直接甲醇燃料电池中CO2传质的研究

摘要

In order to promote the effective mass transfer of CO2 in direct methanol fuel cell (DMFC) and improve the performance of DMFC, in this paper, the application prospects and the present problems of DMFC were summarized, the operation principle was simply introduced, the mass transfer mecharism of CO2 in the DMFC electrolyte was analyzed and the impact factors were illustrated. The previous study on the status of CO2 mass transfer was introduced, and a ne vision for CO2 mass transfer was brought forward.%为了促进直接甲醇燃科电池(DMFC)中CO2的有效传质,从而提高其性能,综述了DMFC的应用前景及面临的问题,简单介绍了DMFC工作的原理,分析了DMFC中CO2的传质机理并进一步阐述了其影响因素,介绍了前人对CO2传质研究的现状,并在此基础上提出了研究CO2的新设想.
