Description

technical field [0001] The present invention relates to the technical field of fuel cells / electrolyzers, in particular to a method for preparing a solid oxide fuel cell / electrolyzer connector. Background technique [0002] Solid oxide fuel cell (SOFC) is a kind of fuel cell, which is an all-solid-state power generation device that directly converts chemical energy in fuel into electrical energy through chemical reaction. It is mainly composed of anode layer, electrolyte layer and cathode layer. Compared with the traditional heat engine power generation technology, the biggest feature of SOFCs is that the power generation process does not involve combustion, so its energy conversion efficiency is not limited by the Carnot cycle. The primary electrical efficiency can reach 50%-60%, and after linkage with the steam turbine, the energy conversion efficiency can reach more than 80%. At the same time, SOFC is environmentally friendly, with low pollutant emissions during power gen...
