Article Description

Hybrid nanofluid is a new revolutionized cooling liquid with improved thermo-physical properties as compared to conventional coolant. This paper presents the feasibility of hybrid AlO–SiO nanofluids as an advanced coolant for PEM fuel cell application in terms of thermal–electrical–hydraulic thermo-physical properties. Nine mixture ratios of AlO–SiO were used in this experiment, ranging from 10:90 to 90:10 mixture ratios. The result demonstrated that both thermal conductivity and electrical conductivity decreased as the percentage of AlO was increased in the mixture. In contrast, the dynamic viscosity property increased as the AlO percentage ratio was increased. In summary, property enhancement ratio (PER) of thermo-hydraulic (PER) and thermo-electrical (PER) was established. Both PER and PER analyses favor 10:90 ratio of AlO–SiO hybrid as the most feasible ratio for the implementation in PEMFC. This is due to the dominant effect of thermal over viscosity and electrical conductivity.
