SiEnergy Systems is a Harvard University spin-off commercializing novel ultra-thin film low temperature solid oxide fuel cells (SOFCs). The technology uses inexpensive high throughput fabrication methods to create SOFCs with ultra-thin film electrolytes that operate at the commercially desirable fuel cell operating temperature (350-550°C), and are scalable to meet various power requirements. Thin films reduce materials cost that will bring affordable SOFC technology into a commercially viable stage of development for broad market applications. In this presentation, recent advancement in thin film SOFC research and development at SiEnergy will be reviewed with particular emphasis on thin film electrode development, and cell size scaling. Progress towards further power output scaling by stacking multiple cells will also be discussed.
