Thermal Analysis On Heat Transfer Enhancement And Fluid Flow for Low Concentration of Al2O3 Water - Ethylene Glycol Mixture Nanofluid in A Single PEMFC Cooling Plate

Numerical analysis of thermal enhancement for a single Proton Exchange Membrane Fuel Cell (PEMFC) cooling plate is presented in this paper. A low concentration of Al2O3 in Water - Ethylene Glycol mixtures was used as coolant in 220mm x 300mm cooling plate with 22 parallel mini channels of 1 x 5 x...

A low concentration of Al2O3 in Water - Ethylene Glycol mixtures was used as coolant in 220mm x 300mm cooling plate with 22 parallel mini channels of 1 x 5 x 100mm.
