ELECTRODE FOR FUEL CELL COMPRISING INK LINES WITH DIFFERENT DIRECTIONS, METHOD OF PREPARING THE SAME, MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL COMPRISING THE SAME

摘要

PURPOSE: An electrode for fuel cell, a preparing method for the same, and a membrane electrode assembly employing the electrode are provided to improve the performance of the fuel cell. CONSTITUTION: An electrode for fuel cell comprises a catalyst layer(13) where a plurality of catalyst portions are laminated. The each catalyst portion comprises a plurality of ink lines or ink spot lines(11,12). Catalyst particles and ionomers dispersed in a solvent are sprayed to electrolyte membrane(201) or gas diffusion layer(208) to form ink lines or ink spot lines. The plural ink lines or ink spot lines are separated from each other.
