## Fracture energy and crack growth in surface-treated YSZ for SOFCs The SOFC electrolyte, yttria-stabilized zirconia (YSZ), was coated and co-sintered with different electrode coatings. Two energy release rates -for crack initiation and arrest -characterized the cracking behavior. A 30-50% improve

Methanol electro-oxidation on Pt-modified Au nanoparticles was studied in aqueous 0.5 M H 2 SO 4 /1 M CH 3 OH. The Pt-modified Au nanoparticles showed lower values than pure Pt nanoparticles in area-specific current densities. The activity also decreased with lower amounts of Pt on the Pt-modified A
In this study, a low-cost and high performance catalyst with core-shell structure of PdCu@PtRu/C for methanol oxidation is prepared by a two-step replacement reaction. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) examinations show that the composite catalyst particles distribut
