The effect of prepolymer crystallinity on the solid-state polymerization (SSP) of poly(bisphenol A carbonate) was examined using nitrogen as a sweep fluid. A low-molecular-weight prepolymer was synthesized by melt transesterification and prepolymers with different crystallinities (11.7%, 23.3%, 33.7
Fuel cells with BaZr 0.1 Ce 0.7 Y 0.2 O 3-d (BZCY) proton-conducting electrolyte is fabricated using spray-modified pressing method. In the present study the spray-modified pressing technology is developed to prepare thin electrolyte layers on porous Ni-BZCY anode supports. SEM data show the BZCY el
