The effects of H2 and O2 gases on the typical fuel cell catalyst of Pt clusters on carbon particles (Pt on C) were examined using a special side-entry sample holder for high-resolution transmission electron microscopy. The holder can be used to transfer the specimen without exposure to air. The effects of H2 and O2 were detected after the specimen was exposed to the gases at 60 °C for 15 h. The predominant effect of H2 was the coagulation of the Pt clusters. The effect of O2 was to alter the structure of the carbon particles by oxidation.
