Abstract: The present disclosure provides a method for manufacturing a catalyst layer and the method includes the following steps. First, a solution fabrication step is provided for fabricating a solution. The solution includes a solvent, a polymer and a titanium-containing precursor. A layering step is then provided for evaporating the solvent to form a gel-like layer, and a nitridation step is performed for treating the gel-like layer in ammonia ambience to remove the polymer so as to obtain a catalyst support, in which the catalyst support is composed of titanium nitride with a plurality of pores. A catalyst preparation step is performed for forming a plurality of platinum particles on the catalyst support.
