Project Description

Cummins Inc. will lead a team to develop and demonstrate a cost-effective, robust, and high efficiency scalable 5kW SOFC fuel cell power system that utilizes a novel lower-temperature (~600°C) Ceria electrolyte and metal-supported cell architecture. This project leverages Ceres Power’s novel and highly differentiated technology based upon the use of thick-film ceramics deposited on a ferritic stainless steel substrate, using doped ceria as the predominant oxygen‐ion conducting ceramic within the cell. Ceres’ technology has been demonstrated to perform high levels of internal methane reforming, with a path to complete internal reforming through further development. The scope of this project includes advancing the internal reforming capability of the cell, including improving robustness to anode and cathode contaminants through testing to understand poisoning mechanisms and rates and implementation of system mitigations. The scope also includes scaling up the cell active area from the current 1 kW format to enable an integrated stack module with power output of 5kW, which is in turn scalable to higher power levels through replication of the 5kW modular stack platform.

Project Benefits

The project will result in a lower cost, longer life SOFC system capable of greater on-off cycling and emergency shutdowns compared to conventional state-of-the art systems based on anode- and electrolyte-supported technology. The Ceres’s technology utilizes a novel lower-temperature (~600°C) Ceria electrolyte and metal-supported cell architecture. This unique SOFC architecture offers greatly enhanced robustness under real-world operating conditions at a lower cost than conventional SOFC designs, while retaining the advantages of fuel flexibility, high efficiency, reduced emissions, and low degradation.
