Recent achievements in direct ethylene glycol fuel cells (DEGFC)

In the present review recent achievements in the development of new type of liquid fed fuel cell, specifically ethylene glycol (EG) operated in acid and alkaline media were summarized. The mechanism of EG electrooxidation in acid media on the platinum surface as well as on different platinum alloys is described. The development in the preparation of new effective electrocatalysts both for ethylene glycol oxidation and oxygen reduction in the presence of EG is discussed. Methods for improving the performance of direct ethylene glycol fuel cells (DEGFC), e.g., MEAs fabrication, operation conditions, etc. are shown.
