Abstract: PURPOSE: A catalyst layer for a fuel cell is provided to increase porosity and surface area, and efficiency because catalyst particles are evenly dispersed. CONSTITUTION: A catalyst layer(132) for fuel cell comprises nanofiber, pores which are dispersed in nanofiber, and catalyst particles adsorbed in pores. A method for manufacturing a catalyst layer for a fuel cell comprises the steps of: providing a spinning solution mixed with a base material, dispersed material and catalyst particles; electrospinning the spinning solution to form a nanofiber in which the dispersed material is dispersed in the base material and the catalyst particles are dispersed at the interface of the dispersed material and base material; and removing the dispersed material to form pores in which the catalyst particle is adsorbed in nanofiber.
