摘要

能源消耗的大幅增加，引起了人们对清洁能源生产的关注。太阳能是一种无限量的能源。利用太阳能，非常适合太阳强度高的地方。方法对采用两台喷射器和两台蒸发器的CO2循环系统进行了研究。建立了LS-2抛物槽集热器模型，利用Cu-water纳米流体将收集的太阳能转移到主循环。采用质子交换膜（PEM）燃料电池对纳米流体进行预热，为泵提供动力。采用进化多目标遗传算法对系统运行条件进行优化。利用MATLAB软件进行优化。结果表明，该涡轮可产生9.247 kW的输出功率。汽轮机发电功率的比火用成本为97.050美元/GJ。PTC、PEM燃料电池和涡轮的火用损失分别为45.104 kW、21.831 kW和0.999 kW，这是由于摩擦损失和热力学过程的不可逆性造成的。PTC的火用破坏占总火用破坏的61%。在不同地点对该系统进行的评价表明，利雅得和巴格达对拟议的系统具有很大的潜力。系统优化结果表明，汽轮机最大可获得功为13.199 kW，汽轮机功率成本率为4.114美元/h。根据不使用化石燃料的建议配置，该系统可以为离网地区提供可持续和清洁的电力生产。同时，作为燃料电池产品的水是一种对环境无害的清洁产品。研究发现，高潜力的太阳能城市支持研究配置的可持续性。

Exergy and exergoeconomic evaluation and optimal design of a solar-powered system integrated with PEM fuel cell and TEG for cleaner production

Background

Considerable increase in the energy consumption, raised concerns over clean energy production. The solar limitless energy is one of the renewable sources. Utilizing the solar energy, is perfectly suitable for location with high solar intensity.

Methods

In this research, a combined cooling and power (CCP) CO₂ cycle, which is employing two ejectors and two evaporators is studied. LS-2 parabolic trough collector was modeled and Cu-water nanofluid was used to transfer the collected solar energy to the main cycle. Proton exchange membrane (PEM) fuel cell is employed to preheat the nanofluid and supply pumps power. The system operating conditions were optimized using evolutionary multi-objective genetic algorithm. The MATLAB software was used to perform the optimization procedure.

Significant Findings

Results indicate that the turbine can generate a power output of 9.247 kW. The specific exergy cost of turbine produced power was 97.050 $/GJ. The exergy destruction for PTC, PEM fuel cell, and turbine were 45.104 kW, 21.831 kW, and 0.999 kW, respectively which are caused by friction losses and irreversibilities of thermodynamic process. The exergy destruction of PTC was 61% of total exergy destruction. The evaluation of the system in different locations revealed that Riyadh and Baghdad have great potential for the proposed system. Additionally, the optimization results for proposed system revealed that the maximum obtainable work of turbine was 13.199 kW with a turbine power cost rate of 4.114 $/h. According to the proposed configuration which operates without the use of fossil fuels, this system could provide sustainable and clean power production for off-grid areas. Also, water as the product of the fuel cell is a clean product which is not harmful for environment. The findings for studied city which are high potential solar places supports the sustainability of the studied configuration.
