<P>PROBLEM TO BE SOLVED: To provide a power generation element for a liquid fuel cell in which supply of a fuel or oxygen to the deep part of the catalyst layer, and discharge of carbon dioxide and water from the deep part of the catalyst layer can be maintained smoothly even if the thickness of the catalyst layer is made thicker. <P>SOLUTION: This is the power generating element for the liquid fuel cell which is provided with a positive electrode 2 to reduce oxygen, a negative electrode 1 to oxidize the fuel, and a solid electrolyte film 3 arranged between the positive electrode 2 and the negative electrode 1. The negative electrode 1 and the positive electrode 2 include catalyst layers 1b, 2b of the thickness of 30 μm or more, in which the catalyst layers 1b, 2b contain a catalyst, a fibrous material, and a proton conductive material, and in which the length of the fibrous material is not less than 0.1 times the thickness of the catalyst layers 1b, 2b, and the liquid fuel cell is constituted by using that power generating element for the liquid fuel cell. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
