Abstract: Development of cost-effective, high-performance and non-precious electrocatalyst for Polymer Electrolyte Membrane Fuel Cell (PEMFC) is an essential requirement to replace Pt-group metal catalyst. Nanostructured transition metal carbides have attracted vast interest in fuel cell and electrolyser as electrocatalyst or support, due to its high conductivity and thermo-chemical stability. This paper provides a review in the recent experimental and theoretical studies on Titanium Carbides (TiC) as electro-catalyst and support for fuel cell and electrolyser. The morphologies of TiC show strong impact on the performance of the electrocatalyst in different oxidation and reduction reactions. This study discusses the electrochemical properties and synthesis processes for the development of different TiC nanostructure. The critical issues, challenges and the future perspective for TiC as electrocatalyst as well as electrocatalyst support in fuel cell and electrolyzer with desired activity and stability are also discussed.
