Abstract

There is provided a fuel cell system comprising a controller configured to control an opening position of a valve element of a flow dividing valve. The valve element is configured to be movable between a first position and a second position, according to the number of steps of a stepping motor that is provided to drive the valve element. When causing a fuel cell to perform power generation, the controller moves the valve element by a first number of steps such as to move from the first position to the second position and to additionally move the valve element toward the second position, based on a second number of steps that are taken from a time when the valve element starts moving from the first position toward the second position to a time when a voltage measured by a voltage sensor exceeds a predetermined value. This configuration provides a just enough number of steps to correct the position of the valve element and move the valve element to a position where the valve element is pressed against a valve seat.
