The Characteristics of Hybrid Al2O3:SiO2 Nanofluids in Cooling Plate of PEMFC

A Proton Electrolyte Membrane fuel cells (PEMFC) is considered to be a viable alternatives Internal Combustion Engines (ICEs) in automotive applications due the key advantages thermal management system. The main duty of system maintain desirable temperature, with uniform temperature distribution across stack and.its.individual membranes. In this paper, enhancement PEMFC cooling plate was analysed and presented. hybrid Al₂O₃:SiO₂ used as coolant distributor plate. study focuses on water based 0.5% volume concentration single Al₂O₃ , SiO₂ nanofluids, Al₂O₃:SiO nanofluids mixture ratio 10:90, 20:80, 50:50, 60:40 90:10. effect different ratios heat transfer fluid flow Reynold number range 400 2000 observed. 3D computational dynamic (CFD) developed plates using Ansys 16.0. Positive obtained where 10:90 has highest coefficient compared other used. However, all experienced higher pressure drop. Therefore, advantage analyze both enhancements drop demerits for adoption. results concluded that nanofluid most feasible candidate up Re1000. positive implied do improve behaviour better potential future management.
