<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of matrix materials as well as a matrix type cathode structure and its manufacturing method in order that deterioration of mechanical strength of the matrix type cathode structure is suppressed and a prescribed porosity is formed stably. <P>SOLUTION: (a) Primary particles consisting of spherical or amorphous metal grains and metal particles of smaller grain size than that of the primary particles are mixed together with a binder, (b) the mixture of mixed material is dried and solidified, (c) the solidified mixture is pulverized to form a powdered material in which two or more of the primary particles and the metal particles of smaller grain size are joined together, and (d) by sieving the powdered material which has at least a larger size than that of the primary particles, secondary particles are formed in which joint parts of the primary particles are covered by the metal grains of smaller grain size. This matrix material is furthermore sintered and adhered onto the surface of the cathode base body in order to manufacture the cathode structure. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
