This paper describes the low temperature operation of a solid oxide fuel cell using cubic stabilized zirconia in the ZrO2-Sc203-Al203 system as an electrolyte. The hydrogen-oxygen fuel cell was fabricated by using La08Sro 2MnO3 as the cathode material and Ni-YSZ as the anode material. The maximum power density is 0.63 W/cm 2 at 800~ and 1.0 W/cm 2 at 880~ The current-voltage performance of this fuel cell suggests that the present electrolyte is a good candidate for fuel cells operating in the temperature range between 800 and 900~ ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

Weak localization, fluctuation conductivity, and related problems have been investigated based on a comprehensive set of experiments on transition metal Nb films and wires. The temperature 0 dependence of the inelastic scattering rate 1/~& of films with various thicknesses (25-80 A), estimated from magnetoresistance data above T"is well fitted to a function of Co+C& T+C3T'. The coe%cient C& is in excellent quantitative agreement with the theoretical prediction of the electronelectron scattering mechanism for two-dimensional dirty metals. The coe5cient C3 shows no thickness dependence and is in semiquantitative agreement with theories of three-dimensional electronphonon scattering mechanisms. The upper critical field of thin Nb wires with a width of less than a 1000 A exhibits unconventional temperature dependence close to T, . We also discuss this behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
