NOVELTY - The method involves preparing (200) catalyst ink of predetermined viscosity. An electrode substrate including pair of surfaces is masked (210) with magnetic mask. A catalyst ink is sprayed (220) on first treatment area and catalyst ink is dried (230) by heating electrode substrate and magnetic mask in an oven at predetermined temperature for predetermined period of time. The catalyst ink is sprayed (240) on second treatment area and catalyst ink is dried (250) by heating electrode substrate and magnetic mask in oven at predetermined temperature for predetermined period of time.    USE - Method for fabricating membrane electrode assembly for fuel cell.    ADVANTAGE - The viscosity of the catalyst ink is sprayed with the pressure, speed and nozzle size of the spray device so as to achieve the appropriate loading and uniformity of the homogenized catalyst ink. Thus the fabricating time for membrane electrode assembly can be reduced, the amount of overspray can be reduced and the catalyst can be reduced. The fabrication of a low loading catalyst coated electrode substrate reduces the material cost by reducing the amount of precious metal in the catalyst, and simplifies the fuel cell manufacturing process by eliminating hot-pressing while maintaining fuel cell performance without appreciable potential loss.
