Description
Summary:	Solid Oxide fuel cell (SOFC) is one of the potential sources of alternative energy. Investigation has been carried out to improve the power density of the intermediate temperature SOFC by optimizing the composition of the anode materials. Nickel Oxide (NiO) and Gadolinium doped Ceria (GDC) have been used as anode materials. And graphite has been used as a pore former in the anode substrate. Samples have been characterized successfully at three different operating temperatures (600, 550 and 500° C). The maximum open circuit voltage (0.86V) and peak power density (48.62 mW/cm 2 ) have been obtained from the sample with composition of NiO, GDC and graphite in 25, 50 and 25 volume % respectively.
