"solid solution of tantalum and titanium oxide is required and that the nanoparticles should be around five nanometers... 6-4 ratio of tantalum to titanium oxide is required... when the scavenger nanoparticle material was added to the reactions of fuel cell systems, hydrogen peroxide yield was suppressed to less than 2%—a 51% reduction... current density decay of fuel cells was reduced from 33% to only 3%"
