A fuel cell contains two or more fluid-supplying internal manifolds and fluid-discharging internal manifolds for each fluid. External manifolds include fluid-supplying external manifolds, which connect to the fluid-supplying internal manifolds, and fluid-discharging external manifolds, which connect to the fluid-discharging internal manifolds, for each fluid. The respective fluid-supplying and fluid-discharging external manifolds are positioned approximately in parallel with each other, extending in the width direction of a cell laminate body. |
