Patent ID: 8389179

Claim:
A fuel cell comprising: a cell stack comprised of a plurality of cell units each having a cell stacked with a separator having an anode fluid path, the cell having an anode and a cathode connected together through an electrolyte membrane; and a manifold for supplying an anode fluid to a position of each cell unit facing the anode fluid path, the manifold comprising: a fluid supply plate having a flow conduit provided with an opening part for feeding an anode fluid; a top plate; a bottom plate having a plurality of openings formed in an upper surface of the bottom plate and arranged in a preselected direction so as to face the anode fluid path, the upper surface of the bottom plate forming with an inner surface of the top plate a flow space configured to receive an anode fluid fed from the opening part of the flow conduit, to reduce a flow rate of the received anode fluid, and to disperse the anode fluid at the reduced flow rate along a plane direction orthogonal to the preselected direction of arrangement of the plurality of openings; and a block group arranged on the upper surface of the bottom plate between the plurality of openings and the opening part of the flow conduit so that the flow space is disposed between the block group and the opening part of the flow conduit, the block group comprising a plurality of blocks spaced apart from one another to form a plurality of paths for dispersing into the plurality of openings the anode fluid dispersed by the flow space at the reduced rate.
