<P>PROBLEM TO BE SOLVED: To provide a fuel cell that has high battery performance, can improve the gas-sealing performance of fuel gas and oxidizer gas with the edge structure of the unit cell of the fuel cell, and can suppress a decrease in OCV. <P>SOLUTION: In a tube type unit cell 1 for fuel cells, an inner collector 11, a first catalyst electrode layer 12, an electrolyte layer 13, a second catalyst electrode layer 14, and an outer collector 15 are laminated and arranged coaxially from an axial center successively. In the tube type cell 1 for fuel cells, at least in one edge of the unit cell 1, at least the electrolyte layer 13 projects from the second catalyst electrode layer 14 and the outer collector 15, and the outer-periphery surface of the projecting electrolyte layer 13 appears. <P>COPYRIGHT: (C)2008,JPO&INPIT |
