16. Proton conductivity of lanthanum and barium zirconate: Microscale aspects on first-principles basis
Sammanfattning : Fuel cells are devices which convert chemical energy into electrical energy cleanly and efficiently. Development of fuel cells compatible with hydrocarbon fuels would make more efficient use of present fossil and renewable fuels, and also enable progress towards a future hydrogen economy. LÄS MER
17. Yttria-Stabilized Zirconia and Gadolinia-Doped Ceria Thin Films for Fuel Cell Applications
Sammanfattning : Solid oxide fuel cells convert chemical energy directly into electrical energy with high efficiency and low emission of pollutants. However, before fuel cell technology can gain a significant share of the electrical power market, the operation temperature needs to be reduced in order to decrease costs and improve the durability of the cells.

18. Physical Vapor Deposition of Yttria-Stabilized Zirconia and Gadolinia-Doped Ceria Thin Films for Fuel Cell Applications
Sammanfattning : In this thesis, reactive sputter deposition of yttria-stabilized zirconia (YSZ) and cerium gadolinium oxide (CGO) thin films for solid oxide fuel cell (SOFC) applications have been studied. All films have been deposited under industrial conditions.YSZ films were deposited on silicon wafers as well as commercial NiO-YSZ fuel cell anodes. LÄS MER
19. Carbon nanomaterial-based interconnects, integrated capacitors and supercapacitors
Sammanfattning : The constant miniaturization and steady performance improvement of electronics devices have generated innovative ideas such as internet of thing (IoT), which also includes devices with integrated energy sources. The high performance is conceived by the high density of the devices on a chip leading to a high density of interconnects, to connect these devices to outside world. LÄS MER
