Opportunities for Fabrication of SOFC Anode Using Selective Laser Melting

Abstract

Solid oxide fuel cells (SOFC) are electrochemical devices that have the potential to be the future for energy applications. However, current fabrication techniques could not fully optimize the performance of the anode. This paper looks into the opportunities of using additive manufacturing as a possible manufacturing technique for SOFC anode. In particular, selective laser melting (SLM) which is able to produce well-structured metallic products is discussed as a possible technique to fabricate functionally gradient anodes. Although SLM is a possible fabrication method, the limitation of minimum pore sizes produced still needs to be further researched. The study on SLM for SOFC is still at its early stages, and still needs more detailed studies to achieve the desired results.
