“…Fuel cells are electrochemical devices that convert the chemical energy directly into electrical power. It consists of an anode, cathode electrodes and a protonconducting membrane (electrolyte) sandwiched in between the electrodes [3][4][5]. These cells are characterized with high efficiencies, flexibility in size, quiet operation and lower emissions [3].…”

“…There are few reported studies that attempt to investigate separately the exergetic and economic performance of hydrogen fuelled low temperature PEMFC for transportation applications [5,18]. The exergetic performances of other PEMFC fuel cells for various applications have been studied using exergy method of analysis [19][20][21][22][23].…”

In this paper, a parametric study of a combined proton exchange membrane (PEM) fuel cell and triple‐effect absorption cooling system (TEACS) is undertaken to investigate the effect of different operating conditions and system parameters on the COPs, efficiency of the fuel cell and the integrated system's overall utilisation factor. It is found that the fuel cell efficiency increases from 40% to 44.5% as the operating temperature of the fuel cell increases. However, as the fuel cell's temperature and current density increase, the COPs decrease from 2.4 to 0.9 as a result of the increase in the energy output of the fuel cell ranging from 7.4 to 10.7 kW. The efficiency of the fuel cell decreases from 41% to 32% with an increase in both fuel cell's current density and membrane thickness. The overall utilisation factor of the integrated system decreases from 84% to 35% with an increase in the current density and molar flow rate. Finally, this study reveals that the present integrated PEM fuel cell unit with a TEACS can be considered as an attractive and environmentally benign option for cogeneration purposes in sustainable buildings.

While trying to optimize sharp distillation processes, the number of possible column sequences significantly increases as the number of components that make up the feed mixture increases. As a result, proper sequencing with maximum exergetic profit and minimum exergy destruction becomes harder to achieve. In this study, an exergoeconomic multi-objective optimization was applied to the distillation sequences of three separate hydrocarbon mixture cases, by means of a genetic-algorithm-based solver software. A computer program (DISMO) was developed in-house to achieve this functionality. The results indicate that the created algorithm was quite applicable in determining the optimum sequencing in distillation, as it successfully created the Pareto Solution Set and suggested the optimum configurations. This study also presented an opportunity to conduct a parametric investigation on various weighting factors for objective functions. As the importance given to a specific objective was increased, the optimization results had a tendency to favour that specific objective through arrangement of sequencing as expected, though the profit and sequencing converged to a single result after a certain threshold.
