METHOD FOR REVERSE ACTIVATION OF FUEL CELL

摘要

PURPOSE: A reverse activation method of a fuel cell is provided to induce the concentration of hydrogen and air to become uniform distribution along a longitudinal direction of a separator, and to improve the performance of an electrode membrane assembly. CONSTITUTION: A reverse activation method of a fuel cell comprises a first activation step and a second activation step of a fuel cell. The first activation step is progressed by supplying a fixed flux of hydrogen and air to a hydrogen inlet(12a) and air inlet(14a) of the fuel cell, and then discharging the reacted hydrogen and air through the hydrogen inlet and air inlet. The activation step is progressed as the first activation step by exchanging the hydrogen inlet and air inlet for a hydrogen outlet and air outlet, and the hydrogen outlet and air outlet for hydrogen inlet and air inlet.
