METHOD AND APPARATUS FOR CONTROLLING OPERATION OF DIRECT METHANOL FUEL CELL SYSTEM

摘要

PURPOSE: A driving method of direct methanol type fuel cell system is provided to recover the performance of the catalyst contaminated by by-product like carbon monoxide through simple method, thereby maintaining the output electricity stably. CONSTITUTION: A driving method of direct methanol type fuel cell system comprises a step of operating a fuel cell system in the state the connection of load and the supply of air and fuel are discontinued for specific time. The direct methanol fuel cell system comprises a stack(100), a mixing tank(110) collecting and storing unreacted fuel and air, a fuel tank(120) supplying fuel to the mixing tank, and a fuel pump(121) supplying mixed fuel to the stack, and a control part(130) operating the system for specific time, and operating the system in the state the connection of load and the supply of air and fuel are discontinued for specific time.
