The positive electrode active material layer is placed on a surface of the positive electrode substrate. The positive electrode active material layer includes a first layer and a second layer. The first layer is interposed between the positive electrode substrate and the second layer. The positive electrode active material layer includes a positive electrode active material, carbon black, and fibrous carbon. A mass fraction of the carbon black in the first layer is higher than a mass fraction of the carbon black in the second layer. A mass fraction of the fibrous carbon in the second layer is higher than a mass fraction of the fibrous carbon in the first layer.

Improved polymer-based materials are described, for example for use as an electrode binder in a fuel cell. A fuel cell according to an example of the present invention comprises a first electrode including a catalyst and an electrode binder, a second electrode, and an electrolyte located between the first electrode and the second electrode. The electrolyte may be a proton-exchange membrane (PEM). The electrode binder includes one or more polymers, such as a polyphosphazene.
