Description

technical field [0001] The invention belongs to the field of fuel cells, and more specifically relates to a numerical simulation method of a flat solid oxide fuel cell. Background technique [0002] A fuel cell is an efficient and environmentally friendly power generation device that directly converts chemical energy stored in fuel and oxidant into electricity. Among them, the solid oxide fuel cell (SOFC) does not require expensive metal catalysts and fuel pretreatment, has only gas-solid two-phase, simple working principle, etc., and is known as one of the most promising fuel cells. However, the experimental cost of solid oxide fuel cell is too high, the cycle time is long, and it is easily affected by experimental equipment, which restricts the research progress of SOFC. Numerical simulation method is low in cost and high in efficiency, and it can optimize the design and analysis of SOFC from multiple aspects such as operating parameters, structural design, and material p...
