Description

technical field

[0001] The invention relates to a solid fuel cell, in particular to a solid oxide fuel cell supported by stainless steel and a preparation method thereof. Background technique

[0002] Solid oxide fuel cell (SOFC) is a new energy conversion device with high efficiency and cleanliness. Its various key materials, research and development of preparation technology, as well as corresponding battery configuration and battery stack design have been well received by researchers and scientific research institutions all over the world. of general concern. Generally speaking, the configuration of SOFC single cell mainly includes three types: electrolyte support (ESC), anode support (ASC) and cathode support (CSC). For these three configurations of single cells, their supports are all brittle ceramic or cermet materials in composition, and also contain more or less noble metal materials. Considering the low cost, high conductivity, high strength and easy processing ch...
