Abstract |
PEM fuel cell is making a promising candidate as the next generation power sources for vehicle and other mobile applications of all sizes down to mobile phones, because of its compactness. The world-wide commercialization of PEM fuel cells has not yet gotten accomplished. The greatest barriers are durability and expense. Considering durability, fuel cell components receive degradation during long-period operations.
To overcome the barriers and maintain high fuel-cell efficiency, catalyst layer must be identified and developed. There are various ways for changing the catalyst characteristics. Although in most instances there is no significant interaction between the metal and the substrate, strong bonding can be proved in a recently discovered class of supported-metal catalysts. This, in turn, cause many changes in the catalytic and chemisorption characteristics and the morphology of the metal particles. However, the property was not well known when the same amount of metal was loaded on various supporting materials. Because there are few examples researched in detail, we have synthesized monodisperse palladium nanoparticles dispersed on various supporting materials, and to prove change of catalytic characteristics by supporting material, we compared them by electrochemically measuring them with formic acid.
