Abstract

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.
