A novel cathode supported honeycomb SOFC for intermediate temperature operation has been developed for application as a compact power module with quick start-up and shut-down functions. In this study, effects of resistances of glass sealant and anode current collector formed on the edge face of the honeycomb on the SOFC performance was investigated using an electrical simulation and a practical electrochemical evaluation method. Open circuit voltage (OCV) for a honeycomb SOFC unit was improved with an increase in the resistance glass sealant or a decrease in anode current collector. The fabricated honeycomb SOFC showed the OCV values above 1.05 V in a temperature range of 500 to 600 °C.
