Book excerpt: Catalytic processing of fuels was explored in this thesis for both low-temperature polymer electrolyte membrane (PEM) fuel cell as well as high-temperature solid oxide fuel cell (SOFC) applications. Novel catalysts were developed to generate hydrogen for PEM applications from the oxidative steam reforming of methanol. The activity of lanthanum nickel perovskite (LaNiO3) was examined in both dilute fuel and full fuel conditions. Autothermal operation was successfully achieved with higher hydrogen selectivity than conventional Pd-based catalysts. The selected complex oxide catalyst was applied as a thin film onto a 0.2 [mu]m-thick Pd membrane. Pure hydrogen effluent was obtained from the resulting microreactor as desired for PEM applications. SOFC systems would be of interest for portable power generation if the thermal cycling and slow start-up issues could be addressed. One potential solution is the development of Si-supported ultrathin electrolyte structures (~100 nm-thick) of low thermal mass. Due to the low maximum fabrication temperature (
