Technology developed: Exfoliated Graphite for Bipolar Plates Applications (TP19768189325)
Category: Nil
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. N Rajalakshmi International Advanced Research Centre for Powder Metallurgy and New Materials Centre for Fuel Cell Technology Senior Scientist
Technical Application Area: Energy/Power
If 'Other', please specify:
Please give more details of new technical application area:
Exfoliated graphite represents the high volume modification of graphite obtained as the result of chemico thermal treatment of natural graphite flakes. Exfoliation of graphite is a process in which graphite expands irreversibly by up to 300 times resulting in a puffed up material with low density and high surface area. Exfoliated graphite which has high electrical conductivity and low density can be used in the production of bipolar plates for use in PEM fuel cell stack. These lightweight bipolar plates reduce the weight of ultimate fuel cell stack and helps in improving the fuel cell performance.

THE VISION
THE MISSION
ABOUT I-STEM
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.
