The present invention is to provide a power generation unit successful in equalizing flow rates of fluids flowing through individual flow paths of a power generation cell, and is to provide a fuel cell which can flexibly be adapted to required power generation capacity, geometry. The power generation unit of the present invention comprises a power generation cell which is composed of a joint component of a pair of electrodes and an electrolyte component held between the electrodes, and a flow path forming component having a flow path allowing a fluid supplied to the joint component to flow therethrough; and a fluid conveyance apparatus having an opening commonly functioning as an intake port and a discharge port of the fluid. This enables equalizing of the flow rates of the fluid flowing in the flow path, resulting in equalization of flow rates of the fluids flowing through the individual flow paths.
