Abstract
A hybrid fuel cell system including a fuel cell for generating electric power by reacting fuel gas and oxidant gas, current restricting structure for restricting an output current of the fuel cell, a storage cell connected parallel to a series circuit comprising the fuel cell and the current restricting structure for helping the fuel cell to supply electric power to an external load, external load fluctuation detecting structure for detecting a fluctuation in the current demanded by the external load and current limitation adjusting structure for following the fluctuation in the current demanded by the external load by changing the restriction of the output current of the fuel cell which is made by the current restricting structure, with the passage of time.
