1. A fuel cell assembly at least one cell comprising an electrolyte layer (2), a pair of gas diffusion electrode layers (3, 4) interposing the electrolyte layer between them, and a pair of flow distribution plates (5) for defining passages (10, 11) for fuel and oxidizer gases that contact the gas diffusion electrode layers, characterized by that:

  • each flow distribution plate is provided with a central recess (51, 52) having a number of projections (53, 54) formed therein; and

    an electrode terminal layer (55, 56) is formed on each projection to establish an electric connection with an external circuit;

    each gas diffusion electrode layer defining the passages for fuel and oxidizer gases by covering the central recess, and provided with a porous layer (3a, 4a) formed over each flow distribution plate so as to cover the electrode terminal layer.
