<P>PROBLEM TO BE SOLVED: To provide a small direct methanol fuel cell suitable for a mobile phone or the like, capable of stably, continuously supplying direct liquid fuel from a fuel storage tank to each unit cell. <P>SOLUTION: The fuel cell A is formed in such a way that an electrolyte layer is installed on the outer surface part of a fuel electrode body and an air electrode layer is installed on the outer surface part of the electrolyte layer to form a unit cell, a plurality of unit cells are connected, a fuel supply body 30 having penetration structure to be connected to a fuel storage tank 10 storing liquid fuel or a fuel electrode body is connected to each unit cell to supply the liquid fuel, and the end of the fuel supply body 30 is connected to a spent fuel storage tank 40. A porous body having a capillary action and/or a relay core 40a comprising fiber bundles are/is arranged in the spent fuel storage tank 40, the spent fuel is exhausted to the spent fuel storage tank 40 through the relay core 40a, and part other than an exhaust hole 40b through the relay core is sealed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
