NOVELTY - Method for high-efficient in-situ activation of a membrane electrode of a proton exchange membrane fuel cell, involves performing in-situ activation to assemble the membrane electrode into a single cell, detect its air tightness, then introduce in hydrogen and air and cycle the output voltage of the cell to achieve the purpose of in-situ activation of the membrane electrode of the proton exchange membrane fuel cell. USE - Method of high-efficient in-situ activating proton exchange membrane fuel cell membrane electrode used in fuel cell device for converting chemical energy into electric energy. ADVANTAGE - The method enables to activate proton exchange membrane fuel cell membrane electrode in-situ with high efficiency, which optimizes the three-phase interface of the membrane electrode, improves the diffusion and transmission of the water, gas and electron, shortens the activation time of membrane electrode by the voltage circulation and adding carbon and pore-forming agent material.
