Performance of Tubular Direct Carbon Fuel Cell Based on an Anode Support Solid Oxide Fuel Cell

A tubular direct carbon fuel cell based on an anode support solid oxide fuel cell was fabricated and studied. Carbon black and molten carbonate were filled in the inner part of the tubular DCFC cell. The performance of the tubular DCFC cell at 800 oC had a maximum power density of 97 mW/cm2; this result indicates that the fabricated tubular DCFC is a promising candidate for many other practical applications, such as residential power generation (RPG) and auxiliary power unit (APU) systems.
