Abstract
Description
本願は、2012年11月16日出願の米国特許出願第13/694,299の優先権を主張する。その内容は参照によりここに組み入れられる。
E等価(MH対HgO/Hg)=−0.9324−0.0291logPH2ボルト (1)
等価気相プラトー圧力が表5に記載され、0.032〜1.126MPaの範囲にわたる。電気化学的システムにおける第1の5合金のプラトー圧力は、PCT装置において用いられた最高圧力(1.1MPa)よりも低い。したがって、電気化学的環境によって水素吸蔵プラトー圧力が減少し、ひいては吸蔵容量が増大する。無秩序MH合金のほとんどが、PCT等温線のaからbへの遷移において、はっきりしたプラトーを欠くという事実ゆえに、等価気相平衡水素圧力を見積もる第2の方法が考慮された。ネルンストの式の代わりに、2つのシリーズの非化学量論的なAB2合金及びAB5合金から得られたデータに基づくPCT脱着等温線の中点圧力とOCVとの実験的関係(図7)が確立された。図7は、2つのシリーズの先行技術の非化学量論的MH合金(AB2及びAB5)から30℃において測定された開回路電圧とPCT脱着等温線の中点圧力との関係をプロットする。当該曲線の良好な線形フィッティング(R2=0.96)を以下のように表現することができる。
log(中点圧力)=17.55OCV−23.87 (2)
式(2)を使用することにより、等価気相中点脱着圧力が、各サンプルのOCVから計算されて表5に記載される。得られた圧力はまた、PCT装置において用いられた最高圧力よりもかなり低い。したがって、双方の方法からの計算は一貫した結果を示す。すなわち、電気化学的環境においては、平衡水素圧力の減少ゆえに高吸蔵容量が得られた。
