ABSTRACT
Energy efficiency is a global need to decrease net emissions and optimise the use of renewable energy sources. Ongoing research focuses on optimizing the use of renewable energy resources to maximize their consumption. Fuel cells, which utilise water to generate electricity, are among these renewable energy resources. Nevertheless, as previously said, there is ongoing research focused on optimising the synthesis of hydrogen and the extraction of voltage and current. In this study, we present the utilisation of sodium hydroxide (NaOH) in the extraction of hydrogen and silica nanoparticles for the enhancement of power values. The experiment clearly demonstrates that using a 50% NaOH solution resulted in the production of about 5.602 litres of hydrogen gas. Furthermore, the molar percentage of hydrogen in the final product was determined to be 85.74%. The gas chromatography analysis findings indicate that the product contains 81.58% hydrogen, 11.62% nitrogen, and 0.04% carbon dioxide. The electrical efficiency achieved is 86% with a heat loss of 13.96%. In addition, the research included the introduction of silica nanoparticles into the water. It was noted that this led to an increase in power density when the relative humidity was about 70%. The study also revealed that these nanoparticles had the potential to boost fuel cell performance.
