A polymer electrolyte membrane fuel cell that includes a positive electrode, a negative electrode, a polyelectrolyte membrane and a solution of reduced graphene oxide and/or graphene oxide functionalized with metallized nanoparticles. The electrodes are coated with a polymer and the polyelectrolyte membrane has a hydrophobic exterior surface that is subjected to ultraviolet/ozone (UV/O) exposure, which changes the hydrophobic, exterior surface to a hydrophilic exterior surface. The polyelectrolyte membrane is disposed between the positive electrode and the negative electrode and can include a sulfonated tetrafluoroethylene based fluoropolymer-copolymer. The solution forms a coating on the hydrophilic exterior surface of the polymer electrolyte membrane and the positive and negative electrodes. The positive and negative electrodes can be coated with a polymer, preferably polytetrafluoroethylene (PTFE) that can be subjected to ultraviolet/ozone (UV/O) exposure. The metallized nanoparticles increase the efficiency of the fuel cell by at least 50% when the feed gas includes at least 1000 ppm carbon monoxide.
