<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of attaining light weight. <P>SOLUTION: The fuel cell (10) is provided with a membrane electrode assembly (20) and current collectors (30, 40) which are arranged along the electrode face of the membrane electrode assembly or embedded in the electrode at least partially and have conductivity and gas permeation performance. The current collectors have a different cross-section according to the distribution of the output current amount of the membrane electrode assembly in surface direction of the membrane electrode assembly. In the fuel cell, the cross-section of the current collector can be made small according to the distribution of the output current amount of the membrane electrode assembly, thereby the light weight of the fuel cell can be attained. <P>COPYRIGHT: (C)2010,JPO&INPIT |
