<p><P>PROBLEM TO BE SOLVED: To equalize a fuel supply volume and a fuel supply time to each part of electromotive parts of a fuel cell by improving a structure of curved parts of flow channels interrupting flow of liquid fuel. <P>SOLUTION: The fuel cell is provided with an electromotive part equipped with a membrane electrode assembly and a fuel storing part for storing liquid fuel. The fuel is supplied to a fuel electrode of the membrane electrode assembly from a fuel supplying part having a fuel injecting port connected with the fuel storing part and a plurality of fuel exhausting ports connected with the fuel injecting port through a fuel flow channel structured of straight line parts and curved parts. The curved parts 27 of the fuel flow channel are composed of a zone 29 in a clothoid line including at least a part connected with the straight line part 25. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
