摘要：

Influence of cell pressure and amount of electrode catalyst in membrane electrode assembly (MEA) on the amount of methanol crossover of direct methanol fuel cell (DMFC) was discussed. MEAs with an electrode area of 25 cm2 were prepared using Nafion 112 membrane, Nafion solution and an electrode catalyst. Results showed that an increase in the amount of electrode catalyst improved the DMFC performance and slightly decreased the amount of methanol crossover.
