초록
Direct methanol fuel cells (DMFC) employing proton exchange polymer electrolyte have recently gained considerable interest because of their attractiveness as the power source for electronic devices or vehicular applications. However, it suffers from the fuel crossover and its impact on cathode operation and the consequent penalty in system energy efficiency. Efforts to circumvent the methanol crossover in DMFC have been made basically along three different strategies.(Omitted)
