Summary of SOFC research:
Induction plasma technology has been successfully developed to synthesize the SOFC materials as well as the components. The nano-structured electrodes have very unique microstructures: each large agglomerate consists of smaller ones, which in turn contains even smaller particles. The resulting porous structures have large pores for rapid gas transport and extremely large surface area for fast electrochemical reactions. SOFCs with these electrodes have shown very low interfacial polarization resistances at intermediate temperature. Suspension plasma spraying process could produce much denser electrolyte compared to solution plasma spraying process. Preliminary results obtained at the Université de Sherbrooke have demonstrated the feasibility of induction plasma spraying process applied to produce the porous nano-structured electrodes as well as dense electrolyte coatings. This represents an opportunity to fabricate the fully integrated nano-structured SOFC using solution and suspension plasma spraying process.
