Abstract

The present invention relates to a catalyst layer and a fuel cell comprising same. A catalyst layer according to an embodiment of the present invention comprises: a plurality of catalyst supports which are an electrically conductive material, provided in a column form having a predetermined length, and arranged to be spaced apart at a predetermined interval from each other; an ion-conduction channel which is an ion-conductive material and provided inside the catalyst supports; a catalyst provided in the form of particles having a predetermined size on the outer surfaces of the catalyst supports; and an ionomer provided on the outer surfaces of the catalyst supports.
