The present disclosure relates to the methods to synthesize shape tailored ordered intermetallic nanomaterials, PdCu3 and its application as electrocatayst in the fuel cell. More particularly, the present disclosure relates to the synthesis of ordered PdCu3 nanomaterial starting from a spherical nanocrystal with (111) crystallographic exposed to a cubic nanocrystal with 100 plane exposed, and its excellent efficiency as both cathode and anode material, surpassing the activity and stability of the state-of-the-art Pt/C electrocatalyst. The present disclosusre further relates to the unique, cost-effective way of synthesizing ordered Pd based nanocrystal in different shapes with different exposed crystallographic planes for catalysis. The present disclosure also relates to fuel cell device fabrication and applications of said nanomaterial as bi-functional electrode material (active both as anode and cathode).

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
