The cell has the advantages of reasonable structure and good working performance.

Description

Technical field: [0001] The invention relates to a direct methanol fuel cell group. Background technique: [0002] Direct methanol fuel cells (Direct Methanol Fuel Cell, DMFC) directly use liquid methanol as fuel, and there is no need to add other devices except for an extremely simple methanol storage. Methanol fuel is easy to carry and replace, and it is very convenient to use. Therefore, in the past 10 years, The development and application of DMFC technology is developing rapidly. Many universities, research institutes and major companies at home and abroad have spent huge manpower and material resources on DMFC research and development. The focus of the research is to reduce the cost of DMFC, improve the performance of DMFC, and be suitable for commercial use. [0003] DMFC with a circular structure has unique advantages when used as a power battery for portable electric devices and a household power supply. In the research of circular DMFC, there are research reports...
