A power supply system includes a power storage module including first and second power storage units spaced by a predetermined distance from each other, and a power generating unit being capable of contacting with both of the first and second power storage units concurrently, and formed of a thermoelectric converting element; and a control unit for controlling charging and discharging of said first and second power storage units. In the first and second power storage units, different thermal reactions occur depending on whether charging or discharging operations is performed. The thermal reactions are a heat absorbing reaction and a heat generating reaction. The control unit renders one of the first and second power storage units dischargeable, and renders the other power storage unit chargeable.
