Year: 2026
Type: article
Abstract: ABSTRACT This study explores a 10‐kW hybrid energy system combining a medium‐temperature solid oxide fuel cell (SOFC) with a turbocharger, using ammonia as a hydrogen carrier. The principal innovation lies in the comparative analysis of unified integrated system with two configurations through diverse operating conditions, power range, application, and simulation tools against previous literatures, aimed at optimizing overall performance while maintaining exhaust temperatures below . Effective thermal management via heat exchangers and regulated air supply for optimizing SOFC cooling and power output, while precise combustion control supports nitrogen oxide () emission reduction. TRNSYS simulations validate the system's effectiveness, showing notable gains in fuel utilization, electrical efficiency, and reliability. Furthermore, the study applied optimization under two scenarios to compare equipment configurations. One scenario prioritized cost‐effective efficiency with fixed power outputs, while the other assessed performance based on tailored components. The initial configuration (1) consistently proves superior in power efficiency and SOFC utilization. These insights aid in developing efficient, sustainable SOFC‐GT hybrid energy systems.
