Solid oxide fuel cells (SOFC) have much promise as efficient devices for the direct
conversion of the energy stored in chemical fuels into electricity. The development of highly
robust SOFC that can operate on a range of fuels, however, requires improvements in the
electrodes, especially the anode, where nanoscale engineering of the structure is required
in order to maximize the number of sites where the electrochemical reactions take place. In
this article we review the approaches that are currently being used to improve anode …
