Fuel cell

A fuel cell has cell units and a manifold for uniformly supplying an anode fluid to the cell units. The manifold has a fluid supply plate with a flow conduit for feeding an anode fluid, and a plate structure having a flow space and openings arranged in a preselected direction. The flow space receives an anode fluid fed from an opening part of the flow conduit, reduces a flow rate of the anode fluid, and disperses the anode fluid at the reduced flow rate along a plane direction orthogonal to the preselected direction. The block group is arranged between the openings and the opening part so that the flow space is disposed between the block group and the opening part. The block group comprises blocks spaced apart from one another to form paths for dispersing into the openings the anode fluid dispersed by the flow space at the reduced rate.
