Abstract
The electrochemical properties of a novel honeycomb solid oxide fuel cell (SOFC), supported by an extruded cathode monolith and capable of generating high-volumetric power density under intermediate temperature operation, are reported. The SOFC was fabricated via the extrusion of a cathode honeycomb support and channel surface coating with electrolyte/anode bilayers using a wet chemical process. Under humidified H2 fuel flow, high-volumetric power density above 2 and 3 W cm−3 at 0.7 V was exhibited at 700 and 750 °C, respectively. In addition, microstructure observation and electrochemical analyses confirmed that the honeycomb SOFC has structural durability for the rapid start-up operation with a heating rate of 100 °C min−1.
