Operation of CFCL's All-Ceramic Stack Technology

CFCL has entered into a commercialization phase that demands stacks perform to customer requirements. CFCL has designed, developed and is demonstrating its 4 th Generation solid oxide fuel cell stack technology to achieve the product requirements for stationary power applications, with the potential for volume fabrication and low cost. Stacks from 5 layer to 140 layer have been built and analyzed for structural and/or electrochemical performance characteristics. This paper demonstrates the robustness to thermal cycling from 28 layers to 140 layer stacks. A test procedure for large stack manufacture has been established and verified with two stacks fabricated for demonstration in technical demonstrator products. CFCL is continuing to develop and improve the Generation 4 stack design for improved efficiency, power outputs and long term stability.
