Outline
At present, hydrogen fuel cell vehicles are gradually being commercialized in various countries, but the problems of high cost and poor lifetime of hydrogen fuel cells are still unsolved. In this paper, investigation is focusing on the performance requirements, research progress, simulation and key companies of Membrane Electrode Assembly (MEA) materials from materials and structures. Investigation results show that ultra-thin enhanced proton exchange membranes (PEM), low platinum loading catalysts and highly oxygen-permeable ionomers effectively improve the performance of MEA and are applied on current practice. At the same time, based on the summary of the current progress of hydrogen fuel cell membrane electrode development research, the shortcomings and development trends of the current membrane electrode researches are presented, and new ideas for the membrane electrode technology development and industrialization are proposed.
