Abstract:

Direct methanol fuel cells are promising power sources because of their advantages such as high power densities and good portabilities. With the development in technologies and the progress towards commercializations, the operating stability becomes more and more important. Among many factors resulting in cell performance losses, the deterioration of electrocatalysts, the variation in membrane electrode assembly structures, and the contamination caused by impurities play important roles. In this paper, recent studies concer-ning the performance degradation of direct methanol fuel cells are reviewed, and several factors influencing the operating stability of fuel cells are discussed.

Key words: Direct methanol fuel cell, erformance degradation, tability
