<P>PROBLEM TO BE SOLVED: To provide an electrode substrate for solid polymer fuel cell which solves conventional problems and is low cost, and by which supply and discharge of water and gas used in a reaction are performed smoothly, and cell performance is well demonstrated. <P>SOLUTION: There is provided a porous electrode substrate in which carbon staple fibers having a fiber diameter of 3-9 μm dispersed in a random direction on substantially two-dimensional plane are bound by a resin carbide of an indeterminate form, and the carbon staple fibers are bridged by the resin carbide with a minimum fiber diameter of 3 μm or less and of mesh shape. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
