INTRODUCTION
Fuel cells have been extensively studied during these last
decades as they appear as environmentally friendly power
sources. They convert the chemicals hydrogen and oxygen into
water and electricity, via a reaction between fuel (on the
anode side) and an oxidant (on the cathode side) in the
presence of an electrolyte. The reactants flow into the cell, and
the reaction products flow out of it, while the electrolyte
remains within it. Fuel cells can operate virtually continuously
as long as the necessary flows are maintained.
Platinum is typically used as a catalyst to facilitate the chemical
reaction in polymer exchange membrane fuel cells (PEMFC). It
consists of a dispersion of nanoparticles.
