Abstract:	Due to their high specific energy and high energy density, miniaturized low-temperature (350-550°C) solid oxide fuel cells, hereafter abbreviated “micro-SOFC”, are believed to constitute one of the technologies that could help satisfy the continuously increasing electric energy demand for mobile devices such as laptops and camcorders. Using thin film and MEMS technologies, cathode-electrolyte-anode layer assemblies as thin as 1 μm are deposited on silicon substrates that are micromachined to form arrays of free-standing membranes (surface area: 390x390 μm2 at ETH Zurich). Proof of concept was already established by several groups and high power densities of several hundreds of mW/cm2 have been reported at temperatures as low as 350 °C. In Switzerland, the OneBat® consortium consisting of eight research groups is working on the development of the micro-SOFC technology covering various aspects such as membrane fabrication and characterization, reformer catalysis, thermal management and system development. After a brief presentation of the consortium activities as well as the state-of-the-art of the micro-SOFC research worldwide, this contribution will lay emphasis on the core of the micro-SOFC technology, namely the electrochemical cells, and address key-aspects for their further development: fabrication and thermomechanical stability of free-standing membranes, development of cost-effective thin film deposition techniques, and development of thermally stable electrodes.
