| Abstract |
| Solid oxide fuel cells (SOFC) have received wide interest due to the associated advantages of environment friendly
alternate energy source. Owing to the capability of efficient power generation from a broad spectrum of practical
fuels, viz. hydrogen, bio fuels, etc, SOFC finds potential applications in portable, mobile and stationary markets.
Presence of multi components, viz. anode, cathode, electrolyte, etc in single cell demands the maintenance of
mutual compatibility in SOFC. The present review describes the research work related to the development of anode
component. In addition, the present context also highlights the research work at CSIR-CGCRI, Kolkata, India,
focussed towards the development of planar anode-supported SOFC. Under this on-going activity, novel electroless
technique is employed to prepare nickel (Ni)-8 mol% yttria stabilized zirconia (YSZ) anode. Optimized processing
parameters of electroless technique impinge certain interesting features in the cermet, by the virtue of which major
shortcomings of conventional Ni-YSZ anode can be eliminated. Single cell with varied anode configurations have
been fabricated in which the electroless cermet acts as either anode-support, functional layer or as an
electrochemically active counterpart in multilayer anode system. A detailed discussion on the electroless anode is
presented in terms of its preparation and properties.
