Method and apparatus for managing fuel cell performance and direct methanol type fuel cell using the method

摘要

The present embodiments relate to a method and an apparatus for managing fuel cell performance and a direct methanol type fuel cell using the method, capable of setting an activation time point to a user's use time point and spontaneously performing performance recovery during long time use thereof. The method for managing performance of the fuel cell stack according to the present embodiments includes the steps of: receiving a first drive request signal or a performance recovery request signal; circulating high-concentration liquid fuel having higher density than fuel supplied to a stack through an anode flow of the fuel cell stack in response to the received request signal; and circulating water through the anode flow after stopping the circulation of the high-concentration liquid fuel.
