A charger and discharger for a secondary battery includes a secondary battery coupled to an output stage of the charger and discharger, a first converter circuit including a first pulse voltage generator that outputs a first pulse voltage according to a first duty ratio, and a first inductor that outputs a first current in proportion to a value of an integral of the outputted first pulse voltage with respect to time to a positive electrode terminal of the secondary battery, a second converter circuit including a second pulse voltage generator that outputs a second pulse voltage according to a second duty ratio, and a second inductor that outputs a second current in proportion to a value of an integral of the outputted second pulse voltage with respect to time to a negative electrode terminal of the secondary battery, and first and second controllers controlling the duty ratios of the first and second pulse voltage generators, respectively.

Charger and discharger for secondary battery

A fuel cell system and a control method thereof are capable of preventing anode flooding due to a temperature difference between a stack and reformate upon starting a fuel cell system. The method of controlling a fuel cell system including steps of detecting a temperature of a fuel cell stack, detecting a temperature of reformate that is generated in a fuel reformer and then is supplied to the fuel cell stack through a heat exchanger, and setting the temperature of the reformate to be lower than the temperature of the fuel cell stack during a starting time of the fuel cell system.
