Abstract
Bipolar plate for Proton Exchange Membrane (PEM) fuel cell was fabricated with various
materials and characterized by different techniques. Two types of gas flow fields, serpentine &
parallel, were designed for bipolar plates and their effect on the functioning of fuel cells was
investigated. Pressure drop between the two designs, at inlet and outlet of gases was different
and its effect was reported. In the fabrication process of membrane electrode assemblies
(MEA), the platinum catalyst was synthesized in the laboratory and this catalyst was deposited
on the Nafion membrane with the help of ionomer emulsion. Then gas diffusion layers were
placed on both sides of the membrane. Different MEAs versions (imported and indigenous)
were assembled and tested in the fuel cells and their efficiency was evaluated in terms of
current, voltage and power. A fuel cell test stand was developed to operate and test the
working of single cell and fuel cell stack is also described. Polarization curves were drawn to
evaluate the performance of fuel cells. These studies are directed at the development of
different fuel cell components which are tested under the same conditions for comparison.
