Abstract: In this paper microwave-assisted synthesis of a special catalyst, namely, Pt/C catalyst comprised of nanoparticles is discussed. Owing to its unique characteristics, the catalyst is very beneficial to the performance of proton exchange membrane fuel cells (PEMFCs). As mentioned in the article, Pt nanoparticles once integrated with Carbon, provide better catalytic activity/stability. Such integration has been achieved successfully by microwave heating. The relevant experimental works of some researchers are briefly reviewed in the end.
