Investigation of Pt-supported nanographene produced by in-liquid plasma for development of
polymer electrolyte fuel cells

ecently, various fuel cells, such as polymer electrolyte fuel cell (PEFC), are attracting a lot of attention owing to small
size and at relatively low working temperature (below 80°C), which makes possible usage of PEFCs in automobile
and household power generation. However, PEFC has a problem with decrease of output caused by corrosion of
amorphous carbon used as a catalytic carrier, which could be solved by use of carbon nanostructures with stronger crystal
structure than amorphous carbon. In this work, nano-graphene supported by Pt nanoparticles was synthesized and
examined for possible application in development of PEFC with increased durability. Nano-graphene was synthesized
by in-liquid plasma generated in ethanol using AC high voltage (~11.7 kV). Amorphous component of synthesized
nano-graphene was removed by hydrogen peroxide treatment and removal of amorphous carbon was confirmed by
Raman spectroscopy. Platinum (Pt) nanoparticles were prepared on the surface of nano-graphene by the reduction of
Pt salt precursors (H2Cl6Pt) in solution. Formation of Pt nanoparticles of diameter in range 2-4 nm was confirmed
by transmission electron microscopy and X-ray diffraction measurement of Pt-supported nano-graphenes. Membrane
electrode assembly (MEA) was constructed, where Pt-supported nano-graphene was used as the catalytic layer. Power
generation characteristic of MEA were evaluated and current density for developed MEA was approximately 240 mA /
cm2. From the electrochemical evaluation of Pt-supported nano-graphene, it was found that durability of Pt-supported
nano-graphene was about seven times higher than that of carbon black, which looks promising for improvement of
durability of PEFC.
