ACTIVATION METHOD OF MEA USING CYCLO VOLTAMMETRY

摘要

An activation method of MEA(membrane-electrode assembly) using cyclo voltammetry is provided to accelerate activation of MEA, to reach maximum performance within fast time, and to improve performance of the membrane electrode assembly. An activation method of MEA(membrane-electrode assembly) using cyclo voltammetry comprises the steps of supplying humidified gas for hydration of a membrane and an electrode; and performing cyclo voltammetry activation method for an electrode layer activation. The first step does not use an electron load and application device and supplies only humidified air. The second step circulates voltage with an arbitrary value at voltage of 0~3 V in cyclo voltammetry cycle.
