PURPOSE:To improve electrolyte holding quality, mechanical strength, etc., by using a beta type silicon carbonide whisker, in which a diameter and aspect ratio are specified, for a base material. CONSTITUTION:An electrolytic matrix for a fuel cell is molded to a thin plate shape of equal quality porous composition by blending about 2-20% resin system securing agent of polytetra fluoroethylene or the like in a beta type silicon carbonide whisker 0.1-0.5mum in diameter and 100 or more in aspect ratio. This matrix, in which the silicon carbonide whisker of high purity monocrystal is applied to a base material, is inverted into a strong thin plate molded material having fine equal quality porous composition through a molding process. In consequence, excellent wet and holding quality for an electrolyte and high mechanical strength are provided. |
