A High Performance Low Temperature Direct Carbon Fuel Cell

A high performance direct carbon fuel cell is developed, where Ni-Gd0.1Ce0.9O2-x cermet, a molten carbonate composite, and Sm0.5Sr0.5CoO3 are used as anode, electrolyte, and cathode, respectively. The cell can be operated at relatively low temperatures with power densities of 188, 108 and 48 mWcm-2 being achieved at 600, 550, and 500oC, respectively, when graphite-carbonate and CO2-O2 mixture are used as fuel and oxidant.
