Motivation for the Project
mobile application
stationary application
micro-SOFC
Sulzer Hexis, CH, 2000

• Scientific interests
• miniaturization and MEMS processing of SOFC
  materials and its periphery
• fundamental aspects of nanocrystalline thin films
• investigation of electrode kinetics, reforming
  and combustion processes

• Technical interests
• miniaturization of SOFC systems
• alternative to and improvement of
  state-of-the-art batteries
• very high energy density
• immediate charging
• long battery life-time
• geographical independence

Goal of the One-Bat Project

• Development of miniaturized SOFC hybrid power
  source for small electronic equipment
• Evaluation of micro-fabrication techniques for
  SOFC materials
• System operation directly on liquid gas (e.g.
  butane)
• Integration of significant achievements in fuel
  cell integration, gas processing, and heat
  management at the micro-system scale

Are micro-SOFCs feasible ? How could a micro-SOFC
look like?
