Highly Efficient, Durable Regenerative Solid Oxide Stack

Precision Combustion, Inc. (PCI) proposes to develop and advance a highly efficient regenerative solid oxide stack design. Novel structural elements allow reforming of regolith off-gases (e.g., methane and high hydrocarbons) within a solid oxide stack as well as efficient H2O/CO2 electrolysis, overcoming shortcomings of traditional approaches. The resulting design offers the potential for light-weight and simple design with high efficiency and durability. This effort would be valuable to NASA as it would significantly reduce the known spacecraft technical risks and increase mission capability/durability/efficiency while at the same time increasing the TRL of regenerative solid oxide systems for ISRU application. The technology concept of our highly-efficient regenerative Solid Oxide Stack was demonstrated in Phase I and will be advanced in Phase II.
