<P>PROBLEM TO BE SOLVED: To provide a fuel cell wherein a current density distribution is uniformized to stabilize a power generation current by spreading a supply gas throughout electrodes with uniform concentration, and a gas leakage prevention measure is facilitated by equalizing pressure in a gas passage. <P>SOLUTION: Each separator 4 for holding electrodes 3 is composed of a first separator 5 and a second separator 6; a part contacting the electrodes 3 is recessed on a surface contacting the electrode 3 of each first separator 5 to form a first gas storage space 7; a second gas storage space 8 having nearly the same shape as that of the first gas storage space 7 is formed on a joint surface between each first separator 5 and the corresponding second separator 6; and the first gas storage space 7 is made to communicate with the second gas storage space 7 through multiple communication holes 9, whereby the supply gas introduced into the second gas storage space 8 can be run into the first gas storage space 7 through the communication holes 9 and supplied to each electrode 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
