PROBLEM TO BE SOLVED: To provide a fuel cell having stable cell output, wherein a reaction distribution among stacked unit cells is uniform, and droplets are rapidly discharged from a passage groove even in a low-pressure operation at low current density. SOLUTION: This fuel cell is provided with a fuel cell stack composed by stacking a plurality of unit cells each formed by sandwiching a membrane-electrode assembly 1 from both its sides by a fuel separator plate 3 equipped with a fuel passage groove 22 and an oxidizer separator plate 2 equipped with an oxidizer passage groove 23. A fuel communication manifold penetrating in the stacking direction is formed on the membrane-electrode assemblies 1, the fuel separator plates 3 and the oxidizer separator plates 2. The fuel passage grooves are made to communicate with one another in intermediate parts thereof by the fuel communication manifold. The fuel communication manifold is divided into a plurality of independent spaces in the fuel cell stack. COPYRIGHT: (C)2008,JPO&INPIT
