルが最初に、25気圧のH2圧力における300℃と室温との間の2時間熱サイクルによって活性化された。その後、30及び60℃のPCT等温線が測定された。材料はその後、例えば、その開示が参照としてここに組み入れられる非特許文献1及び2に開示された先行技術の技法に従って金属水素化物電池セルに組み入れられた。
