A polyaromatic electrolyte for a fuel cell electrode includes a structure represented by Formula 1, wherein in Formula 1, Ar is a neutral unit represented by one of Formula 2A and Formula 2B: The fuel cell electrode may include a catalyst suspended in the polyaromatic electrolyte.

Polyaromatic electrolytes for alkaline membrane fuel cells

The present disclosure provides phosphonated polymers that can be used, for example, as polymer electrolyte membranes (PEMs) and/or catalyst ionomeric binders for electrodes in PEM fuel cells, and more particularly for high-temperature PEM fuel cells. High-temperature PEM fuel cells that use phosphonated polymers of the present disclosure suffer from reduced or no acid leaching because, in at least some examples, phosphonic acid moieties are covalently bound to the backbone of the polymers. A phosphonated polymer include a backbone having one or more aromatic monomers, with each aromatic monomer having one or more phosphonic acid groups. A phosphonic acid group may include phosphonic acid or a functional group that is hydrolysable into phosphonic acid.
