Abstract

See full text

Provided is a fuel cell catalyst layer which has a catalytic performance equivalent to or higher than fuel cell catalyst layers containing platinum alone and which is inexpensive. The fuel cell catalyst layer of the present invention includes a metal oxycarbonitride-containing layer (I) and a platinum-containing layer (II). It is preferable that the mass ratio per unit area of the metal oxycarbonitride in the layer (I) to platinum in the layer (II) (metal oxycarbonitride/platinum) is 2 to 500. It is preferable that the mass per unit area of platinum in the layer (II) is 0.005 to 0.2 mg/cm2.
