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?
