dc.description.abstractIn-Situ Resource Utilization (ISRU) allows consumption of local resources to produce life support consumables or propellants and is extremely critical for missions beyond low earth orbit where re-supply options are impractical. It is thus advantageous to develop unitized energy conversion device, capable of both energy storage and production within an integrated and process-intensified ISRU. Precision Combustion, Inc. (PCI), with support from NASA, continues to develop unitized, regenerative solid oxide stack system, capable of reforming lunar or Martian off-gases of various hydrocarbon lengths from methane to longer chain hydrocarbons for energy production (similar to battery discharging) as well as efficient H2O/CO2 electrolysis for energy storage (similar to battery charging). Challenges and risks regarding carbon deposition and thermal management associated with reversible hydrogen electrode for internal reforming have been addressed. The dual use regenerative fuel cell design is crucial to overcoming some of the known shortcomings of more traditional approaches. This approach has the potential to provide high power density, improve reliability, and enable quick cycling between power generation and electrolysis. In this paper, we will present results from performance evaluation of the unitized, regenerative solid oxide stack; including direct internal reforming and co-electrolysis of H2O and CO2. Results from durability and performance mapping at various operating conditions will be presented.en_US
