CARBON FOAM
To provide a carbon foam that is unlikely to fall into a flow path or break during cell assembly.SOLUTION: The carbon foam of the present invention includes linear portions and connecting portions that connect the linear portions, and the linear portions have an average fiber diameter of 0.1 to 5.0 μm, and a Taber flexural rigidity measured in accordance with JIS P8125 of 10 gf cm or more. Further, in at least a part of the carbon foam of the present invention, when defining an average value of an orientation angle of the linear portions with respect to a x-direction as θavex, an average value of an orientation angle with respect to a y-direction as θavey, and an average value of an orientation angle with respect to a z-direction as θavez, difference θc between a maximum value and a minimum value in each of the θavex, the θavey and the θavez is preferably 3° or more.SELECTED DRAWING: Figure 5
【課題】本発明の目的は、セル組の際、流路への落ち込みや破断が起こりにくい炭素フォームを提供することにある。【解決手段】本発明の炭素フォームは、線状部と該線状部を結合する結合部とを有し、前記線状部の平均繊維径が０．１〜５．０μｍであり、ＪＩＳ Ｐ８１２５に準拠して測定されるテーバー曲げ剛さが、１０ｇｆ・ｃｍ以上であることを特徴とする。また、本発明の炭素フォームは、少なくとも一部において、前記線状部のｘ方向に対する配向角度の平均値をθａｖｅｘ、ｙ方向に対する配向角度の平均値をθａｖｅｙ、ｚ方向に対する配向角度の平均値をθａｖｅｚ、と定義したときに、前記θａｖｅｘ、前記θａｖｅｙ、前記θａｖｅｚの中の最大値と最小値との差θｃが３°以上であることが好ましい。【選択図】図５
