Description

technical field [0001] The invention belongs to the technical field of solid oxide fuel cells, and more specifically relates to a multi-modal analysis model modeling method for a solid oxide fuel cell system. Background technique [0002] Solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) is an all-solid-state chemical power generation device that directly converts the chemical energy stored in fuel and oxidant into electrical energy efficiently and environmentally friendly at medium and high temperatures. Pollution, no mechanical vibration and wide adaptability to various hydrocarbon fuel gases make it one of the most attractive green power generation methods in the 21st century. [0003] SOFC can be used in civil fixed power plants, airborne aerospace, heat and electricity recycling, transportation and many other fields, and its research and development have flourished since the 1980s. Some developed countries, such as the United States, Germany, and Japan, have devoted ...
