Description
本願発明の課題は例えば、下記の構成を備えた触媒構造体および燃料電池により解決される。
(1):担体と、前記担体の上に形成されたナノドットと、前記ナノドットの上に形成された触媒粒子を備えた触媒構造において、前記担体を構成する材料の格子定数と前記ナノドットを構成する材料の格子定数の差を1%以上16%以下とすることである。
(2):担体と、前記担体に隣接して形成されたナノドットと、前記ナノドットの上に形成された触媒粒子と、前記触媒粒子に接触して形成されたコーティング材料を備えた触媒構造において、前記担体を構成する材料の格子定数と前記ナノドットを構成する材料の格子定数の差を1%以上16%以下とすることである。
本実施例の主な効果は、前述したように、担体1と触媒粒子2の格子定数の差が16%
以下である場合に、触媒粒子の拡散が抑制されて触媒粒子のサイズを室温において十分小さくすることができることである。そこで、触媒粒子2の担体1との界面近傍での拡散係数を計算し、その格子不整合依存性を解析することによってこの効果を示すことができる。分子動力学シミュレーションにより拡散係数を計算する方法は、例えばフィジカルレビューB(Physical Review B)の第29巻(1984年発行)の5367ページから5369ページまでに記述されている。
