A fuel cell is formed as a stack of a plurality of unit cells, each unit cell including an electrode unit held by separators, each electrode unit including a solid polymer electrolyte membrane held by a pair of electrodes. Fluid passages extend through the stack in a stacking direction of the stack. An insulating supply-discharge member having a fluid passage communicates with at least one of the fluid passages extending through the stack. A current collection member is held between the supply-discharge member and the stack. An isolating element is positioned to fluidically isolate the current collection member from a fluid in the fluid passage of the supply-discharge member and from the fluid passages extending through the stack. The fuel cell has high reliability and high generating efficiency, and can be produced at low cost.
