System Simulation and Analysis of an LNG-Fueled SOFC System Using Additively Manufactured High Temperature Heat Exchangers

A laboratory-scale solid oxide fuel cell (SOFC) system using liquefied natural gas (LNG) as a is designed to be used an energy converter on seagoing vessels (MultiSchIBZ project). The presented design phase supported by thermodynamic simulation. As heat integration plays crucial role with regard recirculation and endothermic pre-reforming, the exchanger pre-reforming component models need exhibit high degree of accuracy throughout entire operating range. Compact additively manufactured tube-bundle plate-fin exchangers are achieve exchange efficiencies at low pressure losses. Their transfer correlations derived from experimental tests under conditions. simulation study utilizing these characteristics carried out for four configuration variants integration. behaviour analyzed outlet temperature processing module. combination allothermal exhibits best performance nominal full load yields partial capability up 60% electrical net 58 (LHV).
