  3. 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 General Introduction

  4. Emergence of Micro-Fuel Cells predicted performance state-of-the-art products (Source: Manhattan Scientifics & L. Livermore National Laboratories) General Introduction

  5. 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? General Introduction
