Abstract

A combined heating and power system (CHP) based on solid oxide fuel cells (SOFCs) is established to meet the electrical and heating demand of a 1645 m² building. Given the high cost of SOFC, this study employs a strategy to minimize cell count while meeting the building’s maximum demand. Hydrogen and natural gas are employed as fuels for system utilization. To satisfy the average electricity power, the system efficiency fueled by hydrogen and natural gas is 90.3% and 90.1%, while the electrical efficiency is 63.0% and 48.1%, respectively. When conditions change to meet the peak electricity power, the system efficiency drops to 67.2% and 71.2%, and electrical efficiency drops to 30.7% and 23.8%, respectively. Power supply and heat supply need to be comprehensively considered and flexibly regulated, and efficient operation modes should be adopted as far as possible under the premise of ensuring building energy consumption.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
