Abstract

EXTENSIVE RESEARCH AND DEVELOPMENT EFFORTS ARE BEING UNDER TAKEN IN RECENT YEAR IN THE FIELD OF PEM FUEL CELL (PEMFC) SYSTEMS TO MAKE THEM COMMERCIALLY VIABLE. IN PROTON EXCHANGE MEMBRANE FUEL CELLS, STABILITY AND DURABILITY ARE IMPORTANT OBJECTS FOR COMMERCIALIZATION. IT IS WELL-KNOWN THAT CATALYST DEGRADATION AND CARBON-SUPPORT CORROSION ARE THE MAIN FACTORS REDUCING STABILITY, AND USING PT NANOCATALYST ON CARBON NANOTUBE SUPPORTS INSTEAD OF PT/C INCREASE STABILITY AND DURABILITY AFTER LONG-TERM AGING. IN THIS WORK, A HYDROTHERMAL METHOD WAS EMPLOYED TO PREPARE PT NANOPARTICLES DISPERSED HIGHLY ON MULTIWALLED CARBON NANOTUBES WITH 19.4 WT. % PT. MEMBRANE ELECTRODE ASSEMBLES (MEAS) FROM TOW CATALYST FABRICATED WITH THIN FILM METHOD. IN FUEL CELL TEST STATION, THE POLARIZATION, AC IMPEDANCE AND CYCLIC VOLTAMMETRY EXPERIMENT OF MEAS AND ALSO ADT TEST WAS DONE. THE PT/C CATALYST SHOWED NO ACTIVITY IN FUEL CELL TESTING AFTER 2000 POTENTIAL CYCLES DUE TO SEVERE CARBON CORROSION, PT DISSOLUTION, AND CATALYST PARTICLE SINTERING. CONVERSELY, THE PT/MWCNT CATALYST SHOWED BETTER ELECTROCHEMICALLY ACTIVE SURFACE AREA AND ALSO DURABILITY AFTER A POTENTIAL CYCLING. THE ANALYSIS OF AC IMPEDANCE SPECTRA ASSOCIATED REVEALED THAT THE PRESENCE OF CNTS SIGNIFICANTLY REDUCED INCREASING OF ACTIVATION RESISTANCES. THE PERFORMANCE OF FRESH MEA FABRICATED FROM PT/C WAS BETTER THAN FRESH PT/MWCNT MEA, BUT AFTER ADT TEST HAD MORE REDUCE. LOSS ELECTROCHEMICAL ACTIVE SURFACE AREA OF PT/C CATALYST WAS HIGHER THAN PT/MWCNT CATALYST DUE TO MORE CATALYST PARTICLE SINTERING.
