SOLID OXIDE CELLS
It Started with SOFC
Nexceris has a deep heritage in Solid Oxide Fuel Cell (SOFC) development and has established itself as a world leader in the field. We have considerable experience in producing SOFC cell manufacturing, stack design & modeling and fabrication & testing of SOFC stacks. Because we are vertically integrated, we are able to tailor our SOFC stack technology to meet application-specific requirements.
Starting in the mid 1990s, Nexceris was focused on the development of SOFC components and materials.
Nexceris’ Fuel Cell Business Unit has been active in the development of Solid Oxide Cell stack technology since 2006. The heart of the stack technology is based on our patented electrolyte-supported cell “FlexCell” design. These cell designs feature a thin electrolyte membrane layer that enables high performance and a dense cell periphery that provides an optimum sealing surface. Because the electrolyte provides the support, the electrode chemistry can be tailored to support a variety of applications. Our planar stack platform was designed and developed to be configured for high power density; where weight is critical to the end user. It can also be configured for systems where efficiency and lifetime drive the requirements. Because of this design flexibility, Nexceris’ stack using the FlexCell can support and array of applications such as: power generation, long-term energy storage, and reversible operation for grid support.
Core Areas of Focus
Currently, Nexceris is focused on solid oxide fuel cell applications related to Power Generation, Reversible for Grid Support and Long-Term Energy Storage.
REVERSIBLE FOR GRID SUPPORT
LONG-TERM ENERGY STORAGE
Nexceris has been developing materials, cells and stacks to support this application for over 25 years. Our stack is configurable for a variety of application needs such as: high power density and sulfur tolerant for logistic fueled applications (military or automotive) – or – high efficiency with the ability to internally reform light hydrocarbons for stationary applications (distributed power).
Long-term Energy Storage
Nexceris’ technology is capable of co-electrolysis providing a pathway to an array of value-added products, including hydrogen, ammonia, methane, methanol, carbon monoxide and other heavier fuels. Our solutions provide long-term energy storage through converting power to chemicals and can be highly efficient when coupled with processes that have waste heat and steam.
Reversible Operation for Grid Support
The final macro application of Nexceris stack technology is for reversible operation. This type of operation requires the stack to run both in Fuel Cell and Electrolysis modes. For this application the stack is operated in electrolysis mode to generate and store hydrogen when there is excess power from renewable energy sources on the grid, and switched to fuel cell mode to provide power when there is a deficiency.
