In this work, a novel integrated system based on a combination of solid oxide fuel cell (SOFC) with compressed air energy storage (CAES) and turbocharger is presented for simultaneous production of domestic hot water and power in the scale of retail buildings for peak shaving applications. The SOFC subsystem is the primary power generation unit, which is coupled with CAES and other supporting auxiliary cycles. The energy, exergy, and emissions are quantified through parametric analysis for evaluating the overall system performance. The preliminary results for the scenario analyzed indicate a power generation of 272 kW during 4 hours in off-peak period, as well as a power generation of 407 kW during 7 hours in peak demand periods. The round trip energy and exergy efficiencies for the integrated system are 78% and 58%, respectively. Also, the overall emissions of the proposed integrated system is reduced by 0.06 kgCO₂/kWh in comparison to the standalone SOFC system. The afterburner accounts for the main source of irreversibility and exergy destruction among all components. Overall, the integrated system is superior to the standalone SOFC system from energy, exergy and emissions perspectives.

在这项工作中，提出了一种基于固体氧化物燃料电池（SOFC）与压缩空气储能（CAES）和涡轮增压器相结合的新型集成系统，用于同时生产零售用水规模的高峰期剃须用的家用热水和电力应用程序。SOFC子系统是主要的发电单元，与CAES和其他支持辅助循环耦合。通过参数分析对能源，火用和排放进行量化，以评估整个系统的性能。所分析场景的初步结果表明，在非高峰时段的4小时内发电272千瓦，在高峰需求时段的7小时内发电407千瓦。集成系统的往返能源效率和火用效率分别为78％和58％。也，与独立的SOFC系统相比，为₂ / kWh。加力燃烧器是所有组件不可逆转和火用破坏的主要来源。总体而言，从能源，火用和排放的角度来看，集成系统优于独立的SOFC系统。
