| description | To provide a fuel cell catalyst capable of exhibiting high activity under a low load and a high load.SOLUTION: A catalyst for a fuel cell includes a carbon carrier having pores and a catalyst metal supported on the carbon carrier. The carbon carrier is so configured that mode diameters of mesopores are between 2.5 nm or more and 5.0 nm or less, a BET specific surface area is 700 m/g or more and 1300 m/g or less, a median diameter of grain sizes is 0.10 μm or more and 0.50 μm or less, and crystallite sizes in a (002) plane of carbon is 5.0 nm or more and 12.0 nm or less.SELECTED DRAWING: Figure 1
【課題】低負荷時及び高負荷時において高活性を発揮することができる燃料電池用触媒を提供する。【解決手段】細孔を有するカーボン担体、及び前記カーボン担体に担持されている触媒金属を含む燃料電池用触媒であって、前記カーボン担体は、メソ孔のモード径が、２．５ｎｍ以上５．０ｎｍ以下であり、ＢＥＴ比表面積が、７００ｍ２／ｇ以上１３００ｍ２／ｇ以下であり、粒径のメディアン径が、０．１０μｍ以上０．５０μｍ以下であり、及び炭素の（００２）面における結晶子サイズが、５．０ｎｍ以上１２．０ｎｍ以下である、燃料電池用触媒。【選択図】図１ |
