The present invention is a driving step of operating by supplying fuel to a non-humidified fuel cell stack; A monitoring step of measuring a real-time voltage of the fuel cell stack; And a difference value between the set voltage and the real-time voltage measured in the monitoring step is calculated, and if the difference value is greater than 0, purging is performed, and then the operation step is performed again, and the difference value is less than 0 or 0. It relates to a method for automatically controlling optimal performance of a humidified fuel cell comprising a; controlling step of re-performing the monitoring step and changing a purging period according to the number of re-performing the monitoring step. Through this, the present invention provides an automatic control method for optimal performance of a non-humidified fuel cell and a control system using the same, while monitoring an operating state in real time, automatically controlling a purging cycle and a purging time to optimize the performance of the stack, and Implement the effect of reducing. |
